Ultrasonic water meter

Abstract

The invention relates to the technical field of water meters. The problems that most of existing ultrasonic water meters adopt lithium batteries or charging modes; power supply, regular replacement isrequired in use; the environment-friendly and energy-saving requirements cannot be met; the working efficiency is also reduced; the device comprises a detection pipe, a flange, an ultrasonic water meter and a generator, a wiring hole is formed in one side wall of the ultrasonic water meter; a main pipe is arranged at the lower end of the ultrasonic water meter, a fastening nut is connected between the ultrasonic water meter and the main pipe, wire pipes are arranged on the two sides of the main pipe, sensors are connected in the wire pipes, a detection pipe is arranged at the lower end of themain pipe, and an adjusting nut is connected between the main pipe and the detection pipe. The ultrasonic water meter has the beneficial effects that by arranging the generator, the rotating shaft and the rotating wheel, automatic power generation in the ultrasonic water meter is achieved, the environment-friendly and energy-saving requirements are met, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to an ultrasonic water meter. Background technique [0002] Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change of velocity when the ultrasonic sound beam propagates downstream and countercurrent in water, analyzes and processes the flow velocity of water to further calculate the flow of water, and its characteristics are: low initial flow velocity , wide range ratio, high measurement accuracy and stable operation, no moving parts and no blocking elements inside, not affected by impurities in water, long service life, complete output communication functions, meeting various communication and wireless networking requirements. [0003] Most of the existing ultrasonic water meters use lithium batteries or rechargeable batteries as the power supply, and they must be replaced regularly during use. If the power supply is exhausted...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the shortcomings of the existing technology, an ultrasonic water meter is proposed, which solves the problem that most of the existing ultrasonic water meters use lithium batteries or rechargeable batteries as the power supply, and they must be replaced regularly during use. If the power supply is exhausted, the ultrasonic water meter will detect It is prone to errors and even causes internal damage, which not only fails to meet the requirements of environmental protection and energy saving, but also reduces the problem of work efficiency
