Stainless steel electromagnetic flowmeter measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity.
Stainless steel electromagnetic flowmeter measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity, the sensor senses a linear relationship between the voltage signal and the average flow rate, so the measurement accuracy is high. Measurement range is wide, can measure a variety of high concentration and high pressure of acidic and alkaline solutions, while the measurement range can be arbitrarily selected. In the selection of stainless steel electromagnetic flowmeter, should pay attention to the following aspects:
1, caliber determination:
Flowmeter use flow rate is best in the range of 0.1-5m/s, at this time the flowmeter caliber can be selected with the user pipe caliber.
2, electric, grounding ring material selection:
Selection of electrical materials, take into account the corrosion resistance of the measured medium, generally higher than the process piping materials a grade. Grounding ring can choose the same material with the electricity, can also choose the same material with the process pipe for the grounding ring. Process piping for metal piping and no edge coating on the inner wall, may not choose the grounding ring.
3, the choice of lining:
The lining material should be selected according to the corrosiveness of the measured medium, abrasive temperature. Polytetrafluoroethylene (PIEE) lining has excellent resistance to strong acid and alkali corrosion performance, it also has a reliable high temperature resistance, high temperature does not deform, does not drop the color edge resistance performance; it also has a non-flick sex, that is, can not be bonded with other substances, smooth surface. Therefore, the measurement of viscosity (such as molasses) or easy to scar the medium (such as alumina) strong corrosive media (such as sulfuric acid, nitric acid, hydrochloric acid, etc.), the medium of higher temperatures or regularly wash the pipeline with the Department of Steam occasions and hygiene requirements of food (such as beer, milk) can be selected PTFE lining.
4, the upper limit of the flow rate selection:
As the diameter, flow rate, flow rate of the three there is a strict functional relationship, so the selection can be based on the following table in the corresponding diameter under the selection of the upper limit of the flow rate value.
