Background technology
Water meter, as a kind of measurement instrument, is the integrated flow measurement of water mostly.Traditional water meter is mostly Magnetic drive machine
Tool is measured or Magnetic testi electronic measurement：Present is that small magnetic is added on the pointer of original old-fashioned water meter by the way of
Iron, and gathered sensor with outside by wire plus a magneto-dependent sensor and outside collecting circuit board inside water meter
Circuit board is connected, and it reaches the purpose of water measurement amount by detecting the number of turns of indicators turn.But the transmission of its signal is logical
Magnetic field is crossed, thus there is a situation where to be disturbed by external magnetic field, sensor at this moment can all detect constant magnetic signal, is passed
Sensor can not just be counted.Also there is shortcoming simultaneously：1st, there is missing pulse caused by de- magnetic；2nd, magnetic material has demagnetization
Phenomenon, should ensure that magnetic can not be too strong, and caused de- magnetic phenomenon after demagnetization over time is prevented again, there is certain difficulty
Property；3rd, easily by extraneous magnetic disturbance；4th, the magnet installed on impeller, easily the debris in absorption tap water, influences metering.
At present, semicircle tinsel is located at the side of impeller in existing water meter, influences its center of gravity and the stability of metering,
Also the performance of initial-flow is have impact on, when impeller rotates a circle only one of which pulse signal, Meter resolution is not high, while can not
The differentiation of water (flow) direction is carried out, it is necessary to two detection probes and single-chip microcomputer integrated detection circuit using detection probe, so
One adds power consumption and the specific single-chip microcomputer collaboration sensing detection of needs to be accomplished by multiple detection probes.
And water meter has debris because long-time is used and existed, and cleaning water meter is needed to close water valve, and water meter is torn open
Cleaned again after unloading, bother very much, inconvenience is had after the loading in later stage.
