Abstract
The utility model relates to an intelligent diaphragm gas meter utilizing a pressure sensor, which comprises a microcontroller and a measuring room and is characterized in that the pressure sensor is installed in the measuring room and connected with the microcontroller. The pressure sensor is installed in the gas meter, the microcontroller acquires signals of the pressure senor and carries out pressure compensation of measure, due to the fact that the volume and the pressure of gas have close relation, the pressure sensor is utilized to compensate the measure, and gas flow measure is more accurate.
Description
Technical field
The utility model relates to a kind of intelligent diaphragm gas meter of adopts pressure sensor.
Background technology
Gas meter, flow meter is a kind of metering device that uses combustion gas that is used to measure.Common gas meter, flow meter connected mode is that an end connects gas pipeline, and the other end is connected on the kitchen range, and when the user used combustion gas, combustion gas got into kitchen range from gas pipeline through gas meter, flow meter, connecting tube; General diaphragm gas meter is through being arranged on the mechanical type meter in the gas meter, flow meter to the metering of using combustion gas; Be that mechanical counter of gear train drive that combustion gas promotes to be arranged on through gas meter, flow meter the time in the gas meter, flow meter is beated; When combustion gas stops to flow; Counter also stops to beat, and finally is to confirm what of gas consumption through the numeral that shows on the counter.But present gas meter, flow meter is a volume metering, and its degree of accuracy is limited.
The utility model content
The purpose of the utility model provides a kind of intelligent diaphragm gas meter of adopts pressure sensor, can flow metering be compensated through the signal of pressure transducer, makes metering more accurate.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of intelligent diaphragm gas meter of adopts pressure sensor comprises microcontroller and measuring room, and its special feature is, in the said measuring room pressure transducer is installed, and this pressure transducer is connected with said microcontroller.
Wherein microcontroller is a single-chip microcomputer.
The utility model has been installed pressure transducer in the inside of gas meter, flow meter; Gather the pressure compensation that pressure sensor signal measures by microcontroller; Because gas volume is relevant with the sunset at pressure sunset of gas; Therefore adopts pressure sensor compensates metering, can make the gas flow metering more accurate.
Description of drawings
Accompanying drawing 1 is the logic theory block diagram of the utility model;
Accompanying drawing 2 is the control flow chart of the utility model.
Embodiment
Come the utility model is done further detailed explanation below in conjunction with accompanying drawing; As shown in Figure 1; A kind of intelligent diaphragm gas meter of adopts pressure sensor comprises microcontroller and measuring room, and pressure transducer is installed in the measuring room; And this pressure transducer is connected with said microcontroller, and wherein microcontroller is a single-chip microcomputer.
Gather pressure sensor signal and tongue tube pulse signal by microcontroller, compensate calculating, and the flow that calculates is presented at LCD MODULE and is kept at memory module, can make the gas flow metering more accurate.
