Electromagnetic flowmeter measurement principle is based on Faraday's law of electromagnetic induction. Flowmeter measurement tube is a lining insulation of permeability alloys short tube. Two electrodes along diameter direction are through the wall on the measuring tube. The electrode head and the inner surface are approximately flush. Excitation coil pulse of both parties will be in a direction perpendicular to the measuring tube axis to produce a magnetic field of magnetic flux density B. At the same time, if a certain electrical conductivity of the fluid is flowing through the measuring tube, it will cut magnetic induction electromotive force E. Electromotive force E is proportional to the magnetic flux density B, sounding pipe diameter d and the average flow v. Electromotive force E (traffic signal) is detected by electrode and conveyed from the cable to the converter. Converter can display the fluid flow, output pulse and signals by flow signal amplification processing. It is used for flow control and regulation

Throttling coffret - nozzle flowmeter has many advantages, but generally feel pressure pipeline installation on site work is large, also easy to leak, congestion and other issues. Differential pressure transducer made by leaps and bounds in recent years of development, not only the small size, and stable performance, easy to adjust, in use process basically don't need to adjust the zero point. These advantages contribute to a body orifice flowmeter (including orifice plate, the annular orifice, nozzle, etc.) in the development and application. Nozzle flow meter is to measure flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes.
