R-100 Series

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 flowmeasurement.
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.
