Differential pressure Flowmeters
Wafer-Cone® Flowmeters

VH series Wafer-Cone® differential pressure flowmeter and small sized Variable Area flowmeter are integrated into one Wafer-Cone® bypass flowmeter. As the meter requires little straight runs and little head loss compared to orifice plate, it offers you reduction of construction cost and energy saving.
