Abstract

The invention discloses a low power consumption and wireless communication flow gauge for displaying three kinds of flow information and belongs to the field of wireless communication flow gauges. The problem that an existing flow gauge can not directly display average daily flow values, so that working efficiency of a worker for gauge reading is low is solved. A lithium battery, a single chip microcomputer, a signal shaping module, a flow sensor and a wireless communication module are fixed in an outer shell, a liquid crystal display module is embedded into the outer shell, and the power source signal output end of the lithium battery is connected with the power source signal input ends of the liquid crystal display module, the single chip microcomputer, the signal shaping module and the flow sensor at the same time, and the flow signal output end of the flow sensor is connected with the shaping signal input end of the signal shaping module, the after-shaping flow signal output end of the signal shaping module is connected with the square wave signal input end of the single chip microcomputer, and the data signal output end of the single chip microcomputer is connected with the data signal input end of the liquid crystal display module and the data signal input end of the wireless communication module. The flow gauge is used for the field of flow measurement.

Description

technical field [0001] The invention belongs to the field of wireless communication flow meters. Background technique [0002] The existing flow meter can only display the total flow and one kind of instantaneous flow (m 3 / h), in metering occasions that need to estimate or check the daily average flow value, the staff need to calculate the daily average flow value (m 3 / 24h). The calculation time and the time required to operate the menu is much higher than the time required to transcribe the data, and the calculation results must be carefully checked to avoid data errors, which leads to low work efficiency for the staff. Contents of the invention [0003] The present invention is to solve the problem that the existing flow meter cannot directly display the daily average flow value, which leads to the low work efficiency of the meter reading staff. The present invention provides a low-power wireless communication flow meter that displays three kinds of flow information ...
