Double-clock detecting method for flowmeter

Abstract

The embedded water meter recognizer involves a verification method of a flow meter. There are 6 main steps in total. Whether the value is within the range of the error value to verify whether the meter to be tested is qualified. Compared with the existing technology, this method can quickly and accurately verify whether the flow meter is qualified by measuring and calculating the weight obtained by the electronic scale per unit time and the conversion of the flow rate of the meter to be tested, which solves the problems of long time-consuming verification and water consumption .

Description

technical field [0001] The invention relates to a verification method of a flow meter. Background technique [0002] At present, the single-clock verification method is commonly used in the verification of flow meters. For example, through traditional photoelectric acquisition technology, the two pulse signals of the standard meter and the meter to be tested are measured in the same time range. The measurement error is usually within one pulse. Between the two pulses, according to the currently commonly used 0.2-level flow meter calculation, in order to ensure the measurement accuracy, the number of pulses that need to be collected in a measurement process must be more than 10,000, that is, for water meters with relatively low accuracy, at least 1000 pulses are to be collected. According to the calculation of DN15 water meter, the pulse number of the impeller of the water meter can be collected into the system through the laser probe. Generally, the minimum pointer of the w...
