FIELD OF THE INVENTION
[0001] The present invention relates to a liquid level indicator for a
vessel. More particularly, the present invention relates to a device which indicates
the level of the liquid filled in the vessel.
BACKGROUND OF THE INVENTION
[0002] In recent, a trend has been observed that with the increase in the
per capita income, the spending on eating and drinking has gone up. This trend is
vivid mainly in eateries ranging from small cafes to high end fine dine restaurants.
People come to these places for eating, along with that they sip variety of breweries
and drinking items, which ranges from alcohol to as simple as plain water. There
are people who likes to sip their beverages through sippers. Sippers are a hollow
pipe like structure nowadays very popular for sipping either hot or cold beverages.
The beverages include cold drinks, cold coffee, fruit juices etc. People even, sip
plain water through sippers for ease in drinking.
[0003] Since, many people gulp waters in one go therefore, these sippers
come handy in avoiding gulping of liquid. Furthermore, there are people who likes
to stir their beverages before consuming the same ergo, stirrers are very popular
among lots of people. Stirrer is a pipe like structure that comes in different shapes
and sizes. The main function of these stirrer is to stir the liquid such that to mix
different ingredients dissolved in the liquid properly.
[0004] Notwithstanding, the soaring footprint of people in these eateries,
has brought to light, that managing the significant number of people is a herculean
task for the management of these eateries. The reason for this is the difficulty faced
by the waiters serving specially the drinks like water, alcohol, juices or other
breweries, to keep an eye on the same, that which persons glass is full, empty or
half filled. Although, vessels are transparent but some people cover their vessel with
napkins.
3
[0005] Therefore, it is cumbersome for the person serving them to
anticipate or find out which glass is empty, full or half filled. Most terrible thing is
that there is no mechanism to address this issue fully. Moreover, the problem to
anticipate the level of liquid is still unresolved yet.
[0006] There exists a need to develop a device that detect the level of
liquid filled within the vessel and enabled to inform the person serving to the
people’s having all types of drinks about the level of the drink in the vessel.
SUMMARY OF THE INVENTION

4
[00013] Another object of the present invention is to provide a device that
is completely washable, light weight, sturdy, rugged and reusable.
[00014] Still another object of the present invention is to provide a device
that is compact and reliable in nature.
[00015] Other objects and advantages of the present disclosure will be
more apparent from the following description, which is not intended to limit the
scope of the present disclosure.
[00016] In view of the above objects, in one aspect, the current disclosure
provides, a device for indicating level of liquid in a vessel. The device comprises
an elongated tube of length ranging between 10cm – 20cm. However, the length of
the elongated tube depends upon the size of the vessel with which the elongated
tube is being used. The elongated tube is placed in a vertical or a slanting position
within the vessel. The device which is an elongated tube is hollow and of annular
shape, that is employed either as a straw or a stirrer for either sipping or stirring the
liquid in the vessel or both. The scenario wherein the elongated tube is employed
as straw, enables a person to easily sip any liquid ranging from hot to cold beverages
that includes tea, coffee, alcohol, plain water etc. The same elongated tube is also
employed as a stirrer that enables a person in stirring any sort of liquid ranging from
hot to cold beverages like cold coffee, alcohol, tea etc.
[00017] Moreover, either end of the elongated tube is made of metal to
accommodate a pair of battery for smooth and uninterrupted functioning of the
device. One of the two battery is placed at the top of the elongated tube and the
second battery is placed at the bottom of the elongated tube. Furthermore, rest
portion of the elongated tube is transparent and made up of heavy duty transparent
material, so that the transparent material of the elongated tube reflects the light in a
5
manner that glow of the light facilitates the concerned person in monitoring the
level of liquid in vessel.
[00018] Further, multiple sensors are configured along the length of the
elongated tube to sense the level of liquid in the vessel and produce sensed data
regarding the level of the liquid in the vessel and the sensed data is send to a
processing unit for further processing and analysis. The number of sensors depend
upon the length of the elongated tube utilized, and the sensors are placed in between
the metal parts of the elongated tube. The sensors are arranged one after the other.
