Showing Results For: Flow Switches
Flow switches are an essential component of fluid control systems, used to monitor the flow of liquids or gases and trigger automatic actions based on predefined flow rates.
A flow switch is a device that senses the flow rate of fluids, such as a liquid or a gas, and activates an electric switch based on a preset flow rate. The switch can be used to turn on or off a pump, an alarm, or any other device that depends on the presence or absence of fluid flow.
There are two main types of flow switches, mechanical and electronic. Mechanical flow switches use a paddle, vane, or piston to detect flow and activate a switch. Electronic flow switches use sensors and circuits to monitor flow and trigger an output signal. Each type has several variations and subtypes, depending on the application and specific requirements.
Flow switches are used in various industries, including HVAC, water treatment, food and beverage, chemical processing, pharmaceuticals, etc. Some typical applications of flow switches include:
Flow switches offer several advantages over other types of flow sensors, including:
In conclusion, flow switches are a vital component of many fluid control systems that monitor and maintain the flow of liquids or gases. With a range of types and applications, flow switches offer simplicity, cost-effectiveness, versatility, and reliability.
