Water meter test bench DN15-50

Description

The Water meter testing bench is the necessary measure instrument for the test and repair of water meter in metrological service, Water meter manufacture, Water supply company, industrial and mining establishments.
The tester bench is made of stainless steel materials; The surface is treated with polishing.
Clamp equipment and drain machine is controlled by four-way reversing valve; The water flow rate is adjusted by copper case stainless steel core ball valve, it has high accuracy, the structure is compaction, long life, easy operate and maintain.

3. Structure and working principle
The water meter tester bench is composed by work desk, clamp equipment, front and back straight pipe, flowmeter, standard volume container, drain water valve.
After the water from the steady sources come into the enter place of tester bench, the water will come into the tested meter in straight pipe, and then come into the choosed standard volume container, compare the reading number between tested meter and standard volume container, and get the error of testing water meter.)
