Flow Measurement
Variable Area Flowmeters
Glass tube Variable Area Flowmeters

R-700 is a series of Glass tube flowmeters with alarm contact. The flow rate of liquids and gases is indicated by the positon of float and graduation on glass tube. Additonally, 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 flowmeasurement.
  • 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.
