Flow Measurement
Variable Area Flowmeters
Glass tube Variable Area Flowmeters

R-101-E is a glass tube type variable area flowmeter. The flow rate is indicated by the position of float and the graduation engraved on the glass tube.
Although it has a very simple construction, it is widely used for measurement of flow rate of liquids and gases in various applications thanks to its high reliability and easy handling capability.
A large sized tapered tube is adopted compared to standard type glass tube flowmeters and wide scale range is possible.
In addition to standard material of steel and stainless steel, PVC is also available for corrosive applications.

Features

  • Larger flow range in same size
    Wider opening glass tube offers larger flow range compared to standard glass tube meters.
  • 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 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.
