Problems solved by technology

[0004] 1. Regardless of the new pipe network or the old pipe network, many of them do not reserve a place for installing large-caliber ultrasonic heat meters, so many sites do not meet the installation requirements, resulting in unstable water fields of the medium measured by the heat meters, thus cause inaccurate measurement
[0005] 2. At present, many heat meters installed on the market have a single metering function. With the implementation of national heat metering and energy saving, people are increasingly finding that a single metering instrument has little effect on energy saving and can only gradually improve awareness. Function, but to have the function of energy saving, it must have the function of measurement and control, and be able to collect pressure or other data
Therefore, it is more and more difficult for the instrument with a single metering function to meet the demand
[0006] 3. Since the heating pipe network is built underground, the heat meters are basically installed in separate underground tube wells. Some areas require stricter construction and more standardized protection, but most of the tube wells are basically not waterproof. Dust-proof, which has caused many heat meters to be soaked in water or covered in dust in a short time after installation. After a long time of use, the heat meters will be unusable or even scrapped

Abstract

The invention relates to a multi-channel multi-functional ultrasonic heat and cold amount meter. The heat and cold amount meter comprises a meter body, a meter head upper cover, a meter head lower cover and a temperature sensor. A glass window is arranged at the top of the meter head upper cover, a circuit board is arranged inside the meter head upper cover, the meter head upper cover is connected with the meter head lower cover through fixing screws, a pipeline extending downwards is arranged on the meter head lower cover, the meter body is in a hollow pipeline shape, and the two ends of the meter body are provided with a water inlet and a water outlet respectively. Transducer installation holes are formed in the two sides of the meter body, ultrasonic transducers are installed in the transducer installation holes, and wire penetrating holes are connected above the transducer installation holes and connected with the pipeline of the meter head lower cover, and the meter body is further provided with a temperature measuring hole and a pressure measuring hole. Through kinds of seal and protection treatment, the protection grade of the product reaches the level of IP68, and the heat and cold amount meter can normally work under kinds of environments and is particularly suitable for occasions of an unstable water field, a severe using environment and a turbid sewage medium environment.

Description

technical field [0001] The invention relates to a multi-channel multi-functional ultrasonic heat-cooling meter, in particular to a multi-functional high-protection-level heat-cooling meter for measuring the flow and quality of a circulating medium in a circulation system using the multi-channel ultrasonic principle. Background technique [0002] With the development of China's heat metering industry, a variety of metering and energy-saving products have been extended, such as "JGJ173-2009 Technical Specifications for Heat Supply Metering": radiator heat distribution meter method, household heat meter method, flow temperature method, On-off time area method, etc., and each measurement method requires a large-caliber ultrasonic heat meter as a node or basis for building settlement or heat allocation. [0003] In recent years, many imported or domestic large-caliber ultrasonic heat meters have been installed on the market, and there are basically the following problems accordin...
