Tokyo Keiso R-700 Glass Tube Flowmeter
Made in Japan
Manufacturer: Tokyo Keiso
Model: R-700
R-700 is a series of Glass tube flowmeters with alarm contact. The flow rate of liquids and gases is indicated by the position of float and graduation on glass tube. Additionally, alarm contact is obtained at set position. R-700 acts as Flow switch as well.
Features
- Alarm contact provided
In addition to flow indication, alarm contact is provided.
- Easy installation
No straight runs both for upstream and downstream are 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 liquid
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.
