Split electromagnetic flowmeter is mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines. Including acid, alkali, salt and other highly corrosive liquids. This product is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, papermaking and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.Installation notes:The sensor of the split electromagnetic flowmeter should be installed vertically, and the fluid should flow from bottom to top to meet the condition that the solid and liquid are in a mixed state. The reason is that the solid matter (sand, pebble particles, etc.) in the medium is prone to precipitation. In addition, if there are fish and weeds in the pipeline, the movement of fish in the pipeline will cause the output of the flowmeter to swing back and forth; the back and forth swing of the weeds hanging near the electrode will also cause the output of the flowmeter to be unstable. A metal filter is installed at the upstream inlet of the flow meter to block fish and weeds from entering the measuring tube.Separate electromagnetic flowmeter prevents negative pressure from setting the pipeline improperly, which will cause negative pressure in the sensor. When the upstream and downstream valves of the flowmeter are closed at the same time, if the temperature of the fluid is higher than the air temperature and then shrinks, the pressure in the pipe will be in danger of forming a negative pressure. The negative pressure causes the lining to peel off from the metal conduit, causing electrode leakage.Add a negative pressure prevention valve near the split electromagnetic flowmeter, and open the valve to connect to the 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, a negative pressure will be formed in the measuring pipe of the sensor. In order to prevent negative pressure, it is necessary to add back pressure or use a downstream valve to adjust and close the flow.Separate electromagnetic flowmeters have adequate maintenance space. Large-caliber flowmeters are often installed in meter wells. For the convenience of pipeline installation, wiring, inspection and maintenance, appropriate space needs to be reserved. For the convenience of observation, wiring and maintenance, the instrument should be installed at a certain height from the ground to facilitate cleaning and installation.
