The large size electromagnetic flow-meter was tested to investigate the variation of its error characteristics in the range of low velocity under 0.6m/s using flowmeter calibration system. For the two case of valve opening (100%, 50%), these tests were undertaken three times each for twelve velocity condition from 0.05㎧ to 0.6㎧ with increment of 0.05㎧. |
