How Does A Flow Switch Work?



What is flow switches?

A flow switch is simply a device that monitors the flow of liquid, gas, or steam. When the flow reaches a certain pre-set flow rate, a switch is triggered that has the capability to signal an action, such as shutting down the flow entirely. This is done through electrical signals created by the switching mechanism. They usually consist of a primary mechanism, such as a paddle or magnetic trigger, which is connected to a sensor. This mechanism is placed in the media flow. The flow causes the switch to be displaced or the paddle to be rotated, sending a signal to a secondary component known as the transducer. The transducer takes the signals from the primary mechanism, converts it to a more usable signal and passes it on to a transmitter.


Where are flow switches used?

There are many industrial applications where flow control is important, some of the critical areas including oil and gas, pharmaceutical and water treatment. On a more domestic scale, air conditioning systems, central heating systems and pool pumps would include flow switches within their operating systems.
