Flow switches help maintain safe and manageable rates of flow by triggering actions in various machines within a system to provide on/off flow control.

Electronic flow switches, also called flow monitors, provide the operator with a local indication of flow values and simultaneously an output of an electrical signal (PNP, NPN or 4-20 mA) for transmission …

A mechanical switch that is used to monitor the flow rate & liquid pressure throughout a duct, loop, or system is known as a flow switch. This switch is also known as a flow sensor or flow indicator.

Explore our range of flow switches optimized to fit your industry needs in every way possible. Customize variants according to your requirements.

A flow switch, often called a flow sensor or flow indicator, is a device used to observe the flow rate and pressure of liquids or gases in a duct, pipeline, or system. Its primary role is to constantly monitor the …

Flow switches are mechanical devices designed to trigger an action – such as on/off—based on a chosen setpoint. This, in turn, controls the movement of gas, steam or liquid in a process.

Flow switches are devices that monitor flow and send a trip signal to other devices, like a pump, for protection. These switches can be used for the measurement of gases, liquids, and steam. Flow …
