Please tell me the accuracy level of the water meter
Measurement level is divided by the demarcation of the water gauge and the minimum flow rate to characterize the sensitivity of the water meter. The old rules are graded according to A, B, C and D, and the D level is the highest requirement. New procedures, dosage, process ratio (Q3/Q1) to replace the original level of measurement, the ratio of at least 20 options, the greater the ratio, the higher the requirements, the greater the difficulty of manufacturing. The Q3 and Q3/Q1 values of the water meter are determined by the manufacturer according to the market demand, and must be clearly marked on the water meter. When the water meter is checked, the flow point can be chosen according to the value indicated on the meter.
Accuracy level and measurement level of water meterThe accuracy level and measurement level of water meter are two different concepts. The accuracy grade provides the indication error limit of water meter, and the 2 stage indicates the maximum indication value of water meter, and the error can not exceed 2%. The new procedure has 1 meter water meters, but it must be marked on the water meter.
