Abstract

The invention is suitable for the technical field of flow metering and provides a water flow metering method and device. The method includes: acquiring a voltage value output by a flow speed sensor; determining water flow speed corresponding to the voltage value according to a preset voltage-flow speed conversion algorithm; integrating the water flow speed, and updating water flow information according to an integration result. By placing the flow speed sensor in a to-be-measured water flow area, when water flow passes the flow speed sensor at a certain flow speed, a voltage value having a certain corresponding relationship with the flow speed is generated, the water flow metering device acquires the voltage value, the water flow speed corresponding to the voltage value is acquired by calculating according to the preset voltage-flow speed conversion algorithm, and the water flow information is updated according to integration of the water flow speed, so that the objective of water flow metering is achieved, and the problem that existing water flow metering technology is low in accuracy and highly subject to influence of manufacturing process.

Description

technical field [0001] The invention belongs to the technical field of data measurement, and in particular relates to a water flow measurement method and a device thereof. Background technique [0002] Water fee, as an important data in daily life, the accuracy of its measurement will directly affect the national and even global users. The water flow rate is used as a relational parameter to determine the water fee, and its accuracy will also determine the accuracy of the water fee measurement. The existing measurement method of water flow mainly needs to drive the water flow to rotate when the water flows through the gear, and determine the flow velocity of the water flow at that moment by the speed of the water flow rotation, and then measure the water flow to obtain the water flow. However, this method is greatly affected by the manufacturing process. If the friction between the gear and the shaft is too large, the water flow will be less; if the gap between the gear and...
