Supersonic measuring sensor for water meter, heat meter and flowmeter and using method of sensor

Abstract

The invention relates to a supersonic measuring sensor for a water meter, a heat meter and a flowmeter and a using method of the sensor, and belongs to the field of acoustic and sensing technologies. A measuring tube segment is composed of a butt clamp body (6) and a guiding beam pipe (7), the guiding beam pipe is arranged at one side of the butt clamp body instead of being arranged at the two sides of the butt clamp body symmetrically or asymmetrically, a sensor installation hole (5) is arranged in the guiding beam pipe, and the supersonic sensor is arranged in the sensor installation hole (5); and the guiding beam pipe is internally provided with a reflector which matches the supersonic sensor. According to the invention, the guiding beam pipe is arranged at one side of the butt clamp body, so that the difficulty in onsite installation is reduced greatly, and an instrument is protected effectively against damage in the installation process; and the measuring tube segment is free of a flange connecting piece, so that the appearance and structure are simple, the installation size is small, no movable parts are included, a dead lock preventive mechanism is not needed, and the measuring sensor can be widely applied to supersonic liquid metering in the water meter, the heat meter and the flowmeter.

Description

technical field [0001] The invention relates to a measurement sensor for ultrasonic water meter, heat meter and flow meter and its use method, especially a flow meter for measuring liquid (gas) flow or liquid heat in a pipeline by using ultrasonic detection technology, which belongs to the field of acoustics and sensing technology . Background technique [0002] At present, the measurement of the liquid flow or heat in the existing pipeline is to install the ultrasonic sensor in the measuring pipe section, and measure the liquid flow or heat in the pipeline through ultrasonic detection technology; the installation form of the ultrasonic water meter, heat meter and flow meter measurement sensor is mainly There are two types: flange connection form and clip-on form. During the use of these two installation forms, the measurement sensor has the following problems: the measurement sensor installed in the flange connection form, because it involves the operation space of the flan...

[0002] At present, the measurement of the liquid flow or heat in the existing pipeline is to install the ultrasonic sensor in the measuring pipe section, and measure the liquid flow or heat in the pipeline through ultrasonic detection technology; the installation form of the ultrasonic water meter, heat meter and flow meter measurement sensor is mainly There are two types: flange connection form and clip-on form. During the use of these two installation forms, the measurement sensor has the following problems: the measurement sensor installed in the flange connection form, because it involves the operation space of the flange connection, Therefore, its structure is complex, its shape is large, its installation length is long, its operation is inconvenient, and its cost is high; the measurement sensor installed in the form of a clip needs to lock the rotatable ultrasonic sensor after installation, and there are moving parts, installation In addition, the cost is high; for example: Chinese patent number: 201420273092.6, patent name: a card-type ultrasonic fluid flow measurement device, which is a measurement sensor installed in the form of a clip
