Variable Area flow meters measure volumetric flow of liquids and gases. This technology is based on the variable area principle, where flow raises a float in a tube, increasing the area for passage of the fluid through the meter.
Hedland Variable Area flow meters provide a quick, visual flow indication on an easy-to-read linear scale to confirm that flow systems are operating properly.
Variable area meters measure volumetric flow of liquids and gases. An orifice is positioned within the piston assembly and forms an annular opening with the contoured metering cone. The piston assembly carries a cylindrical ceramic magnet that is coupled to an external flow indicator that moves precisely in direct response to the piston movement. A calibrated spring opposes flow in the forward direction, decreasing viscosity sensitivity.
Our line of Hedland® products features over 18,000 inline variable area flow meters suitable for oil, phosphate esters, water, water-based liquids and compressed gases. Capable of operating in any position in high-temperature and corrosive applications, Hedland® meters are easy to read and built for use in rugged environments.
