• Confirm range
General industrial electromagnetic flowmeter measured medium flow rate 2 ~ 4m / s is appropriate, in exceptional circumstances, the minimum flow rate should not be less than 0.2m / s, the maximum should not exceed 8m / s. If the medium contains solid particles, commonly the flow rate should be less than 3m / s, to prevent excessive friction lining and the electrodes; for viscous fluid flow rate can choose more than 2m / s, the larger the flow rate can help effect on the electrode attached automatically eliminate viscous material, helping improve measurement accuracy.
Q has been determined in the range of conditions, you can determine the size of the diameter D of the flow meter based on the velocity V of the range, the value calculated by the following formula:
Q = πD2V / 4
Q: flow rate (/ h) D: pipe diameter V: velocity (m / h)
Range of electromagnetic flowmeters Q should be greater than the expected maximum flow rate, and the normal flow value slightly larger than the 50% full scale of the meter is appropriate.