One out of the multiple sensors is placed just below the metal part of the elongated
tube such that to sense whether the vessel is full or below the full level. Another
sensor is placed at the middle part of the elongated tube to sense whether the vessel
is half filled or below half. One another sensor is placed at the bottom of the
elongated tube to sense whether the vessel is emptied or slightly filled. The sensors
provided in the device are selected from a water activated sensors, an alcohol
activated sensor and a colloidal solution activated sensor.
[00019] The processing unit is wirelessly coupled with all the sensors
placed along the elongated tube. The processing unit is a microcontroller that is
communicably coupled to the multiple sensors through a wireless fidelity. This unit
processes and analyses the received sensed data from all the configured sensors
placed along the length of the elongated tube and sends all the data to multiple
indicators placed adjacent to each sensors respectively.
[00020] Furthermore, all the indicators are communicably coupled to the
processing unit through a wireless fidelity. The indicators after receiving the sensed
and analysed data from the processing unit illuminates one of the indicator among
the multiple indicators that is placed adjacent to one of the sensor. The indicator is
illuminated depending upon the level of the liquid present within the vessel, to
intimate a concerned person usually a waiter serving the liquid, for monitoring the
level of liquid in the vessel. Further, the monitoring of the level of liquid in the
6
vessel is based on the illuminated indicator among the plurality of indicator.
Moreover, there are three indicators placed adjacently to each of the sensor
respectively, and each indicator illuminates on detecting different level of liquid in
vessel by each sensor. For instance, the first sensor is placed to detect the full vessel
i.e., the vessel is completely filled or a bit lesser. Hence, when the first sensor
detects that the vessel is completely filled subsequently, the indicator adjacent to
the respective sensor emits a light with a first predefined colour. This glowing of
light with first predefined colour intimates the concerned person usually a waiter
serving the liquid that the vessel is completely filled. Similarly, when the second
sensor detects that the level of the liquid within the vessel is in between filled and
emptied, subsequently, the second indicator adjacent to the second sensor
illuminates by glowing a third predefined colour light intimating the concerned
person that the vessel is half filled. Lastly, when the third sensor detects that the
vessel is just about to empty, then the third indicator placed adjacent to the third
sensor illuminates by glowing the light with a second predefined colour which
intimates the concerned person that the vessel is about to empty and the same need
to serve if needed.
[00021] Further, the indicator is wirelessly connected to a hand-held
device. The hand held device is withheld by a concerned person that indicates the
condition of the batteries present in the elongated tube.
[00022] The above, and other objects, features and advantages of the
present invention will become apparent from the following description read in
conjunction with the accompanying drawings, in which like reference numerals

and manufacturing for those of ordinary skill having the benefit of this disclosure.
[00030] When introducing elements of various embodiments of the
present invention, the articles “a,” “an,” and “the” are intended to mean that there
are one or more of the elements. The terms “comprising,” “including,” and “having”
8
are intended to be inclusive and mean that there may be an additional elements other
than the listed elements. Any examples of characteristics are not exclusive of other
characteristics of the disclosed embodiments. Additionally, it should be understood
that references to “one embodiment”, “one aspect” or “an embodiment” or “an
aspect” of the present invention are not intended to be interpreted as excluding the
existence of additional embodiments or aspects that also incorporate the recited
features. A vessel (322) is defined as a body that holds any type of liquid that is
consumable, including but not limited to glass, tumbler, mug, jug, and pitcher.
[00031] Referring to FIGURE 1, the present invention depicts a device
(100) for indicating liquid level in a vessel (322), according to an aspect of the
present disclosure. The device (100) depicted in FIGURE 1 is an annular hollow
elongated tube (102) like structure very much akin to a sipper, for sipping any
beverages either hot or cold like tea, coffee, alcohol and as plain as drinking water.
