The Hedland Flow Meter is not bidirectional. The piston acts as a check valve to block flow in reverse direction. It can be installed immediately adjacent to a right angle elbow or other piping fixture, giving you greater system design flexibility, as well as saving time and money during installation. The unique magnetic coupling also eliminates the need for mechanical linkages that can wear or loosen over the functional life of the meter. The piston's sharp-edged orifice also assures greater operating stability and accuracy over a wide range of viscosities.
Special scales are available in other units of measurement or specific gravities.
There are no invasive mechanical linkages, electrical probes, or other costly maintenance elements in this design.
