Abstract
The utility model belongs to the technical field of acoustics and sensing, in particular to a measuring pipe section for an ultrasonic water meter or heat meter. The utility model adopts a technical scheme that: the measuring pipe section comprises sensor mounting seats (2), ultrasound probes (3) and a measuring straight pipe (5), wherein the sensor mounting seats are arranged on the measuring straight pipe; the ultrasound probes are arranged in the sensor mounting seats; the measuring straight pipe is at least provided with a pair of sensor mounting seats; and each pair of arranged ultrasoundprobes are matched with each other. The measuring pipe section is characterized in that the center line of the sensor mounting seats, namely the mounting direction of the sensor probes, is at a certain angle rather than parallel to an ultrasonic wave transmission and receiving direction. The measuring pipe section has the advantages that: the ultrasonic measurement angle alpha is reduced to a maximum degree; measurement acoustic path length is prolonged; ultrasonic measurement conditions are improved; and the measurement accuracy of instruments is improved effectively. In addition, the mounting direction of the ultrasound probes can be changed, so the assembly and maintenance are more convenient and quick, and labor capacity is improved.
Description
Affiliated technical field:
The utility model belongs to acoustics, field of sensing technologies, and particularly a kind of Ultrasonic water meter, calorimeter are with measuring pipeline section, and it is the special-purpose pipeline section of converter that utilizes fluid flow in the ultrasonic detecting technology metering pipeline, is applicable to the metering of fluid flow, heat in the pipeline.
Background technology:
At present, domestic existing pipeline is with the transducer of Ultrasonic water meter, calorimeter, and with reference to accompanying drawing 1, it is measured, and the used pipeline section of passage is general main to be made of flange 1, sensor mount pad 2, ultrasonic probe 3 and measurement straight tube 5.In use there is following problem in this pipeline: according to the measuring principle of ultrasound wave instrument, ultrasonic measurement angle α more little (it is big more promptly to measure the sound travel length M) helps improving ultrasonic measurement accuracy and instrument measurement precision more; But measure in the pipeline section existing, because the ultrasonic probe installation direction is parallel with ultrasonic emitting (reception) direction, therefore under the certain situation of measuring tube segment length L, be subjected to the restriction of processing of sensor mount pad and ultrasonic probe fitting operation, the reducing of ultrasonic measurement angle α (promptly measuring the sound travel length M increases) difficulty is bigger, finally cause influencing ultrasonic measurement accuracy, reduce the instrument measurement precision.
The utility model content:
The utility model purpose provides a kind of Ultrasonic water meter, calorimeter transducer with measuring pipeline section, improves the accuracy of an instrument and reliability, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: Ultrasonic water meter, calorimeter transducer comprise sensor mount pad, ultrasonic probe and measurement straight tube with the measurement pipeline section, the sensor mount pad is arranged on to be measured on the straight tube, ultrasonic probe is arranged in the sensor mount pad, at least on the measurement straight tube, a pair of ultrasound wave mount pad is set, the every pair of ultrasonic probe that is provided with mates mutually, its special feature is the center line of sensor mount pad, the installation direction of sensor probe just, with ultrasonic emitting, receive direction at an angle, be uneven.
A pair of mutual coupling ultrasonic probe both can be installed on the same measurement pipeline section, also many ultrasonic probes to mutual coupling can be installed simultaneously, said mutual coupling is meant the coupling of sensor ultrasonic emitting, acceptance.
Preferable mode is: the installation direction of sensor probe is vertical with ultrasonic emitting, receive direction.
The utility model also is provided with flange, is arranged on the two ends of measuring straight tube, is convenient to measure pipeline section and is connected with pipeline.
The utility model changes ultrasonic probe installation direction and ultrasonic emitting (reception) direction into vertical relation (or inclination certain angle) by parallel relation; The change back is compared with background technology (equal bore, equal flange, equal length, equal ultrasonic probe) under equal condition, can reduce ultrasonic measurement angle α significantly and increase to measure sound travel length, improves ultrasonic measurement accuracy and instrument measurement precision; Satisfy Ultrasonic water meter, the calorimeter converter measurement requirement of measuring pipeline section.
The utlity model has rational in infrastructure, technology is advanced, measuring accuracy is high, characteristics such as easy for installation, overcome the shortcoming of prior art, can be widely used in the measuring technique of Ultrasonic water meter, calorimeter, can reduce ultrasonic measurement angle α to greatest extent and increase to measure sound travel length, improve the condition of ultrasonic measurement, effectively raised the measuring accuracy of instrument.In addition, the change of ultrasonic probe installation direction makes installation and maintenance more convenient, quick, has improved labour productivity.
