Description

Technical Field

[0001] The utility model relates to the technical field of thermal metering equipment, in particular to urban thermal metering equipment. Background Art

[0002] In the winter in northern my country, heating is required. In order to save energy and reduce smoke, most areas have centralized heating through heating networks. However, since heat energy is sold as a commodity, it must be charged. However, since residents have not installed heat meters in their homes, they have to charge according to the building area for the time being. However, it is obviously unreasonable to charge heating fees according to the building area. It should be calculated according to the actual heat energy used by the user.

[0003] Therefore, the instantaneous flow rate of hot water at this moment must be measured, and then it must be multiplied by the temperature difference to get the kilocalories of heat released by the hot water at this moment. The user's consumed calories can then be added together at any time using the automatic accumulation method, and the total amount of calories consumed for a full month is the total amount of calories consumed that month. Existing thermal metering equipment is usually an integrated design, and the sensor needs to be taken out as a whole for replacement, which is inconvenient. At the same time, the pipeline dissipates heat during operation, and the temperature inside the equipment rises. Long-term use may damage the internal electronic equipment and reduce its service life. For this reason, we propose an urban thermal metering device. Utility Model Content
