The Yokogawa RAGN Rotameter is designed for continuous flow measurement of liquids and gases. The fluid passes through the metering tube from bottom to top and consequently needs to be installed vertically and flow direction is upwards. The conical glass metering tube includes a free rotating float which provides self stabilization. The actual flow is indicated by the top of the float and can be directly read from the scale on the metering tube.

Applications include:

  • Visual fluid monitoring
  • Industrial gas measurement
  • Controlling of water circuits
