Electromagnetic Flowmeter FAQs
Q: What is the main purpose of the electromagnetic flowmeter?
Answer: Electromagnetic flowmeters can be used to measure the volume flow of conductive fluids in closed pipes. It is widely used in flow measurement and control in industrial and agricultural production processes such as petrochemical industry, iron and steel metallurgy, water supply and drainage, water conservancy irrigation, water treatment, environmental protection sewage measurement and control, papermaking, medicine, food and other industrial and agricultural production processes.
Q: What is the difference between a flow meter and a water meter?
Answer: In addition to measuring the instantaneous flow of the liquid, the flowmeter can also measure the cumulative flow, and the flow data can be output to the secondary instrument, which is convenient for statistics and management. These are all things that water meters cannot do.
Q: Why is there no data or inaccurate measurement of the flow meter for measuring sewage for a long time?
A: It may be that the electrode is covered with sludge or damaged. Regular maintenance is recommended.
Q: Why does the value jump after it is connected on site?
Answer: It may be because the nearby electromagnetic interference is too strong, and no grounding treatment has been done.
Q: What is the reason why there is no reading in the flow meter measurement on site?
Answer: Medium reasons: insufficient water content, insufficient electrical conductivity, too small flow rate or full tube, etc.
Q: What causes the measured value to be inconsistent with the output value?
Answer: Dissatisfied pipe, too low flow rate, damaged converter, over-range and other reasons may cause the measured value to be different from the output value.
Q: Why does the flowmeter for measuring sewage take a long time, and there will be no data or inaccurate measurement?
A: It may be that the electrode is covered with sludge or damaged. Regular maintenance is recommended.
Q: Why is there a traffic display after connecting it?
Answer: The pipeline is not filled with liquid, or the liquid contains air bubbles, subjectively think that the liquid of the tube pump has no flow, but there is actually a small flow, and the reasons for the liquid (such as poor uniformity of liquid conductivity, electrode pollution, etc.).
Q: What matters should be paid attention to in installation?
Answer: It is best to install it indoors, avoid exposure to sunlight and dripping, avoid excessive temperature difference, keep away from flame, avoid installing at the pump inlet, install horizontally, avoid air bubbles and open downwards, avoid negative pressure and dissatisfied pipes, avoid vibration, reasonable support, the sensor cannot be used as a load support point, etc.
