Made in Japan

Manufacturer: Tokyo Keiso

Model: W-2000/W-2000N

W-2000 and W-2000N are the rotary vane type flowmeters suitable for various liquid flow measurement.
W-2000 has a window through which operators can watch the rotation of the wheel and the flowing status of liquids.
W-2000N covers wider range of temperature.
Made by precision casting, both compact-designed and cost-effective flowmeters are suitable for the measurement of the various cooling water devices and semiconductor chillers.

Features

• Pulse or current output
• Visible wheel rotation
• Covering wide temperature range from -20 to 100°C
• Wide variety of material groups to cover many kinds of fluids
• Easy overhauling, cleaning and maintenance
• Low price owing to intensive cost down
• Complying with RoHS
