Electromagnetic flow meter for measuring sulfuric acid in water supply equipment

This case comes from (Tianhai pressure vessel): This equipment is controlled by the frequency conversion control cabinet to directly control the submersible pump, and the submersible pump outlet is directly pressurized to the user's pipe network. The frequency conversion control cabinet adjusts the speed of the submersible pump to adapt to the user's constantly changing amount of sulfuric acid. Compared to air pressure water supply equipment, the equipment has a simple structure, small footprint, stable operation and low initial investment. Due to the storage device, water is cut off when there is a power failure. When the user does not use sulfuric acid or sulfuric acid with a small flow rate, the pump will generate a large amount of reactive power to maintain the pipe network pressure, and the overall energy consumption will be about twice as high as that of the pneumatic type water supply equipment.

Two pumps are installed in front of the tank, and the pump is controlled by a frequency conversion control cabinet. An electromagnetic flowmeter is installed at the water outlet of the pump to measure the flow of sulfuric acid. Because the user sometimes needs to immediately stop and stop the equipment, the amount is small, and electromagnetic changes are added. After the flow meter, it can effectively measure the amount of persulfate, and can more accurately and timely shut down the equipment.

The measuring tube of the electromagnetic flowmeter is a non-magnetic alloy short tube lined with an insulating material. Two electrodes pass through the pipe wall along the pipe diameter and are fixed on the measuring pipe. When the coil is energized, a magnetic field having a magnetic flux density of B will be generated in a direction perpendicular to the axis of the measuring tube. Therefore, it is more appropriate to use an electromagnetic flowmeter to measure the sulfuric acid flow.

Friendship reminder: Buy flow meter devices do not want to be cheap, to choose a good fit for their own equipment, generally consider the use of the environment, etc., do not blindly choose because of cheap.
