Energy meter capable of automatic calibration

Abstract

The invention discloses an energy meter capable of automatic calibration, and relates to the field of heat meters. The energy meter comprises a meter body. A connecting shell is fixedly mounted on oneside of the top end of the meter body; a display screen is arranged on one side of the top end of the connecting shell; a reading button is arranged on one side, close to the display screen, of the tripod of the connecting shell; and connecting flanges are arranged on the two sides of the interior of the meter body. A flowmeter is arranged on the side, close to the connecting flanges, of the inner wall of the meter body. A single-chip microcomputer is arranged on one side of the interior of the connecting shell, a partition plate is fixedly installed on the side, close to the single-chip microcomputer, of the interior of the connecting shell, a connecting block is fixedly installed on the side, close to the partition plate, of the interior of the connecting shell, and a guide piece is fixedly installed on one side of the interior of the connecting block. According to the energy meter capable of automatic calibration, the whole device can be automatically calibrated, the precision of the whole device is improved and a better use prospect is realized.

Description

technical field [0001] The invention relates to the field of heat meters, in particular to an automatically calibrated energy meter. Background technique [0002] The heat meter is an instrument for calculating heat. The working principle of the heat meter is to install a pair of temperature sensors on the upstream and downstream pipes passing through the heat-carrying fluid, and the flow meter is installed on the fluid inlet or return pipe (the flow meter is installed on the The position is different, the final measurement result is also different), the flowmeter sends out a pulse signal proportional to the flow rate, a pair of temperature sensors gives an analog signal indicating the temperature, and the totalizer collects the signals from the flow and temperature sensors, using the integrated The calculation formula calculates the heat obtained by the heat exchange system. [0003] There are certain disadvantages in the use of existing heat meters. The existing heat mete...

Problems solved by technology

[0003] There are certain disadvantages in the use of existing heat meters. The existing heat meters will have certain error values ​​when used. The measurement accuracy of the flow rate directly affects the measurement accuracy of the heat meter. When the error of the heat meter is large When it is used, it will cause a certain impact, which is more inconvenient. In the process of use, it will bring a certain impact
