Problems solved by technology

This kind of ultrasonic heat meter has many components, which leads to complex structure, high manufacturing cost, difficulty in the installation and disassembly of components, low production efficiency and inconvenient maintenance; in addition, its bracket is placed in the meter body through tight fit , the positioning accuracy is not high, resulting in low measurement accuracy. The bracket is always impacted by fluid during use, and there will be small deviations, which makes the measurement accuracy lower

Abstract

The invention provides a heat meter, which belongs to the technical field of machinery and solves the problems of difficulty in assembly and disassembly, low measurement precision and the like of the traditional heat meter. The heat meter comprises a cylindrical body, wherein the side part of the body is provided with two installing holes communicated with the inside of the body along the axial direction, heat sensors are fixed in the installing holes, reflecting members are also arranged in the body corresponding to the heat sensors and can transmit ultrasonic waves to the heat sensors. The heat meter has the advantages of simple structure, convenience for processing and manufacturing, high measurement precision and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a measuring tool, in particular to a heat meter. Background technique [0002] At present, our country needs heating in winter. In order to save energy and reduce smoke and dust, most areas have centralized heating through the heating network. Heat energy is sold as a commodity for a fee. In the past, it was charged according to the building area, but it is obviously unreasonable to charge the heating fee based on the building area. It should be calculated according to the actual heat energy used by the user, so now the heat meter is used to calculate the heat. The heat meter is composed of a totalizer, a flowmeter, and a temperature sensor. Its working principle is: install a pair of temperature sensors on the upstream and downstream pipes passing through the heat-carrying object, and install the flowmeter on the inlet or return pipe of the fluid. , the flowmeter sends out a pul...
