Tokyo Keiso VH Series Water-cone Flowmeter
Made in Japan
Manufacturer: Tokyo Keiso
Model: VH
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
