*Specifications are subject to change without prior notice.

The W-300 is a rotary vane type flowmeter for measuring liquids.
The rotary vane containing a magnet is placed in the stream.
The flow rate is measured without contacting the wheel by detecting the number of rotations which is proportional to the flow rate.
A wide variety of materials for body materials and various kinds of outputs are available to meet every application.

Features

  • · Pulse, voltage output
  • · Visible wheel rotation
  • · The model of its body made of resin is non-metallic for all wet parts
  • · Easy overhauling, cleaning and maintenance
  • · Complying with customers’ requests for materials and connectors.
