Description

Technical Field

[0001] The utility model relates to the technical field of heat measurement, in particular to a large-caliber dual-channel ultrasonic heat meter. Background Art

[0002] Ultrasonic heat meter is an instrument that measures the flow rate and displays the heat energy released or absorbed by water flowing through the heat exchange system by ultrasonic method. It measures the physical quantities of heat carrier flow and inlet and outlet temperatures through two sensors, and then compensates and integrates the density and enthalpy values ​​to obtain the calorific value. It is a mechatronic product based on microprocessors and high-precision sensors.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: most of the existing large-caliber dual-channel ultrasonic heat meters are equipped with a filter box mechanism for filtering liquids, but the filter box mechanism has an independent disassembly and assembly mechanism, and the connecting pipe is connected to the threaded sleeve of the external pipe through a thread. Whenever the blockage is to be cleared, the connecting mechanism between the pipes must be disassembled first, and then the disassembly and assembly mechanism of the filter box must be disassembled to clear the blockage of the pipe and the filter screen. The two sets of independent disassembly and assembly mechanisms make the process more complicated and affect the efficiency of clearing blockage, which is in urgent need of improvement. Therefore, we propose a large-caliber dual-channel ultrasonic heat meter. Utility Model Content
