Accurate heat metering not only helps heating enterprises to reasonably allocate energy and reduce operating costs, but also provides users with fair heating billing basis and promotes energy saving and efficient use.

[0003] In the current market, there are various types of heat consumption metering devices for heat distribution network. The traditional built-in heat metering device often needs to cut off the heat distribution network during installation, which not only greatly increases the construction difficulty and cost, but also interferes with the normal operation of the heat distribution network during installation, and even causes heating interruption. In addition, since it directly contacts with the medium in the pipe, it is easily plagued by problems such as medium corrosion and impurity blockage, which further reduces the measurement accuracy and shortens the service life of the device.

[0004] To solve the above problems, external connection type heat consumption metering device emerges as the times require. The commonly used external connection type metering device usually installs two ultrasonic transducers on the outer wall of the pipeline, and cooperates with a temperature detection device to measure heat. Among them, the two ultrasonic transducers are responsible for detecting the flow of the heat distribution network, the different distances between the two ultrasonic transducers correspond to the detection of the flow of the pipe network with different diameters, and the temperature detection device is used to detect the temperature of the pipe network, and then the heat of the pipe network can be calculated according to the heat formula.

[0005] However, the existing external connection type metering device has many deficiencies in practical application. At present, the ultrasonic transducers need to be fixed respectively, and the installation process is relatively complicated. When the length is adjusted according to the pipe network with different diameters, the two ultrasonic transducers need to be disassembled respectively, and the overall disassembly flexibility is poor, which cannot quickly and effectively adapt to the heat distribution network with different diameters, which to some extent limits the popularization and application of the external connection type heat metering device, and also affects the convenience and accuracy of heat metering of heat distribution network, so a heat consumption metering device of external connection type of heat distribution network is needed to solve the above problems.
