Positive Displacement Flowmeter

 

isolvPositive Displacement Flowmeter. The measuring chamber of the iSOLV Bi-Rotator positive displacement flowmeter consists of a body, a pair of rotor gear and a top cover. A cavity with a known volume is formed and functions as the measuring chamber of the flowmeter.

The bi-rotators rotate under the minimum change in pressure between the inlet and outlet. Rotations send the liquid from the inlet to the outlet. The rotation of the two rotators is directly proportional to the volume of liquid passing through.

The mechanical rotations of the bi-rotators are transmitted to a mechanical totalizer or electronic counter for flowrate and totalizer display.
