Method and device for handheld ultrasonic measurement of channel flow speed

Abstract

The invention relates to a method and device for handheld ultrasonic measurement of the channel flow speed, and belongs to the technical field of measurement of the flow speed of river channels or channels. According to the technical scheme, a measuring head (3) comprises an ultrasonic flow speed sensor (7), a flow speed measuring tube (8) and a tail wing (9), wherein the flow speed measuring tube is a tube with the through head end and the through tail end, the ultrasonic flow speed sensor is arranged on the flow speed measuring tube in a matched mode, and the tail wing is arranged on the outer wall of the tail end of the flow speed measuring tube. A host computer (1) comprises a single-chip microcomputer (10), a wireless communication module (11) and a battery (12), wherein the single-chip microcomputer is connected with the wireless communication module and the battery. The host computer is arranged on the upper portion of a measuring rod (2) in a matched mode, and the measuring head is arranged on the lower portion of the measuring rod. According to the method and device for handheld ultrasonic measurement of the channel flow speed, the flow speed sensor is of an ultrasonic type, and is good in stability, the maintenance cost is reduced, the flow speed sensor can work by using the battery, the equipment structure is simplified, and the device for handheld ultrasonic measurement of the channel flow speed can be applied flexibly and conveniently along with continuous improvement of functions of mobile phones and continuous improvement of the data handling capacity.

Description

technical field [0001] The invention relates to a method and device for measuring channel flow velocity with a hand-held ultrasonic wave, which is suitable for the flow velocity measurement of river courses or channels, and belongs to the technical field of flow velocity measurement of river courses or channels. Background technique [0002] At present, the hand-held current meters used in irrigation channels in the water conservancy industry are propeller-type, and the measurement and calculation are mostly manual, and the measurement sensors are mechanical propeller-type. Regular maintenance and calibration are very troublesome, and the requirements for operators are high. The data processing method is outdated, which puts great pressure on the user department. Contents of the invention [0003] The purpose of the present invention is to provide a hand-held ultrasonic method and device for measuring channel flow velocity, which uses a non-mechanical and wear-free ultraso...
