*Specifications are subject to change without prior notice.

The W-200 is a rotary vane type flowmeter for measuring liquids.The rotary vane containing a magnet is placed in the stream. Theflow rate is measured without contacting the wheel by detectingthe number of rotations which is proportional to the flow rate. The compactly designed flowmeter with its body made of resin is non-metallic for all wet parts.


  • · Pulse, voltage, or current output
  • · Visible wheel rotation
  • · The model of its body made of resin is non-metallic for all wet parts
  • · Easy overhauling, cleaning and maintenance
  • · Compact shape
