Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0013] An ultrasonic heat testing device mainly includes a temperature sensor 1 and a temperature sensor 2 2, a pair of ultrasonic transceivers 31, 32, a controller unit 6, and a display instrument 7.

[0014] The temperature sensor one 1 and the temperature sensor two 2 have the same structure, but the installation positions are different, the temperature sensor one 1 is located at the outlet of the water supply, and the temperature sensor two 2 is located at the return water of the water supply. For a community or a user group composed of multiple users, a plurality of unit water supply pipes 41 are set up from the water supply main pipe 4, and then the return water of each user is recovered from the unit return water pipe 51 and enters the return water main pipe 5 for recovery. When measuring the heat usage state of a single user, a ...

Abstract

The invention mainly discloses an ultrasonic wave heat testing device which comprises a temperature sensor I and a temperature sensor II, a pair of ultrasonic transceivers arranged in medium, a controller unit for processing process data, and a display apparatus, wherein the temperature sensor I and the temperature sensor II are respectively arranged at a water outlet position and a water return position; the temperature sensor I, the temperature sensor II and the ultrasonic transceivers are connected to the input end of the controller unit, and the controller unit which is provided with calculation program in the internal part calculates according to the received data at the input end, and feeds back the result to the display apparatus. According to the ultrasonic wave heat testing device, heat (cold) quantity consumed by a user in a heat supply (cold supply) system is accurately measured, and the ultrasonic wave heat testing device is stable to use.

Description

technical field [0001] The invention relates to the technical field of measuring fluid heat, in particular to an ultrasonic heat testing device. Background technique [0002] The heat meter is a key instrument and an important basis for charging by heat in the heating system, and its technical indicators such as measurement accuracy and working stability are very important. The amount of heat (cold) consumed by users in a central heating (cooling) system with hot (cold) water as the medium is related to the flow of hot (cold) water and the value of water supply and return. With the promotion of the installation of heat meters in civil buildings with central heating and the implementation of household metering and charging work in our country, the heat meters for household metering have also ushered in a very good development period. There are mechanical and ultrasonic heat meters, and the ultrasonic heat meter is one of the development directions of the heating system. At ...
