The cause of the name of the sewage flow meter - focus on microfluidic control technology

Why is the sewage flow meter, because the meter can be used to measure the flow of sewage. Sewage flowmeters are electromagnetic flowmeters, which are currently on the market with customer needs.

Sewage flowmeter is composed of sewage electromagnetic flowmeter sensor and sewage electromagnetic flowmeter converter. It is used to measure the volume flow of various conductive liquids in the pipeline and in the channel.

Sewage flow meter measurement principle is based on Faraday's law of electromagnetic induction. The measuring tube of the flowmeter is a non-magnetic alloy short tube lined with insulating material. Two electrodes are fixed on the measuring tube along the diameter of the pipe through the wall. Its tip is flush with the inside and outside of the lining. When the excitation coil is demagnetized by a two-way square wave pulse, a magnetic field with a magnetic flux density of B will occur in a direction perpendicular to the axis of the measuring tube. At this time, if the liquid having a certain conductivity flows through the measuring tube, the cutting force lines induce an electromotive force E. The electromotive force E is proportional to the magnetic flux density B, and the product of the tube inner diameter d and the uniform flow velocity V is measured. The electromotive force E (flow signal) is detected by the electrode and sent to the converter via the cable. After the converter expands the flow signal, it can display the fluid flow, and can output pulses, simulate current and other signals, and use it for flow control and conditioning.

Sewage flowmeters can be widely used for the measurement of the volumetric flow of conductive liquids in municipal water supply, steel, petroleum, chemical, power, industrial, water conservancy, water resources and other sectors, and are particularly suitable for flow measurement and environmental protection of channels and small rivers. Treatment of sewage measurement.