Moreover, the device (100) is also employed as a stirrer to stir any liquid present in
the vessel (322). Again the liquid present in the vessel (322) includes tea, coffee,
alcohol etc. Further, the length of the elongated tube (102) ranges between 10cm –
20cm and is placed in a vertical or a slanting position within the vessel (322). The
elongated tube has three segments to accommodate electronic equipment’s such as
sensors, processors and indicators etc. The three segments are top, middle and
bottom part of the elongated tube (102).
[00032] In addition to this, three sensors (104, 106, 108) are configured
throughout the length of the elongated tube (102) in each of the segments i.e. top,
middle and bottom part of the elongated tube (102). The first sensor (104) is placed
in the top segment, second sensor (106) in the middle segment, and the third and
the last sensor (108) is placed in the third segment. Each sensor is communicably
coupled with the processing unit (110). All the three sensors (104, 106, 108) are
selected from a group of sensors which are a water activated sensor, an alcohol
activated sensor and a colloidal solution activated sensor. All the three sensors (104,
106, 108) after detecting the level of the liquid in the vessel (322) generate a data
9
in relation to that and transfers the same via the processing unit (110) to multiple
indicators (112,114,116) placed adjacent to each sensor respectively. For example,
first indicator (112) is placed adjacent to the first sensor (104) in the top segment
of the elongated tube (102), second indicator (114) is placed adjacent to the second
sensor (106) in the middle segment of the elongated tube (102), and the third
indicator (116) is placed adjacent to the third sensor (108) in the bottom segment of
the elongated tube (102).
[00033] In addition to this the plurality of indicators (112,114,116) are
communicably coupled to the processing unit (110) through a wireless fidelity
which helps in transmitting the sensed and analysed data to the plurality of
indicators (112, 114, 116) in form of signals. The indicators (112, 114, 116) after
receiving the sensed and analysed data in the form of signal from the processing
unit (110) illuminates one of the indicator among the multiple indicators (112, 114,
116). The indicator is illuminated depending upon the level of the liquid present
within the vessel (322), to intimate a concerned person usually a waiter serving the
liquid, for monitoring the level of liquid in the vessel (322). Further, the monitoring
of the level of liquid in the vessel (322) is based on the illuminated indicator among
the plurality of indicator (112, 114, 116). Moreover, there are three indicators (112,
114, 116) placed adjacently to each of the sensor respectively, and each indicator
illuminates on detecting different level of liquid in vessel (322) by each sensor. For
instance, the first sensor (104) is placed to detect the full vessel (322) i.e., the vessel
(322) is completely filled or a bit lesser. Hence, when the first sensor (104) detects
that the vessel (322) is completely filled subsequently, the first indicator (112)
adjacent to the respective sensor (104) emits the light with a first predefined colour.
This illumination of first predefined colour light intimates the concerned person
usually a waiter serving the liquid that the vessel (322) is completely filled.
Similarly, when the second sensor (106) detects that the liquid level within the
vessel (322) is in between the fully filled and emptied, the second indicator (114)
adjacent to the second sensor (106) emits third predefined colour light intimating
the concerned person that the vessel (322) is going to be emptied soon. Lastly, when
10
the third sensor (108) detects that the vessel (322) is about to empty, then the third
indicator (116) placed adjacent to the third sensor (108) emits the second predefined
colour light which intimates the concerned person that the vessel (322) is empty
and the same need to be served as per the requirement. However, the number of
sensors and indicators depend on the size of the elongated tube (102) as well as
number of levels to be detected by the device (100) as per the user’s requirement.
[00034] Referring to FIGURE 2, the present invention depicts, that the
either end of the elongated tube (202) is made of metal to accommodate a pair of
battery (218, 220) for smooth and uninterrupted functioning of the device (200).
Furthermore, rest portion of the elongated tube (202) is transparent and made up of
heavy duty transparent material, so that the transparent material of the elongated
tube (202) reflects the light in a manner that glow of the light facilitates the
concerned person in monitoring the level of liquid in vessel (322).
