+86 16712288222Accuracy is how close the measured value is to the true value. In a flowmeter, this means the distance between the output of the flowmeter and its calibration curve. This is expressed as a percentage, for example ± 1%. This means that any given reading may have an error of 1% above or below the calibration curve. Generally, it can be said that the lower the percentage, the more accurate the instrument Yes. However, it also depends on the specification of FS (full scale) or Rd (reading).
Repetition accuracy of mass flowmeter
Under the same conditions, repeatability will produce the same results. In other words, the flowmeter should produce the same reading when operating under the same variables and conditions. This is also expressed in ± percent.
Although accuracy is usually the focus of the measurement community, repeatability is the basis of accuracy. Without high precision, it can have high repeatability, but without high precision, it cannot have high precision.
It doesn't help if the watt hour meter sometimes only has high accuracy once. If your data is unreliable and you get different numbers in the same environment and settings, none of these numbers can be completely correct.
