| Structure and Features:︰ | The water meter test bench is made up the platform, clamps, back and front pipe, flow counter group, standard measuring instrument and the outlet valve.
When the inlet is connected with the stable water source, the water will get to the standard measuring instrument through the straight pipe. Compare the value of the checked water meter with that of the standard measuring instrument, the valve error that the water meter reads will be acquired.
