The waterflow switch is a mechanical/electrical assembly. As it only detects the water flowing in the pipes, the waterflow switch doesn't turn on or off the water. It just sets off the alarms by activating electrical switches. To detect the water's movement, the assembly has a paddle across the inside of the pipe.

In industrial processing, flow is the movement of liquids, steam, and gases through a processing system. Flow rate measurement is used to measure the volume of fluid process media passing through a specific cross-sectional area per unit of time. Monitoring flow rate measurements is essential in controlling the safe movement of fluid within an indus...
As previously stated, flow switches are used to monitor and control the flow rate of fluid within an industrial process system. Automated industrial systems that process fluid media rely heavily on flow switches to ensure safe and optimal flow rates. Flow switches respond to pre-set flow rate levels and perform two functions when those levels are r...
While flow switches and flow sensors both can be used to monitor media flow within a system, the difference between a flow switch and a flow sensor is that a flow sensor can only monitor and display information – flow switches monitor flow and send trip signals and trigger specific actions from machines within the system.
There are a variety of different types of flow switches on the market today – functioning in a variety of different ways – but what all flow switches have in common is that when the flow rate reaches a switch’s set-point, it can either open or close the circuit which triggers an action: whether it’s turning a pump on or off or it’s actuating an ala...
When choosing a flow switch to be used in an industrial system, it is essential that the specifics of that particular type of flow switch matches up with the application criteria of the system. Three of the most popular types of flow switch designs are: Paddle Flow Switches The paddle design flow switch is constructed with a hinged or spring-mounte...
Nov 7, 2024 · A flow switch monitors the flow rate of the media moving through a process line and a pressure switch monitors the pressure within a process line or pipe or vessel. Both pressure switches and flow switches essentially perform the same function, acting as a trigger for a function. They just monitoring different elements of an application.
Jan 6, 2023 · A flow switch is a device used to monitor the flow rate and pressure of liquids, air or other gaseous media through a duct, system or loop. These switches or sensors can be used to monitor flow over a given period of time, or set up to continuously monitor total flow. Technically, a flow meter or indicator may not necessarily be a true flow ...
Feb 26, 2013 · A water flow detector, also known as a flow switch, is an electro-mechanical device designed to send a signal to a local alarm or monitored panel and/or fire department when a continuous flow of water occurs through a fire sprinkler system’s piping. This flow signifies an activated sprinkler head or a leak in the system. A Water Flow Detector ...
Apr 27, 2022 · Fire sprinkler flow switches, which work by monitoring flow or pressure, alert when a sprinkler activates, or damage causes flow or pressure differences. Tamper switches generate a signal when the control valve is closed, ensuring the system works in an emergency. Like any other part of a fire sprinkler system, these switches need regular ITM.

Most water flow switches work by using a paddle - usually a physical one, but sometimes ultrasonic - wired directly to the channel through which water or other liquids will pass. The movement speed of the paddle will indicate the flow rate to the transducer, and the transmitter will, in turn, take this information and convert it to a signal or action.
