Tokyo Keiso R-100 Glass Tube Flowmeter

Made in Japan

Manufacturer: Tokyo Keiso

Model: R-100

R-100 is a series of Glass tube flowmeters. The flow rate of liquids and gases is indicated by the position of float and graduation on glass tube. No utility supply such as electricity and/or air for operation. The best cost effective flow measurement is possible.

Features

  • Easy installation

No straight both for upstream and downstream is required for process installation. No utility supply is needed.

  • Cost effectiveness

The pure mechanical construction offers most cost effective flow measurement.

  • Direct observation of measuring fluid

In addition to flow rate measurement, the measurement fluids are directly observed for better process fluid quality control.

  • Wide material selection

Besides the standard metallic material, resins and/or lining materials are available for corrosive fluids.
