VNT Series Wafer-Cone Differential Pressure Flowmeter

Brand: Tokyo Keiso Co, Ltd

VNT series is the transmitter integrated type Wafer-Cone® differential pressure flowmeter; VH series Wafer-Cone® flowmeter and precision transmitter are integrated into one flowmeter. Its principle is based on the Bernoulli's theorem like orifice flowmeter.

The V-cone inside pipe throttles flow and generates differential pressure corresponding flow rate. The precision cast body made in lost wax process has a simple and rigid construction. Succeeding various features of V-cone flowmeter, it realized low cost flow measurement. It measures liquids, gases and saturated steam with high temperature.
