SKLD series electromagnetic flowmeter measuring appliance shaping
¡ô measuring range scope confirmation
Generally the industrial used electromagnetic flowmeter was measured that the medium speed of flow take 2~4m/s as suitable, in the peculiar circumstance, the lowest speed of flow should not be smaller than 0.2m/s, highest should not be bigger than 8m/s. If in the medium includes the solid particle, the commonly used speed of flow should be smaller than 3m/s, prevents the lining and electrode's excessive friction; Regarding the viscous fluid, the speed of flow may choose is bigger than 2m/s, the great speed of flow is helpful to eliminates sluggish which automatically on the electrode adheres to stick cohere the function, is advantageous in the enhancement measuring accuracy.
In measuring range Q had determined under the condition, then acts according to above speed of flow V scope decision flowmeter caliber D the size, its value calculates based on the equation below:
Q=¦ÐD2V/4
Q: Current capacity (©O/h) D: Pipeline inside diameter V: Speed of flow (m/h)
Electromagnetic flowmeter's measuring range Q should be bigger than the estimate the maximal-flow size, but the normal flow rate take is bigger than the flowmeter full scale scale division suitably slightly 50 as.
