Description
Technical field
The utility model relates to measurement instrument technical field, specifically a kind of electronic measurement water meter of frost-cracking-preventing.
Background technology
Water meter, as a kind of measurement instrument, is that the integrated flow of water is measured mostly.Traditional water meter is mostly the metering of Magnetic drive machinery or Magnetic testi electronic measurement: the mode of present employing is on the pointer of original old-fashioned water meter, add small magnet, and add a magneto-dependent sensor and outside collecting circuit board in water meter inside, sensor and outside collecting circuit board are connected by wire, it reaches the object of water measurement amount by the number of turns detecting indicators turn.But its signal transmission is by magnetic field, so just there is situation about may be disturbed by external magnetic field, sensor at this moment all can detect constant magnetic signal, and sensor just cannot count.Also there is shortcoming: 1, there is the missing pulse that de-magnetic conductance causes simultaneously; 2, magnetic material has demagnetization phenomenon, should ensure that magnetic can not be too strong, and the de-magnetic phenomenon caused after having prevented demagnetization again of long duration, has certain difficulty; 3, extraneous magnetic interference is easily subject to; 4, magnet impeller installed, the foreign material easily in absorption tap water, impact metering.
At present, in existing water meter, semicircle tinsel is positioned at the side of impeller, affect the stability of its center of gravity and metering, also have impact on the performance of initial-flow, when vane rotary only has a pulse signal for one week, Meter resolution is not high, a detection probe cannot be used to carry out the differentiation of water (flow) direction simultaneously, need two detection probe and single-chip microcomputer integrated detection circuit, so just need multiple detection probe to add power consumption and need specific single-chip microcomputer to work in coordination with sensing detection.
Water meter common at present, mostly is wet-type meter, and its counting assembly is immersed in the water work, and its watch glass bears hydraulic pressure, and the transmission of sensor and counter is gear-linked.When using in the winter time, the situation freezing due to cold weather happens occasionally, and particularly in northern China, the water meter installed and used out of doors often causes the bursting by freezing of water gage glass table cover, and water meter cannot normally be used.The freezing main cause of above-mentioned water meter is caused to be that water meter freezes in fact under cold temperature, due to table in water become solid-state from liquid state time, its volume will become large, produce certain bulging force, thus by water meter most, weakness---water gage glass table cover racks, even make other component damage in table, and then affect the normal operation of water meter.Gu how to protect the problems such as water meter can normally use in cold environments to become the focus studied in the industry.
