Abstract
The water tower, the water well, the reservoir and so on will be in water supply system's common facility, the water level monitoring will cause its water level will maintain at automatically certain position, will satisfy the water used the request. The water level monitoring control unit's research design regarding the enhancement water supply system automation level, the enhancement production efficiency has the important meaning.
The paper uses the piezoresistive sensor sensation water level the change through A/D transformation and single chip machine system, realizing the precision to be high, intellectualization, volume exquisite water level supervisory system. Follows the intellectualized measuring appliance's design concept, uses in the modern measuring appliance design the component solution, makes the metering circuit perform reliably, the structure to be simple, the power loss is low. In inlays the measuring appliance software uses the algorithm the measuring technique and the computer technology will unify, will enable the measuring appliance to have functions and so on automatic zero setting, calibration, software filter. Paper design's water level monitoring meter online survey timeliness is good, the communication reliability is high, is suitable the surface to be broad, its performance and the domestic and foreign similar products performance quite, can satisfy the market requirement.
