E+H split electromagnetic flowmeter installation precautions

What matters should be paid attention to when installing the E+H split electromagnetic flowmeter

The prominent feature of the E+H split electromagnetic flowmeter is that the meter head can be separated from the sensor to view the flow rate. The length of the split line can be appropriately increased according to the needs of the site. For example, if there are many pipelines in a steel plant, if the flow meter is installed in the middle, it will be inconvenient for workers to view, so a split electromagnetic flow meter is a good choice. 1. E+H split electromagnetic flowmeter avoids improper use of air pressure pipe settings, which will cause air pressure in the controller. When closing the gate valves upstream, middle and upstream of the flow meter at the same time, if the temperature of the two-phase flow is higher than the weather. Shrinking after cooling causes the risk of air pressure being generated by the water pressure outside the tube. Air pressure causes the lining to separate from the alloy conduit, causing electrical leakage. 2. Add an air pressure avoidance valve around the E+H split electromagnetic flowmeter, and open the gate valve to connect to atmospheric pressure to avoid air pressure in the controller. When there is a vertical pipeline connected to the upstream of the split electromagnetic flowmeter, if the upstream and downstream gate valves of the flow sensor are used to close or adjust the reserve, a negative pressure will be generated outside the measuring pipe of the controller. In order to prevent air pressure, add back pressure or use an upstream valve to adjust and close the allowance. 3. The E+H split electromagnetic flowmeter has an appropriate protection space. Therefore, the large-size flowmeter is installed in the meter well to facilitate pipeline construction, wiring, and regular inspection and protection. Appropriate space must be left. In order to facilitate observation, wiring and maintenance, the instrument should be installed at a certain height from the ground to facilitate cleaning and installation. 4. If the E+H split electromagnetic flowmeter is installed in a flammable or explosive place, explosion-proof measures should be taken, especially the split line should be made into an explosion-proof shielded line diagram, so as to avoid the occurrence of danger. 5. If the E+H split electromagnetic flowmeter is installed in an anti-corrosive place, the split wire should be made into an anti-corrosion shielded wire. 6. Since there are many pipelines and branches in the steel plant, the pipelines should be avoided so that it is easy to see the on-site metering flow rate.
