Briefly describes the electromagnetic
flow meter according to different working condition requirements of power supply mode electromagnetic
flowmeter is a kind of flow meters are widely used in industrial field, according to the requirements of different working condition, the power supply will also be different.
Next we will talk about the electromagnetic flowmeter for different condition requirements of power supply.
More than a, 220 v power supply current application teaching, general industrial site has 220 v power supply, as long as according to the requirements for installation of the flow meter, electricity can work on.
The 220 v power supply electromagnetic flowmeter can make one-piece can also split type.
If distance meter and control room, as far as possible choose 220 vac electromagnetic, because the cable is too long, the signal attenuation, requires an external 220 vac power source voltage.
Second, 24 v power supply is mainly used in industrial field are not allowed to use ac or consider using low voltage direct current (dc) from the aspects of safety, or match; flow totalizer. especially
By integrating instrument for electromagnetic flowmeter for power supply, can only choose to 24 v.
Under the condition of the flow meter and control room far distance, can choose 24 VDC electromagnetic, so do save power supply, cable laying when walking bridge, also need not add clapboard;
Third, the batteries used at the moment is not too much, mainly for some live without any power supply.
At the same time also has a fault alarm function, flow is set up and down and alarm function, positive and negative phase flow switching function.
But the price is quite high.
Different working conditions, that is the power supply and introduces the way of electromagnetic flowmeter, hope to be of help.
