VDT Series Wafer-Cone Flowmeter

Brand: Tokyo Keiso Co, Ltd

VDT series is the indicator integrated type Wafer-Cone® differential pressure flowmeter; VH series Wafer-Cone® flowmeter and DT series multi digital differential indicator 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. Shorter straight runs and lower pressure loss than orifice save your construction cost and energy.
