The existing detection device for not having special simulation water meter sewage (with suspended impurity) use environment also on the market, water meter need
To use for quite a long time, can just find it is stuck, haze, the disadvantages of flow measurement is inaccurate.The utility model passes through mould
Quasi- water meter sewage is wear-resisting, initial stage of development can influence of the discovery sewage to water meter ahead of time, thus by improve water meter structure or
Use condition ensures water meter service life and precision.By the variation of wear-resisting front and back water meter performance come to optimize water meter performance
And use environment is improved.
The utility model can establish into individual special equipment, can also verify in existing water meter and be changed on board
It makes, realizes that circulation is wear-resisting by connection by-pass water pump circulation circuit and the independent graduated cylinder of increase, to reduce the throwing of whole equipment
Enter the occupancy in cost and space.
