It controls the flow rate and force of liquids, air, or other gaseous means by a duct, system, or loop. These flow switches or sensors can be used to control flow at a given period. It is also set up to control total flow always. Expertly, a flow meter or indicator may not certainly be a proper flow switch. If the tool only records and shows data, it is mostly called a meter or indicator. In many cases, they will set off effects on other system elements like pumps, such as setting the flow rate and pressure to the required and planned levels. This will then be a proper flow switch.

How does a Flow Switch work?

To learn how a flow switch works and what it does, just go through its working. It helps draft the core elements that make up a standard switch or sensor of this sort.

Several kinds will hold a paddle or magnetic set joined to a circuit and put in the channel by which liquid or gas is passing. This paddle is removed or turned by any element that is flowing by. Then it sends a sign coming back to a trivial element known as the transducer.

The transducer takes this new signal from the paddle and carries it on to a transmitter in a simple format. In turn, the transmitter holds this reading on a preset of parameters and works on any sign or action is needed to set the behavior of elements and tools elsewhere.

How are Flow Switches used?

To know how a flow switch is used, you first want to know what job the switch is meant to work in the precise system you're talking about. The vast majority are meant to work fully automatically unless damaged. So if you know how to use a flow switch, you should know how to resolve the issue when these switches are not working. That will rely fully on the part it plays in a given system.

Flow Switches on boilers

Flow switches on boilers can be seen in both water and gas pipelines. They're usually fixed for water channels to guard the boiler against working in low states. Gas boiler flow switches are mostly used to stop the boiler from firing before any formation of gasses has been released by coolers by the pipe.

Flow Switches for pumps

A pump flow switch is usually fitted to stop the pump from working dry when there is less water supply. As water pumps can fast heat or become damaged by constant running in no-flow states, flow switches usually briefly shut down the pump's energy when there is not much liquid in it.


Choosing the right kind, size, voltage, and use of flow switch for the exact service. Fitting these switches is vital if they are to work correctly in the task you want them to work.

With many varieties of products available, it can be complex to make the best choice. Here we are always present to clear all your confusion. We will guide you and help you opt for the best tool that you desire to buy for your precise working. For more details contact us.
