The need for intelligent electromagnetic flowmeter calibration requires liquid flow rate should be stable, if it directly from the water pipe or pump the water to the calibration, the liquid flow rate is certainly unstable, so for calibration is a very difficult thing. So the use of a highly stable level to provide water. First, the highest figure to the right of the valve is opened, the water from the diagram to the left tank, liquid level reaches the highest position of the valve, the water will flow from the pipes A sink through the valve. And the horizontal length of the pipe A is relatively long. A height in the horizontal plane can be approximated that an area of ??relatively large pool of high-quality child electromagnetic flowmeters picture, as opposed to measuring the diameter of the electromagnetic flowmeter. A liquid level has remained at such height, so that a flow rate is stable. Such sensors out of the signal is relatively stable. Integrated electromagnetic flowmeter measurement principle: Measuring principle arslde type integrated electromagnetic flowmeter is based on Faraday's law of induction conductive liquid cutting magnetic field lines, generating EMF conductor in a magnetic field, the EMF e is: e = kbvd wherein: when the average velocity d ----- inner diameter of the measurement pipe section of the flow measuring instrument constant k ----- b ----- v ----- measuring magnetic induction within the pipe cross-section, the conductive liquid flowing at a speed v of the magnetic field perpendicular to the flow direction, the flow of conductive liquid induces a, the induced voltage signal by two or more direct contact with the liquid and the average velocity is proportional to the voltage of the high-quality electromagnetic flowmeter quotes electrodes detected and sent via intelligent processing converter through a cable, then lcd display or converted into a standard signal output 4 ~ 20ma and 01khz.
