5CP-LDESeries instrument selection
◆Range confirmation
The general industrial electromagnetic flowmeter measures the flow rate of the measured medium2～4m/sIn special circumstances, it is advisable to,zuiThe low flow rate should not be less than0.2m/s，zuiThe height should not exceed8m/sIf the medium contains solid particles, the commonly used flow rate should be less than3m/sTo prevent excessive friction between the lining and electrodes; For viscous fluids, the flow velocity can be selected to be greater than2m/sA higher flow rate helps to automatically eliminate the effect of viscous substances attached to the electrode, which is beneficial for improving measurement accuracy.
within the rangeQUnder the determined conditions, the above flow rate can be usedVThe range determines the diameter of the flowmeterDThe size of is calculated by the following formula:
Q=πD2V/4
Q:Flow rate (㎡)/h）D:inner diameter of pipeV: Flow rate（m/h）
Range of electromagnetic flowmeterQShould be greater than expectedzuiA large flow rate value, while a normal flow rate value is slightly larger than the full-scale scale of the flow meter50It is appropriate.
