Customized electromagnetic flow meter for corrosive liquid is specially designed for water flow measurement of water supply enterprises. It has the characteristics of waterproof, anti-corrosion, anti-interference and lightning protection. The customized corrosive liquid electromagnetic flow meter is designed with a backlight wide screen Chinese LCD, which can display the instantaneous flow and cumulative flow at the same time. The display is intuitive, the functions are complete and practical, the operation is simple and convenient, and the improper operation in the process of use is reduced. In addition, our multi electrode structure further improves the measurement accuracy and eliminates the need for grounding ring at any time, reducing the unnecessary trouble of instrument volume and installation and maintenance.

Confirmation of measuring range of corrosive liquid electromagnetic flowmeter:

The measured medium flow rate of industrial sewage is generally 2 ~ 4m / s. under special circumstances, the low flow rate shall not be less than 0.2m/s and the high flow rate shall not be greater than 8m / s. If the measured medium contains solid particles, the common flow rate shall be less than 3m / s to prevent long-term wear of lining and electrode. For viscous fluid, the flow rate can be greater than 2m / s. a larger flow rate is helpful to automatically eliminate the effect of viscous substances attached to the electrode and improve the measurement accuracy.

Under the condition that the measuring range Q has been determined, the diameter D of the flowmeter can be determined according to the range of the above flow rate V, and its value is calculated by the following formula:

Q=πD2V/4

Q: Flow rate (㎡ / h) d: pipe inner diameter V: flow rate (M / h)

Note: the range Q should be greater than the expected large flow value, and the normal flow value should be slightly greater than 50% of the full scale of the flowmeter.
