The digital water meter field calibrator is used to measure the indication error of small-diameter water meters on pipelines. The instrument uses a high-precision volumetric water meter as the standard meter and uses a photoelectric sensor to detect the rotation speed of the standard meter. The D LCD display displays the cumulative flow rate and instantaneous flow rate of the standard meter respectively. It has the advantages of high testing accuracy, clear readings, small size, light weight, portability, and ease of use. This instrument is widely used in the tap water industry and large and medium-sized industrial and mining enterprises for on-site testing of water meters in use.
