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

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

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
