High-precision two-way metering electronic water meter

Abstract

The invention discloses a high-precision two-way metering electronic water meter which comprises a water meter shell, a water meter core and a control circuit, wherein the water meter core comprises an impeller, an impeller shaft and a fixing rack; a strong magnet is arranged at the middle part of the impeller; the control circuit comprises a lithium battery, an induction coil, a first Hall sensor, a second Hall sensor, a display screen, a master control chip, a storage unit, an electromagnetic damping control circuit and a wireless charging management circuit; positions of the induction unit,the first Hall sensor and the second Hall sensor all correspond to the position of the strong magnet on the impeller; the strong magnet is capable of cutting the induction coil. According to the high-precision two-way metering electronic water meter disclosed by the invention, mechanical drive is replaced with an electronic circuit, the metering precision of the water meter is improved, the energy loss is reduced, and the phenomenon that metering cannot be performed during power-off can be avoided. Moreover, self-rotation of the water meter is avoided, and the functions of measuring at high accuracy, realizing low power consumption, avoiding maintenance for a long time and preventing strong magnetism are realized.

Description

technical field [0001] The invention belongs to the technical field of water meters in measuring instruments and meters, and in particular relates to a high-precision bidirectional metering electronic water meter. Background technique [0002] Water meters are instruments used to measure water flow, and are widely used in many fields such as homes, factories, and offices. The types of water meters can be divided by the measurement principle, the common types are: [0003] a) Mechanical water meters: Measuring sensors, calculators and indicating devices are water meters with mechanical principles and structures, mainly speed-type water meters and volumetric water meters. [0004] b) Mechanical water meters equipped with electronic devices: mechanical water meters with complete structures are retained, and water meters with electronic devices are added on this basis, mainly including IC card water meters and remote water meters. [0005] c) Electronic water meters: Electroni...

Problems solved by technology

[0017] Most of the existing water meters adopt mechanical structures. Due to the mechanical transmission and mechanical adjustment structure, the production capacity of the water meters is greatly limited; at the same time, this kind of water meters requires professional and technical personnel to install and debug during production testing, fault detection and on-site maintenance. , higher requirements for production testers, resulting in lower efficiency of installation, commissioning, and maintenance
