Product Details

Working principle of electromagnetic flow meter measurement is based on the Faraday law of electromagnetic induction. Measurements of the flow meter tube is lined with insulating material of a non-magnetic alloy spool. Two clicks along the diameter through-wall fixing on the measuring tube. The electrode head is flush with the lining inner surface. Field coil by waves when pulsed excitation by both parties, will be measured perpendicular to the pipe axis direction produces a magnetic flux density of the magnetic field b. At this point, if you have some electrical conductivity of fluid flows through the measuring tube, cut magnetic lines of induction electromotive force. Electromotive force e is proportional to the magnetic flux density B, measure the inside diameter d and the product of the mean velocity v. Electromotive force e (traffic signal) checked out by electrodes and cables to the converter. Converter after the traffic signal will be amplified, to display fluid flow and energy output pulse, analog current signals for flow control and the flow adjustment. E=KBdv Type: E-- for signal voltage between the electrodes (v) B-- magnetic flux density (t) d-- measuring tube diameter (m) v-- average flow velocity (m/s) K, d is a constant, due to magnetizing current is constant, b is constant, the E=KBdv, is proportional to the signal voltage and volumetric flow Q E-. And volume flow rate sensor signal voltage e Q into a linear relationship. Therefore, as long as the measure to determine the flow rate Q, this is the basic operating principle of electromagnetic flowmeter. By E=KBdv today, the measured flow of medium temperature, density, pressure, conductivity, liquid-solid two phase media of liquid and solid ingredients than parameter does not affect the measurement results. As for the axisymmetric flow flow state as long as it meets (such as laminar or eddying flow) does not affect the measurement results. Thus volume flowmeter Electromagnetic Flowmeter is a real. For manufacturers and users alike, just use plain water after the actual calibration of measuring volume flow of the fluid any other to the point, without the need for human and remediation. This is electromagnetic flowmeter to highlight advantages, is not found in any other flow meters. Measuring tube and block parts of inactivity. So there is little pressure loss and extremely high reliability.
