*Specifications are subject to change without prior notice.

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
  • · Maintenace free and long stable operation
