Data Sheet / Catalogue

Principle of Operation:

"Ji" Japsin Instrumentation Digital Flowmeter operates on the principle of Variable Area; when a fluid or gas flow through a taper tube containing a float, a pressure difference of P1 and P2 is created between the upper and lower side of the float. 


The float moves upwards by a force obtained by multiplying the pressure differential by the maximum cross-sectional area of the float. 


Due to the nature of the taper tube as the float moves upwards, the fluid passing area increases as a result of which the differential pressure decreases. 


The upward movement of float stops when the dead load is dynamically balanced by the differential pressure. 


The tapering of the metering tube is so designed that the vertical movement of the float becomes linearly proportional to the rate of flow and the scale is provided to read the position of the float, thus bringing birth to the flow indication.
