HW split electromagnetic flow meter installation precautions

Abstract: HW split electromagnetic flowmeter installation precautions information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Precautions for installation of HW split electromagnetic flowmeter The sensor of the split electromagnetic flowmeter should be installed vertically, and the fluid flows from bottom to top to meet the condition that solid and liquid are in a mixed state. The reason is that there are solids in the medium (silt, small stone particles, etc. For more flowmeter manufacturers to select models and prices, you are welcome to inquire. The following is the details of the HW split electromagnetic flowmeter installation precautions article. HW split type Precautions for the installation of electromagnetic flowmeter The sensor of the split electromagnetic flowmeter should be installed vertically, and the fluid flows from bottom to top to meet the mixing state of solid and liquid. The reason is that if there are solids in the medium (silt, small In addition, if there are fish and weeds in the pipeline, the fish swimming in the pipeline will cause the output of the flowmeter to swing back and forth; the weeds hanging near the electrode will also swing back and forth. It will cause the output of the flowmeter to be unstable. Set a metal filter at the upstream inlet of the flowmeter to prevent fish and weeds from entering the measuring tube. The split electromagnetic flowmeter prevents negative pressure pipeline settings and improper operation will cause negative pressure in the sensor. When closing the upstream and downstream valves of the flowmeter at the same time, if the temperature of the fluid is higher than the air temperature, it shrinks after cooling, so that the pressure in the pipe will be in danger of forming a negative pressure. The negative pressure will cause the lining and the metal conduit to peel off, causing the electrode to leak. Add a negative pressure prevention valve near the flowmeter, and open the valve to connect to atmospheric pressure to prevent negative pressure from being generated in the sensor. When a vertical pipe is connected downstream of the split electromagnetic flowmeter, if the upstream valve of the flow sensor is used to close or adjust the flow, the sensor measures Negative pressure will be formed in the pipe. In order to prevent negative pressure, it is necessary to add back pressure or use downstream valves to adjust and close the flow. Split electromagnetic flowmeters have appropriate maintenance space, and large-diameter flowmeters are often installed in instrument wells for pipeline installation and wiring. For the convenience of inspection and maintenance, appropriate space needs to be reserved. For the convenience of observation, wiring and maintenance, the installation of the instrument should be at a certain height from the ground to facilitate cleaning and installation.
