Abstract

The invention belongs to the technical field of metering meters and provides a water meter and a metering circuit thereof. The circuit comprises a control chip, a display unit, a power module and a graphene flow sensor, wherein the power module is connected with the control chip, the graphene flow sensor is used for detecting water flow and outputting a flowing speed signal to the control chip, the control chip generates and stores water use data according to the flowing speed signal, and the display unit is connected with the control chip and used for displaying the water use data. The circuit is simple in structure, few electronic devices are adopted, the reliability is high, and the cost is reduced. In addition, data collection of frozen water amount on a settlement date of a user is easy to achieved, and technical guarantee is provided for comprehensive implementation of ladder-like water price.

Description

technical field [0001] The invention belongs to the technical field of water meter measurement, and in particular relates to a water meter and a metering circuit thereof. Background technique [0002] Water resources are essential resources for human survival, and saving water has become our consensus. At present, many cities in my country have begun to implement tiered water prices to guide residents to save water and alleviate the shortage of water resources. To implement tiered water prices, it is necessary to obtain the daily frozen water volume on the user's settlement day, which puts forward certain requirements for the user's water meter. [0003] At present, traditional water meters generally adopt mechanical water meters. This kind of water meter needs to be equipped with a character wheel direct reading device. The mechanical structure is complex, the accuracy is poor, the reliability is poor, and there is no function of freezing water consumption. Although the ex...
