The emphasis on environmental protection and sewage treatment will involve sewage flow meters, how much sewage is generated, how much sewage is purified, and so on. Actually, sewage flow meters are also electromagnetic flow meters. So, what are the main things that need to be done when installing and using electromagnetic flow meters?
There are many advantages of sewage electromagnetic flowmeter, such as: measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity; For example, measuring the flow components inside the tube, without pressure loss, with lower requirements for straight pipe sections. Adaptability to slurry measurement;
Although there are many advantages to electromagnetic flow meters for sewage, choosing the right flow meter is a good start, but it is more important in installation and use.
1. Environmental selection: Be sure to stay away from magnetic fields.
2. Location selection: The installation location must ensure that the pipeline is always filled with the measured liquid.
3. Installation of pipeline straight section: The sensor installation pipeline straight section should be 5D after D. That is to say, there should be 10 times the length of the pipeline straight section at the inlet and 5 times the length of the pipeline straight section at the outlet
4. Flow control valves and regulating valves: Pay attention to flow control and adjustment of valves in different states.
The application range of sewage electromagnetic flowmeter is very wide, including chemical industry, water conservancy, water administration, etc., but the primary condition is that the conductive liquid, the correct lining material, the correct electrode material, and the appropriate flowmeter should be selected.
