Electromagnetic flowmeter sewage treatment process is mainly through the biological oxidation, flocculation, precipitation and other processes to achieve the purpose of sewage purification, in each stage requires a certain amount of meter to measure. In the sewage industry, electromagnetic flowmeters are as small as DN15 and as large as DN2000 calibers.
Electromagnetic Flowmeters Large-diameter flowmeter sensors in wastewater plants are mostly installed underground, so it is recommended to choose IP68 (dust-proof submersible). Usually electromagnetic flowmeters require all the following requirements for the installation site.
1) When measuring the mixed phase fluid, select the place that will not cause phase separation; when measuring the two-component liquid, avoid installing in the downstream where the mixing is not uniform; when measuring the chemical reaction pipeline, install it in the downstream of the reaction fully completed segment; Meet the straight pipe before and after the paragraph is not less than 5D and 2D;
2) Avoid as much as possible negative pressure in the measuring tube;
3) Choose a place with little vibration, especially for integrated type instruments;
4) Avoid large electric motors, large transformers, etc. nearby to avoid electromagnetic interference;
5) It is easy to realize the place where the sensor is grounded separately;
6) Avoid high concentrations of corrosive gases in the surrounding environment as much as possible;
7) Avoid direct sunlight as much as possible
