Water Meter Test Bench Automatic Detection Of Various Water Meters

The water meter test bench consists of a workbench, a clamping device, a front, and rear straight pipe section, a flow meter group, a standard gauge, and a drain valve. When the water inlet of the water meter calibration device is connected to a stable pressure water source, the water enters the tested water meter installed on the straight pipe section and then flows into the pre-selected standard volume.
