*Specifications are subject to change without prior notice.

W-800 Mini-Wheel Flowmeter measures flow rate of liquids such as cooling water by counting the number of the built-in wheel's rotation. The liquid wetting parts consist of fluoro resin. (Only the shaft is made of quartz glass.) So, the introduction of metallic ions into the liquid is eliminated. Many kinds of scale ranges are lined up.

Features

  • · Material made of fluoro resin: No possibility of introducing metallic ions into the fluids
  • · For measuring very small to medium flow rate: Various scale ranges lined up
  • · Optical sensing method
