Variable-Area

Below, the process fluid flows through our meter at a rate of 3 GPM. The flow causes our sensor, a spring-loaded cone/magnet assembly, to move from a large precision orifice. As flow increases, the sensor magnet moves towards the pointer magnet and the reed switch to actuate. The cone-orifice combination results in variable-area flow measurements and an easy-to-read linear scale. The reed switch alerts the user of problem conditions.

 

The process fluid flows through the entire meter by way of the variable-area orifice and then the openings in the flow cone and magnet.

 

Our fixed orifice flowmeters (not shown) use a similar design but there is a single small orifice/diaphragm assembly that allows for readings on a square root scale. This design is intended for low flow and clean fluid applications.
Orange Research is your source for differential pressure gauges, differential pressure switches, differential pressure transmitters, flow switches, flow transmitters, flow meters and level switches. Some of the many applications for these products are filtration, compressors and heat exchangers for a wide variety of industries including petroleum, chemicals and semiconductors, just to name a few!
