General information

The unique spring loaded design of this variable area flow meter for common fluids reduces viscosity sensitivity. Variable area meters are in-line meters.The Hedland® variable area flow meters are the most readable products in their class to monitor a wide range of liquids, petroleum-based fluids, Phosphate ester liquids, water, water-based fluids or water/oil emulsions. A pneumatic series is also available for metering air and compressed gases. All meters are available as basic flow meters, test kits or for high temperatures, corrosive liquids and gases.

Measuring principle

Variable area flow meters

Variable area flow meters

The variable area flow measurement method allows fluids (liquids and gases) volume streams to be determined. A moving sharp-edged orifice is located within the piston assembly, forming an annular opening with the contoured metering cone. The piston assembly carries a cylindrical PPS/ceramic magnet that is magnetically coupled to an eternal indicating magnet, which moves precisely in direct response to movement of the piston therefore providing a visual display of the flow rate.
