Most widely used is rotary wind type dry-type meter.Traditional dry-type meter is using two-part structure, including impeller driving section
And measurement unit, dry-type meter is because its counting mechanism and fluid to be measured completely cut off, therefore suspended impurity is not influenced in by water, it is ensured that counts
The normal work of mechanism and reading it is clear, while will not be risen below glass caused by table internal-external temperature difference as wet-type meter
Mist or condensation droplet etc. influence meter reading.The impeller portion of dry-type meter and measurement unit are driven by magnetic couplings part
, because of the value that magnetizes of magnetic element, the otherness of magnetic polarity, ensure that water meter initial-flow is small, it is highly sensitive（Initial-flow is less than
8L/h）Measurement unit will be caused not measure or measure in the presence of de- magnetic, mistake portion phenomenon in the high area of flow to be not allowed.Existing rotor is dry
That there are resistance to frosts is poor for formula water meter, and freezing in table causes counter rupture to cause breakage, is frozen quick-fried to which water meter occur, causes to use
Family economic loss；It is not high enough that there is also accuracy classes simultaneously；And existing most area is when charging to user, mainly
Or by the way of manual metering charge, toll collector is needed to visit from door to door work, if encountering family no one need
It to visit again, it is not only time-consuming and laborious, cause working efficiency relatively low, and it is easy to appear pretermission, misreading phenomenon, while this
Mode can also reequip water meter to criminal and steal water resource offer chance, can be caused to Running-water Company and user inestimable
Loss.
