Novel water resource flowmeter

Abstract

The invention provides a novel water resource flowmeter, and belongs to the technical field of flowmeters. The novel water resource flowmeter comprises a to-be-measured flow pipe, the to-be-measured flow pipe is provided with a front-back clamping mechanism and two sets of up-down clamping mechanisms, and the front-back clamping mechanism is connected with the two sets of up-down clamping mechanisms through a connecting mechanism; an ultrasonic flowmeter body is arranged on the front-back clamping mechanism, and the surfaces of the front-back clamping mechanism, the up-down clamping mechanisms and the ultrasonic flowmeter body are sleeved with protection mechanisms; The front-back clamping mechanism comprises a front clamping plate and a rear clamping plate. the whole flow meter is reasonable in structural arrangement and ingenious in conception, the flowmeter can be installed on a to-be-measured pipeline without stopping flow and cutting off the pipeline and only needs to be installed outside the pipeline through clamping, and due to the characteristic of movable measurement, the whole novel water resource flowmeter can be suitable for evaluating and measuring the flow condition of a pipe network. Meanwhile, the whole novel water resource flowmeter can be matched with to-be-measured flow pipelines with different pipe diameters through the clamping mechanism, the clamping effect is good, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of flow meters, and in particular relates to a novel water resource flow meter. Background technique [0002] The English name of the flowmeter is flowmeter, which is defined by the National Science and Technology Terms Approval Committee as: an instrument that indicates the measured flow rate and (or) the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure fluid flow in pipelines or open channels. Flowmeters are divided into differential pressure flowmeters, rotameters, throttling flowmeters, slit flowmeters, volumetric flowmeters, and electromagnetic flowmeters. flowmeter, ultrasonic flowmeter, etc. [0003] When installing and using the above-mentioned flowmeters for liquids, most of the flow tubes to be measured need to be installed with a stop-flow cut-off. Among them, the clamp-on ultrasonic flowmeter does not need to be installed with a stop-flow cut...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of water resource flowmeter, aiming to solve the problem that most flowmeters in the prior art need to stop the flow pipe to be measured and install it, while the existing external clip-on ultrasonic flowmeter is aimed at different The clamping mechanism of the pipeline cannot be adapted, and it is necessary to redesign and manufacture a clamping structure that matches the outer diameter of the pipeline to clamp and fix it, which only increases the production cost. Some use binding belts to match the flowmeter to clamp the pipeline Although the setting increases its versatility, the clamping effect is very poor and other problems
