Flow switches are essentially flowmeters. But there are some differences between the two, which can be understood from the following aspects.

1, a measurement, a non-measurement is also known as the flow rate switch, can only start flow or no flow signal can not play the role of measurement, like the electronic/thermal conduction type on the market is the water flow switch, can not be measured. Flowmeter: The flowmeter can be measured, such as electromagnetic flowmeter, ultrasonic flowmeter, turbine flowmeter, impeller flowmeter and so on can be measured.

2, use different

Flow switch, when the flow in the pipeline reaches the value of the set switching point, sends out an action to cut off or connect the peripheral circuit, only used to detect whether the flow reaches the set point.

Flowmeter: is used to detect real-time flow rate, can be measured from 0 to maximum range continuously. Can be real-time reaction flow changes! If you connect the flow meter to the control system, you can also set up alarm points on the system!

3. Different functional characteristics

Flow switch, as the name suggests, has switch function, and according to the size of the flow to decide whether to switch or not, is the role of intermediate relay, some flowmeters with alarm switch can also realize the function of flow switch, but relatively speaking, the price is higher.

Flowmeter covers more categories, some only show instantaneous flow of small flowmeter, low price, installation is also convenient, very suitable for process occasions to do reference use, require better accuracy, record information comprehensive or to choose advanced flowmeter.

Flow switch and flow meter are widely used in daily life, such as fire flow switch, clamp type flow switch, air conditioning flow meter, electromagnetic flow meter and so on. You can choose to buy according to your own project use.
