Description
Affiliated technical field:
The utility model relates to a kind of sensor for embedded ultrasonic flowmeter, is to utilize ultrasonic detecting technology to measure fluid flow, heat in the pipeline, belongs to acoustics, sensor technical field.
Background technology:
At present, existing ultrasonic flowmeter generally all is made of mounting base, survey sensor with sensor, main mounting means on pipeline and existing problems are as follows: 1, plug-in installation, when adopting this kind mode to install, at first need accurate measuring channel external diameter and pipeline wall thickness size, determine the installation site of sensor then according to external diameter and wall thickness dimension.The shortcoming of this kind mounting means is: it is bigger influenced by on-the-spot pipeline ovality precision and pipeline physical dimension, wall thickness, and above parameters is difficult for accurately measurement when installing; If in the 2. on-the-spot pipeline water is arranged, under the situation of not arrheaing, to install and must use special-purpose drilling tool, operation is complicated, and requires operating personnel that certain technical merit is arranged; 3. this kind mounting means requires the erecting stage that certain operating space must be arranged so that install and maintenance in the future.2, pipeline section type mounting means when adopting this kind mode to install, because of sensor has been fixed on the pipeline section body, gets final product so only the pipeline section body is connected with bolt with on-the-spot pipe flange when installing.The shortcoming of this kind mounting means is: 1. this kind mounting means only is applicable to small-bore instrument; The processing cost of larger caliber instrument, transportation cost, installation cost are all higher, and large-diameter pipe segment body operation difficulty when installing, and the set-up time is long.If 2. the scene is the situation that primary tube segmentation instrument is installed of replacing, so new instrument must be identical with meter run that is replaced and flange size, otherwise can't install, and is unfavorable for the interchangeability of product.3, built-in type mounting means when adopting this kind mounting means, must accurately be measured in pipeline earlier, determines the installation site according to institute's survey pipeline inside dimension parameter then.This kind mounting means advantage is that influenced by the pipeline ovality less, and can precisely determine the installation site at pipe interior, but its shortcoming is: 1. this mounting means only is suitable for large diameter pipeline, and installation personnel can carry out fitting operation in pipeline; Need when 2. installing accurately to measure and determine the installation site, complicated operation, set-up time be long, the technical merit of installation personnel own is had relatively high expectations; 3. this kind mounting means instrument can not be used the powered battery mode.
The utility model content:
The utility model purpose provides a kind of sensor for embedded ultrasonic flowmeter, and simple installation, applied widely, workable solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
A kind of sensor for embedded ultrasonic flowmeter comprises fixed mount and some to survey sensor, some sensor is fixedly installed on the fixed mount, constitute an one-piece construction with fixed mount, every pair of sensor comprises the emission sensor and the receiving sensor of mutual coupling, has oneself fixing position relation between emission sensor and the receiving sensor.
The size of fixed mount determines that according to the size of pipe laying fixed mount is fixedly mounted in the pipeline.
The logarithm of said sensor can be a pair of or how right without limits, determines as required.
The installation method of above-mentioned sensor for embedded ultrasonic flowmeter on pipeline, comprise following steps: 1. the pipeline upper shed of ultrasonic flowmeter with sensor is installed at needs, 2. ultrasonic flowmeter is put into the pipeline precalculated position with sensor integral body, and be fixed in the pipeline; 3. the opening on the closed conduct.
Ultrasonic flowmeter is known with the mode of sensor overall fixed in pipeline, and fixation gets final product, for example: adopt welding, bonding, mode such as be threaded.
The utility model is with separate survey sensor in the every pair of survey sensor in the prior art, change an one-piece construction of fixed position relation into, can in one-piece construction, arrange one or more pairs of survey sensors, arrange that according to the measurement of correlation standard-required each is to survey sensor.Only need be fixed on the general frame that survey sensor is housed in the pipeline during installation and get final product, need not loaded down with trivial details installation process, this also is the fundamental difference place of the present invention and existing plug in sensor, plug in sensor is that part enters in the pipeline, the pipeline outside keeps a part always, and the present invention is integral body, all is placed in the pipeline.
The beneficial effects of the utility model: compare with the prior art scheme, the utility model installation process is convenient and swift, the installation accuracy height, applied widely, adopt the utility model to install and when detecting flow, can simplify installation process greatly, save the set-up time, guarantee the instrument measurement precision, also widened the fitting limit of sensor simultaneously; The utlity model has rational in infrastructure, technology is advanced, characteristics such as easy for installation, applied widely, can be widely used in the measuring technique of ultrasonic flowmeter, calorimeter.
