What is the accuracy of the flowmeter for level 1, which is higher than that of the 0.5 stage?
In addition, this precision level refers to the maximum error of the flowmeter. Flowmeter in calibration, usually only mark zero and measurement of these two points. And check the time of the general inspection of five points, that is, full range of 0%, 25%, 50%, 65%, 100%. The error of these five points is less than 1%, both qualified, and allowed to leave the factory. The actual error of these five points may be 0.1%, 0.3%, 0.5%, 0.8% and 0.4%, but the error of the whole machine should be the largest error.
1 meter accuracy level refers to the accuracy of the flowmeter flow range, the actual value of each measuring point and meter display value error is less than 1%, level 0.5 refers to the error value not exceeding 0.5%, of course, the smaller the value the higher the precision.
Then the accuracy of 1 level measurement of the flowmeter in an arbitrary measurement point value and the difference between true flow within plus or minus 1m fand /h. Such as the flow measurement value of 5m /h fand real flow, between 4-6m fand /h.Therefore, the higher the accuracy of the flowmeter, the more accurate the true flow rate. The 0.5 level is more accurate than the 1.
