VH Series Wafer-Cone Differential Pressure Flowmeter

Brand: Tokyo Keiso Co, Ltd

Wafer-Cone® Differential pressure flowmeter is wafer connection version of V-cone 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.
Features
  • Easy installation with self-centering mechanism 
  • Measuring liquids, gases and steam
  • Less than 1/5 of orifice straight runs
  • Stable measurement at low flow rate
  • Stable low differential pressure measurement allows wide rangeability
  • Stable low differential pressure measurement allows low pressure loss 
  • Durable structure against wear or adhesion 
  • Maintenance free and long stable operation
