Max Water Flow Rate (mL/min)

Differential Pressure Flowmeters

Differential Pressure Flowmeters
Differential pressure flowmeters measure flow via pressure drop across a laminar flow element (LFE). A pressure drop is created as water or gas enters through the meter's inlet. The fluid is forced to form thin laminar streams that flow in parallel paths between internal plates separated by spacers. The pressure differential created by the fluid drag is measured by a differential pressure sensor connected to the top cavity plate. The differential pressure from one end of the laminar flow plates to the other end is linear and proportional to the flow rate of the water or gas.
