Variable-area flow sensor

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.

 

Fixed-orifice flow sensor

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.
