FIELD OF THE INVENTION

The Present invention is related to develop a new automatic meter for reading water flow rate using GSM module.

BACKGROUND OF INVENTION

Water meter is a device for measuring and registering the volume of water that passes through the pipe or outlet. It is both mechanically and electrically controlled meter. In many developed countries water meters are used to measure the volume of water used by residential and commercial building that are supplied with water by a public water supply system. Water meters can also be used at the water source, well, or throughout a water system to determine flow through a particular portion of the system. The water metering device has a drawback that since it has been located in an open surrounding which leads to absence of continuous monitoring it can be easily tampered by the civilians. Due to absence of continuous monitoring the authorities are unable to find the illegal users. The billing system that is used for this kind of meter are conventional type, hence a person should be assigned to visit each home/building/industry to obtain the readings for calculating the billing amount. This processes need more time and sometime human-error can occurred during this process. Hence the billing system has become inaccurate and inefficient. Here we developed a new technique for acquiring the meter reading automatically, transfer and receive data from central unit through a GSM module.

SUMMARY OF THE INVENTION

In this proposed system we developed a new technique for acquiring the meter reading automatically, transfer and receive data from central unit through a GSM module. A Hall effect sensor is placed close to the water meter turbine where it can acquire the magnetic pulse send from the magnet and send it to the arduino nano (ATmega328 processor) where it convert the magnetic pulse to an actual flow rate. The converted data will be send to the PC through the GSM module. The Arduino nano is interfaced with a Solenoid valve, when any illegal activities like tampering is performed the valve will stop the flow rate and an alert message will send to the authority.

DETAILED DESCRIPTION

A Water flow meter is a device used for measuring and registering the quantity of water that pass through a pipe outlet. The flow rate are calibrated in both cubic metres (m3) or litres and cubic feet (ft.3) or gallons. The process of measuring the water flow is called water metering. As water flows through the meter it tends to rotate the turbine fins, where a magnet is attached in the top of it. The Turbine is an individual rotating object that is made up of plastic, .which is responsible for obtaining the flow rate in the water meter. The flow rate is acquired by the rotational movement of the turbine engaged by water through the turbine fins. A magnet is attached in the top of the turbine, which is in a close contact with the Hall Effect sensor. When the turbine engage to rotate, the magnetic Pole come in contact with the sensor and a magnetic pulse is generated and obtained by the sensor. The Base of the water meter is an individual brass component that allows the water to flow through it, a plastic seal is placed over its to prevent the water leaking out of it and to prevent the turbine from wobbling. A small cylindrical iron is attached in the middle of the base to prevent the uneven rotation and turbine dislocation when the water is flowing through the base.

A Hall Effect sensor is a transducer that varies its output voltage in response to a magnetic field. In other words it is a device which convert magnetic or magnetically encoded information in to electrical signal. The sensor is positive and digital is interfaced with the 10k resistor in order to prevent the circuit form facing high voltage by reducing current flow, and, at the same time, act to lower voltage levels within circuits. When a beam of charged particles passes through a magnetic field, forces act on the particles and. the beam is deflected from a straight path. The flow of electrons through a conductor is known as a beam of charged carriers. When a conductor is placed in a magnetic field perpendicular to the direction of the electrons, they will be deflected from a straight path. As a consequence, one plane of the conductor will become negatively charged and the opposite side will become positively charged. The voltage between these planes is called Hall voltage. When the force on the charged particles from the electric field balances the . force produced by magnetic field, the separation of them will stop. If the current is not changing, then the Hall voltage is a measure of the magnetic flux density. Basically, there are two kinds of Hall effect sensors. One is linear which means the output of voltage linearly depends on magnetic flux density; the other is called threshold which means there will be a sharp decrease of output voltage at each magnetic flux density.

The water meter is interfaced with a hall effect sensor in order to measure the flow rate. When the water runs through the meter it tends to rotate the turbines fin. A magnet is attached to the top of turbine. When the turbine start to rotate the magnet start rotating relatively to it. A hall effect sensor is placed near to the magnet in a close magnetic field, the sensor will start receiving the magnetic pulse which will transfer the pulse to the arduino nano. A program have, been developed in the arduino nano to perform the calculation where the program converts the magnetic pulse into actual flow rate. The arduino nano is interfaced with a GSM module. GSM module is a mobile communication modem that act as a two way data transmission module with a SIM attached to it, which establish communication between a computer and a cellular network and transfer data via SMS. The ARDUINO will send the data to the GSM module and with a time delay the module will send the data to receiving end. There was GSM module will be interfaced with the ARDUINO NANO which is connected to the computer/display. The meter is attached with the solenoid valve in term when the meter is tampered the module will send the alert message to the computer and the valve will be closed by the solenoid valve and remains close until the tamper is rectified.
