W-2000/W-2000N PDF

*Specifications are subject to change without prior notice.

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.
