The electromagnetic flow meter is used to measure the volume flow in the conductive liquid and the slurry in the closed pipe. Strong corrosive liquid, such as acid, alkali, salt, etc.. HJ-LDG electromagnetic flowmeter is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries, environmental protection, municipal management, water conservancy construction and other fields.
Selection of electromagnetic flow meter:
1, flow, according to the maximum flow rate to determine the number of large scale flow meter.
2, according to the flow and industrial pipe size, determine the diameter of the flow meter. General selection and pipeline flow meter.
3, according to the characteristics of the measured medium, to select the flow meter of the lining. Such as temperature, corrosive, the pipeline is likely to have negative pressure, etc.. General PTFE, soft rubber, hard rubber, PFA, ceramics, etc..
4, according to the characteristics of the media choose to measure the material of the electrode. Generally have 304, 316, ha's alloy, titanium, tantalum, etc..
5, according to the process pipeline pressure level to choose the flange of the pressure level of the flange.
6, select the protection level, if the sensor is the entire water, need to choose IP68.
Above is the sensor part, there is the transmitter part:
1, according to the requirements of the installation position, determine the choice of one or two.
2, all need what type of output, 4-20 mA signal, Hart, ProfibusPA, FF, etc..
3, whether the need for explosion-proof. Determine the level of explosion-proof.
