Influence of adding a self-made filter to the water inlet of a large-diameter water meter on the error of water representation value
In order to study the influence of water meter error caused by the installation of filter screen upstream of the disaster water meter and the blockage of the filter screen, a simulated filter screen blocking experiment was carried out. Characteristics, filter screen and blocking degree have different changing rules for the error characteristic curve of water meters of different calibers. The influence of the filter screen on the error of the water meter is within an acceptable range, and the accurate measurement of the water meter, in addition to the measurement characteristics of the water meter itself, also The influence of installation conditions needs to be considered, and it is necessary for water supply companies to conduct similar simulation tests according to their own water meter types and installation conditions to study the applicability of different installation conditions to ensure the accuracy of measurement.
In short, it is recommended to install and use the filter correctly to avoid unnecessary economic losses.
