[0034] FIG.1 shows a top view of an apparatus 100 for measuring weight, in accordance with an embodiment of the present disclosure. As shown in FIG. 1, multiple syringes 102 (also referred as first displacement pumps 102, herein) can be disposed on a base 104 of a cabinet (also referred as box, herein). The cabinet can be made of but not limited to wood, plastic, metal. The first displacement pumps can be interconnected to each other as shown in FIG. 3. As shown in FIG. 1, the apparatus 100 can include vertical walls 10 (also referred as channels 10, herein). An upper plat (also referred as platform, herein) can be disposed over a displaceable portion/piston side of the first displacement pumps 102. The platform can be used to place an object whose weight is to be measured. The upper plate can include slots (also referred as cut outs, herein) that can be corresponding to the vertical walls. The slots can accommodate the vertical walls while vertical movement of the platform. In an embodiment, the first displacement pumps can include fluid that can be incompressible fluid so that the pressure on the platform can be transferred to the first displacement pumps without any loss. When the object is placed on the platform, the displaceable portion of the first displacement pumps can be pressed/actuated by it weight. The actuation of the displaceable portion cab cause release of some fluid from first displacement pumps which further cause change in fluid volume in the first displacement pumps. The released fluid of all the syringes can be collected in another syringe (also referred as second displacement pump, herein) outside the cabinet. The fluid volume in the second displacement pump can be used to measure weight of the object.
[0035] In an embodiment, a change in the fluid volume of the first displacement pumps 102 can be calculated using following equation:

where, p is pressure applied by the object weight
v is volume of fluid in each syringe
B is Bulk Modulus
Pressure can be calculated using following equation:

where, m is mass of object placed on the platform
g is gravity i.e. 9.8 m/s2
A is area of the base
Further, value of pressure can be put in to equation representing the fluid volume chance and the final equation can be represented as:

[0036] In an embodiment, a combined output of changes in fluid volume from the first displacement pumps 102 can be represented as sum of fluid volume change from every first displacement pump. If all the first displacement pumps are identical the combined output can be represented as follow:

If the first displacement pumps are not identical, the combined output can be represented as follow:
[0037] In an embodiment, the change in volume of fluid can be so chosen that it remains uncompressible can does not put intolerable pressure on tube walls of connecting pipes that are interconnecting the first displacement pumps. The fluid can be but not limited to water. The fluid release by first displacement pumps can be received by second displacement pumps which can be outside the cabinet and can be of a greater diameter. The fluid collected by the second displacement pump can be used to calibrate/detect/determine weight of the object using least count of the apparatus. The equation for calibrating object’s wright can be represented as follow:

where, ? is machine constant
[0038] FIG. 2 illustrates a side view of an apparatus 200 for measuring weight, in accordance with an embodiment. As shown in FIG. 2, a base 206 of the apparatus can include multiple syringes (also referred as fist displacement pumps, herein) and displaceable portion systems” 204. A platform 202 can be placed on displaceable end/portion of the first displacement pumps. The FIG. 3 shows interconnection between the first displacement pumps/syringes, in accordance with an embodiment of the present disclosure. The first displacement pumps 102 can be interconnected by using connecting pipes and connectors.
[0039] FIG. 4 shows a prototype of the proposed apparatus. Sensitivity of the apparatus can be increased by placing the first displacement pumps 102 inside a syringe cylinder. Stretch or compress of the spring can be analogous to change in fluid volume in the first displacement pumps. To increase the sensitivity and reduce change in the fluid volume (in syringe) per unit mass, springe constant of the first displacement pumps can be high. FIG. 5 shows a bottom view of prototype of the apparatus, in accordance with an embodiment of the present disclosure.
