Variable-Area Flow Meters
Our flow meters are designed for those applications where a rotameter is not appropriate. Consider the inherent problems of rotameters – they are difficult to read, especially with dirty or opaque fluids, have low pressure ratings and allow vertical orientation only. Now consider that Orange Research high pressure flow meters have large dials with bold markings and characters that are easy to read from a distance, handle high line pressures and can be mounted in any orientation.
Like rotameters, flow meters are mounted directly in the flow stream, but with bodies machined from solid blocks of metal, they handle high-pressure applications of up to 5000 psi (vs 150 psi for rotameters). This makes our high pressure flow meters a natural for hydraulic and pneumatic systems.
These variable-area flow meter models are designed for medium- to high-flow applications. The flow meter sensor, a movable Delrin cone, rests in a precision orifice. Changes in fluid flow cause the sensor to move against a stainless steel spring while the flow rate is indicated on an easy-to-read dial face.
We offer our flow meters with bodies (and wetted parts) of aluminum, stainless steel or brass. A variety of dial sizes are available, from 2.5 inch to 4.5 inch. Choose from a wide selection of standard options; enough to satisfy any requirement.
Switches, Relays, Transmitters
A variety of reed switches, relays and transmitters can accompany our high pressure flow meters, or they can be supplied on their own, without a dial. SPST switches are offered normally open (N.O.) or normally closed (N.C.). SPDT reed switches also are available. DPDT relays are offered for high inductance applications, such as those incorporating motors or solenoids. Transmitters offer a current or voltage output.