[00035] Furthermore, the indicators (212,214,216) are wirelessly
connected to the hand held device (118) possessed by the concerned person,
wherein the hand held device (222)shows the battery percentage of the device (200)
to the concerned person. The wireless connection between the indicators
(212,214,216) and the hand held device (222) is established through a
communication module. Further, the communication module is selected from a
Bluetooth module, Wi-Fi module, NFC module or GSM module.
[00036] Referring to FIGURE 3(a), the present invention depicts a
schematic view of the device when the device is dipped in the vessel (322)
completely filled with the liquid. However, FIGURE 3(a) illustrates that, the
elongated tube (302) is dipped in a fully-filled vessel (322), consequently all the
three sensors (304, 306, 308) and adjacently placed indicators (312, 314, 316) to
the three sensors (304, 306, 308) are also dipped in the liquid. Subsequently, the
top sensor (304) senses that the vessel (322) is fully filled and generates data
11
regarding the fully filled status of the vessel (322), further the generated data is
transmitted to the processing unit (310), which processes the generated data to
analyse the same. On basis of the analysed data, the processor (310) transmit a
signal to the indicator (312) placed adjacently to the sensor (304) to glow the first
predefined colour light. The light glows through the transparent body of the
elongated tube (302), which indicates that the vessel (322) is fully filled with the
liquid. The glowing of the elongated tube (302) is easily visible to any person
present nearby, further indicating the concerned person serving the liquid that
there is no need to pour liquid in the vessel (322) that has a glowing elongated
tube (302) with first predefined colour of light.
[00037] Referring to FIGURE 3(b), the present invention depicts a
schematic view of the device when the device is placed in a half filled vessel (322)
with the liquid. FIGURE 3(b) depicts that when the vessel (322) is half filled with
the liquid then only two sensors (306, 308) along with the two indicators (314, 316)
placed adjacently to the two sensors (306, 308) are dipped in the liquid present in
the vessel (322). Subsequently the sensor (306) senses that the vessel (322) is half
filled and generates data regarding the half-filled status of the vessel (322). Further
the generated data is transmitted to the processing unit (310), which processes the
generated data to analyse the same. On basis of the analysed data the processor
(310) transmit a signal to the indicator (314) placed adjacently to the sensor (306)
to glow the third predefined colour light. The light glows through the transparent
body of the elongated tube (302), which indicates that the vessel (322) is half-filled
with the liquid. The glowing of the elongated tube (302) is easily visible to any
person present nearby, further indicating the concerned person serving the liquid
that there is no need to pour liquid in the vessel (322) that has a third predefined
colour glowing elongated tube (302).
[00038] Referring to FIGURE 3(c), the present invention depicts a
schematic view of the device when the device is placed in a nearly empty vessel
12
(322). FIGURE 3(c) depicts that when the vessel (322) is nearly empty then only
the last sensor (308) along with indicator (316) placed adjacently to the same, is in
touch with the little amount of liquid present in the vessel (322). Subsequently the
last sensor (308) senses that the vessel (322) is about to get empty and consequently
generates data regarding the empty vessel (322). Further the generated data is
transmitted to the processing unit (310), which processes the generated data to
analyse the same. On basis of the analysed data the processor (310) transmit a signal
to the indicator (316) placed adjacently to the sensor (308) to glow the second
predefined colour light. The light glows through the transparent body of the
elongated tube (302), which indicates that the vessel (322) is about to get empty or
is emptied. The glowing of the elongated tube (302) is easily visible to any person
present nearby, further indicating the concerned person serving the liquid that there
is a need to pour liquid in the vessel (322) that has a second predefined colour
glowing elongated tube (302).
[00039] In an embodiment of the present invention, the processing unit
(210) is a microcontroller configured on the elongated tube (202) which comprises
a wireless fidelity to enable the data transfer from the processing unit (210) to the
multiple indicators (212,214,216) wirelessly. The device (200) is battery (218,220)
operated and has an inbuilt charging port for charging the device (200) in standing
and docking position. The device is of varied sizes and shapes, conducive for both
hot and cold beverages. It is made up of innocuous materials and the same is
washable as well. It is light weight and easy to handle as well as portable and
reusable.
