ZN-LDW seriesSubmersible electromagnetic flowmeterThe measurement of flow rate is not affected by changes in density, viscosity, temperature, pressure, and conductivity of the flow rate. The sensor induced voltage signal is linearly related to the average flow rate, resulting in high measurement accuracy. ZN-LDW seriesSubmersible electromagnetic flowmeterThere is no obstruction in the measuring pipeline, so there is no additional pressure loss. There are no movable parts in the measuring pipeline, so the sensor has a long lifespan. The straight pipe section required for the sanitary electromagnetic flowmeter sensor is relatively short, making it easy to install. Only the inner lining and electrode of the sanitary electromagnetic flowmeter sensor are in contact with the measured liquid. As long as the electrode and inner lining materials are selected reasonably, they can resist corrosion and wear. The bidirectional measurement system can measure forward and reverse flow rates.

Submersible electromagnetic flowmeterCorrect wiring:
① ZN-LDW seriesSubmersible electromagnetic flowmeterThe excitation cable can use YZ medium-sized rubber sheathed cable, which has the same length as the signal cable
② ZN-LDW seriesSubmersible electromagnetic flowmeterSignal cables and other power cables must be strictly separated and cannot be laid in the same pipe, parallel, or twisted together. They should be separately threaded in steel pipes.
③ ZN-LDW seriesSubmersible electromagnetic flowmeterThe signal cable and excitation cable should be kept as short as possible, and excess cables should not be coiled together. The excess cables should be cut off and re welded. When the cables enter the sensor electrical interface, they should be made U-shaped at the port to prevent rainwater from penetrating into the sensor.
④ ZN-LDW seriesSubmersible electromagnetic flowmeterThe connection between the excitation cable and the converter of the split type electromagnetic flowmeter is completed with dedicated wiring, and the converter and external connection are the same as that of the integrated electromagnetic flowmeter.
