How do Variable Area Flow Meters Work?

Blue-White variable area flow meters measure the volumetric flow of liquids. Flow raises a float in a tube, increasing the area for passage of the fluid through the meter.

Advantages of a Variable Area Flow Meter

  • Cost effective

    Low cost compared to other flow measurement devices

  • Reliable

    Trouble-free operation ensures years of accurate flow measurement and repeatability

  • Simple

    Very easy to install and maintain

  • Flexible

    No power required, which means they can be used virtually anywhere
