*Specifications are subject to change without prior notice.

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.

Features

  • · Easy installation with wafer construction
  • · Direct mounting of compact differential transmitter requires no impulse piping
  • · Measuring liquids, gases and steam
  • · Less than 1/5 of orifice straight runs
  • · Stable differential pressure 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 and maintenace free with stable operation

Applications

  • · Steam and water flow management
  • · Flue gas flow management
  • · HVAC(Heating ,ventilation and Air conditioning) system
  • · Water treatment facilities
  • · Refuse incinerator plants
  • · Co-generation plants
