Problems solved by technology

The resulting problem is that the two different readings are likely to cause users to misunderstand the charging standards of the gas company
[0006] The above two compensation methods both compensate the measurement results of the gas volume, and the measurement accuracy after compensation needs to be retested
The corresponding detection equipment is complex and the detection efficiency is low, resulting in increased production costs
In summary, according to the existing compensation methods, it is impossible to achieve satisfactory results for both gas users and gas companies

Abstract

The invention discloses an intelligent gas meter with temperature compensation. The intelligent gas meter comprises a sampling sensor, a temperature sensor, a pressure sensor, a display module and a power module which are electrical signal connection with a master control module, wherein the master control module comprises a compensation module and a sum advanced payment / withholding module; the temperature sensor / the pressure sensor is used for detecting real-time temperature / pressure data of gas; the sampling sensor is used for converting rotation of a mechanical counter into a pulse electric signal; the master control module is used for receiving the real-time temperature / pressure data and the pulse signal, acquiring corresponding compensation parameters of gas flow under real-time temperature / pressure through the compensation module, transmitting the compensation parameters to the sum advanced payment / withholding module for processing and finally intuitively displaying the compensated gas unit price through the display module. According to the intelligent gas meter, intuitive and accurate gas use unit price and residual sum can be shown to a user, and the condition that the gas metering data corresponding to the working conditions and standard conditions is not unified is avoided.

Description

technical field [0001] The invention relates to the technical field of gas metering, in particular to an electromechanical integrated gas meter metering device, in particular to an intelligent membrane gas meter with temperature compensation function. Background technique [0002] my country's latitude spans a large range, and there are considerable differences in temperature and pressure between different regions. In addition, for different seasons in the same area, the temperature and pressure will also be different. For gas companies, because the volume of gas is closely related to temperature and pressure, and because of the instability of temperature and pressure, they can only formulate a relatively compromise gas settlement standard, that is, the standard condition of gas measurement is, temperature 20 °C, the volume at an absolute pressure of 101.3kPa. However, in fact, membrane gas meters always work in non-standard conditions, so measurement errors will inevitabl...
