How is the flow switch selected?
According to the existing pipe diameter selection, there are contact type and electromagnetic type
So what should we pay attention to when selecting?
1, how much power supply voltage is DC or AC general DC 24V, AC 220V
2, power consumption for the number of VA, then you need to choose the election.
3, the output mode, there are often open and normally closed.
4, contact capacity, which should be important. General flow switch by setting the flow, you can display whether the flow reaches the set value.
There are many kinds of flow switch types, the following brief introduction to several common flow switch: 1, a baffle (can show the flow) 2, the float 3, the metal rotor (can show the flow) 4, viscosity compensation 5, Rotary type (can show the flow) 6, thermal flow switch (can show the flow) 7, can also be used plug-in electromagnetic flow meter.