[00040] In an exemplary embodiment of the present disclosure, the size of
the elongated tube taken here is 10-20cm according to the size of the vessel (322).
However, the size of the elongated tube is altered in accordance with size of the
vessel (322) in which it is to be dipped. Further, the number of sensors utilized
herein are three, however, the number of the sensor depends on the size of the
13
elongated tube and number of points located within the vessel (322) at which the
user wants to detect the level.
[00041] In another exemplary embodiment of the present disclosure, the
device determines the level of the drinks in multiple vessels positioned within a
specific area, while being served in any pubs, bars or clubs. The device uses sensors
to sense the level of the drinks in the vessels and the same is indicated through
indicators configured adjacent to the sensors. These sensors and indicators
combined together intimates the concerned person that is a waiter, serving the
drinks to the users, by glowing different coloured lights depending upon the status
of drinks filled in the glasses. For instance, when the user’s glass is fully filled a
light glow with a first predefined colour indicating the waiter that the glass is filled
and there is no need to serve that user. In another instance, when the user’s glass is
half filled then a third predefined colour light glows indicating the waiter, that the
glass is half filled and he needs to wait for the glass to be emptied. In the last
instance, when the user’s glass is emptied, a third predefined colour light glows
indicating the waiter, that particular glass needs to be filled or served depending
upon the requirement of the user, whether the user needs more drinks or the user is
done with it. Hence, in the aforementioned manner the present device assists the
waiter in getting to know the status of drinks present in each and every users glasses.
The first, second and third predefined colour of lights includes but not limited to
green, red and yellow indicating the level of liquid present within the vessel (322).
The first, second and third predefined colour of light are different from each other
and each predefined colour indicate a different level of liquid within the vessel
(322).
[00042] In another exemplary embodiment of the present disclosure,
referring to FIGURE 4, the circuit of electrical connection in between the sensors
(104. 106. 108) and indicators (112, 114, 116), consists of three transistor Q1, Q2
and Q3 act as solid state switch, which enables the indicators if the respective input
goes high to low signal through the liquid. Each of the indicators (112, 114, 116) is
having a pair of LEDs, so the total number of LEDs are 6. There are multiple
14
registers from R1 to R9, this is base biasing or transistor biasing. R2, R3, R4, R5,
R7 and R8 provide base biasing voltage for all the transistors. While R1 and R9 are
of 110 Ohms and 47 Ohms respectively, for current limiting resistor or pull up
register. The entire circuit is powered by 3.3V button cell. The sensors are TP2,
TP3 and TP4. If there is no fluid, the sensors do not have a signal that in turn do
not give signal to indicators and remain in cut off stage.
[00043] For example, in case the fluid is at the bottom level, the sensor TP
2 and TP 4 conducts through the fluid, TP 2 triggers the Q2 transistor which
saturates and LED D3 and D5 be on indicating the fluid level. When fluid rises to
the Top, TP 3 conducts due to which Q1 and Q3 gets triggers and D1 and D2 LED
turns ON to indicate the fluid level, and Q3 disables D3 and D5.
[00044] In addition, while the invention has been described with reference
to exemplary embodiments, it will be understood by those skilled in the art that
various changes may be made and equivalents may be substituted for elements
thereof without departing from the scope of the invention. In addition, many
modifications may be made to adapt a particular situation or material to the
teachings of the invention without departing from the essential scope thereof.
Therefore, it is intended that the invention not be limited to the particular
embodiment disclosed as the best mode contemplated for carrying out this
invention, but that the invention will include all embodiments falling within the
scope of the appended claims. Moreover, the use of the terms first, second, etc. do
not denote any order or importance, but rather the terms first, second, etc. are used
to distinguish one element from another. Furthermore, the use of the terms a, an,
etc. do not denote a limitation of quantity, but rather denote the presence of at least
one of the referenced item.
