Joint Test FMC240_ Electromagnetic Flowmeters _ Infrared Touch Models

The working principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The two electromagnetic coils at the upper and lower ends in Figure 2 generate a constant or alternating magnetic field. When a conductive medium flows through the electromagnetic flowmeter, an induced electromotive force can be detected between the left and right electrodes on the wall of the flowmeter tube. The magnitude of this induced electromotive force is proportional to the flow velocity of the conductive medium, the magnetic induction intensity of the magnetic field, and the width of the conductor (the inner diameter of the flowmeter measuring tube). The medium flow rate can be obtained through calculation. CN1 product features: infrared sensing touch, lightning protection output: current (4~20mA), pulse, frequency; Accuracy: of measured values; 0.5% (flow rate ≥ 0.5m/s) measurement value of 0.5% 2mm/s (flow velocity ＜ 0.5m/s)
