What is a Flow Switch / Sensor
Flow switches are used to monitor and control the flow rate of fluid within an industrial process system. Flow switches respond to pre-set flow rate levels and perform two functions when those levels are reached: namely, closing its contacts and turning a specific piece of equipment ON, or opening its contacts and turning a specific piece of equipment OFF.
A flow sensor is a component that measures the flow of a fluid such as a gas or liquid. Flow sensors utilize both mechanical and electrical subsystems to measure changes in the fluid’s physical attributes and calculate its flow.
