This bench allows the study of industrial flow meters by comparing their measurement technique and their accuracy.
Determination of sensor characteristic curves and their accuracy
A centrifugal pump draws a non-compressible fluid (water) from a buffer capacity; this fluid is distributed via a membrane regulating valve and a float flowmeter on two pipes on which different flow sensors are mounted: a vane flowmeter, an electromagnetic flowmeter, a vortex flowmeter on the one hand, VENTURI and a standard diaphragm on the other hand (these two pressure-reducing devices are connected to a differential pressure sensor). The circulating fluid in closed circuit is returned to the buffer capacity.
The device is mounted on a stainless steel chassis, equipped with six adjustable feet.
