Electromagnetic flowmeter meter coefficient, electromagnetic flowmeter because of no pressure damage, relatively low cost advantages, the use of the more common, in addition to the requirements of electromagnetic flowmeter toward more stable, higher accuracy, stronger repeatability and longer life direction development trend.Therefore, how to improve the measurement accuracy of electromagnetic flowmeter has a very important practical significance.
The measurement of electromagnetic flowmeter will be deviated by different substances. Before the original plant, the flowmeter is often calibrated with real flow. However, there are also some deviations in the whole application process of electromagnetic flowmeter for different conditions on site or different substances being measured.
Traffic under the actual condition of standard revised methods, current electromagnetic flowmeter instantaneous flow for Q1, K coefficient of K1, when specific want flow for Q2, we must change the value of the current K coefficient K2 to regulate the flow, to keep changes according to the current K coefficient, assume that the new value K coefficient K2, the flow of K2 is specific to Q2 except in instantaneous flow for Q1, multiplied by the current K coefficient K1: K1, K2 = (Q2 / Q1) *
Example: the electromagnetic flowmeter shows that the current instantaneous flow rate is Q1=54.28. The instrument panel coefficient K1=1.5372 is set inside the electromagnetic flowmeter, and the specific flow rate Q2=60.33 is certified according to the field experience or other methods. Then the desired flow rate can be obtained by changing K1:
That is, K2=(Q2/Q1)*K1= (60.33/54.28)*1.5372=1.7085. Set the obtained K2 into the coefficient column of the instrument panel of the electromagnetic flowmeter again, and replace the original K1 to obtain the new instantaneous flow Q2.
