Water Meter Test Bench

Gravimetric Water Meter Test Bench DN15-DN25

Model: MJ3210 Series

Water meter test bench DN15-25 is designed for water meter manufacturers to calibrate cold water meters for mass production or R&D purpose. It is gravimetric method and adopts latest technology (LabVIEW image-processing software, machine view, etc) for decreasing water supply and increasing high efficiency. The test bench is for verification and calibration of meter and pressure withstanding check, all the testing process is automatically controlled by PC. The test bench has 2 lines (12+12). One line (12 testing positions) is on testing, the other line is to unload tested meters, load new meters and ready for testing. It is high efficiency and very popular in water meter manufacturers and government calibration centers.
