*Specifications are subject to change without prior notice.

The W-500 series is a flowmeter with a wheel for liquids. A magnet is built into the wheel, and the fl ow rate is measured by detecting the number of rotations of the wheel, which is proportional to the fl ow rate.
With various materials and functions, the W-500 series can be used for a wide variety of applications including plant and water treatment facilities.

Features

  • · Either a resin or metal flow tube can be selected.
  • · Local or separate flow indication without power supply, 4 to 20 mA
    DC output (2-wire), and pulse output can be selected.
  • · Flow rate range is from 0.7 to 3.5 m³/h (min.) to 50 to 400 m³/h (max.).
  • · Easy reassembling/assembling, cleaning, and maintenance
  • · Excellent cost performance
