Electronic water meter

Abstract

The invention discloses an electronic water meter. The electronic water meter comprises a water meter base meter, a metering and sampling component, a data processing unit, a data storage unit and a data transmission unit. The metering and sampling component comprises a plurality of magneto-dependent sensors, the water meter base meter comprises a base and an annular magnet, the annular magnet is installed on the end portion of a rotating shaft of an impeller of the water meter base meter, the magneto-dependent sensors are all arranged on one face, opposite to the annular magnet, of the base and located over the annular magnet perpendicularly, and the magneto-dependent sensors are used for converting sensed magnetic pole converting information of the annular magnet into electric signals. The output ends of the magneto-dependent sensors are all connected with the input end of the data processing unit, the data processing unit is connected with the data storage unit, and the data processing unit is further connected with the data transmission unit. The electronic water meter has better temperature stability, a wider metering range, higher reliability, and a more convenient and fast management and maintenance method.

Description

technical field [0001] The invention relates to a water meter, in particular to an electronic water meter. Background technique [0002] More than 90% of the vast majority of water meters used in daily life are mechanical water meters. With the continuous deepening of the system reform of China's urban water supply companies, various water supply companies have gradually realized the importance of accurate flow meter measurement and intelligent management. Therefore, the small flow measurement capability and accuracy of the water meter itself needs to be improved. Defects of traditional water meters: 1. Waste of water resources. Due to the limited accuracy of measurement, when the water flow is relatively small, the leakage loss is large and it is difficult to measure accurately; 2. Ordinary smart water meters use reed switch measurement methods, which are flexible on the one hand. On the other hand, the measurement accuracy is limited; 3. The means of copying and managemen...

Problems solved by technology

Defects of traditional water meters: 1. Waste of water resources. Due to the limited accuracy of measurement, when the water flow is relatively small, the leakage loss is large and it is difficult to measure accurately; 2. Ordinary smart water meters use reed switch measurement methods, which are flexible on the one hand. On the other hand, the measurement accuracy is limited; 3. The means of copying and management are backward, because the mechanical water meters are all manual meter reading, which not only increases the management cost, but also is not conducive to the control of on-site meters; 4. Difficult to maintain. Most of the meters installed on site need to read the data once a month or two. In case of meter failure, it is not easy to find and difficult to monitor.
