Abstract
The invention discloses a gas meter measuring device capable of correcting errors in real time and relates to a measuring device. The gas meter measuring device comprises a seal shell, a measuring core, a sampling sensor, a master control circuit board, a CPU (central processing unit) and a protecting shell. The measuring core is disposed inside the seal shell. The sampling sensor is disposed on one side of the seal shell. The master control circuit board and the CPU are disposed on the outer side of the sensor. The protecting shell is disposed on the outer side of the master control circuit board and the CPU. An error correcting function formula is built in the master control circuit board and the CPU. The gas meter measuring device has the advantages that the gas meter measuring device is provided with the technology of error real-time correcting, product precision is increased, the gas meter measuring device can satisfy measuring ranges of a G1.6 gas meter, a G2.5 gas meter and a G4 gas meter, error correcting after long-term gas use is achieved, namely an error curve can be corrected in an overall manner when set volume of the gas meter is used or the gas meter is used for a set period of time, and overall negative-bias of the diaphragm gas meter after long-term use can be avoided.
Description
Technical field
What the present invention relates to is a kind of measuring apparatus, is specifically related to a kind of gas meter, flow meter measuring apparatus of round-off error in real time.
Background technology
The metering of domestic gas is divided into mechanical type diaphragm gas meter, integral intelligent diaphragm gas meter, electronic gas table according to intelligent degree.The mechanical type diaphragm gas meter measures by the combustion gas of gas meter, flow meter by the epithelium of certain volume amount, when the metered flow of gas meter, flow meter is different, has different errors, and along with flow is larger, error is more negative, and this gas meter, flow meter measurement technology has been used decades, and technology is relatively stable reliable.But due to the impact that is subject to different manufacturers production technology and designing technique, according to different flows, being divided into 3 models, is respectively G1.6, G2.5, G4, and measures range is respectively (0.016～2.5) m
3/ h, (0.025～4) m
3/ h, (0.04～6) m
3/ h, according to national standard, error range is generally ± and 1.5%.The integral intelligent diaphragm gas meter is on the basis of mechanical type diaphragm gas meter, increases control circuit board, completes the purpose of checking meter and charging, and metering section is still completed by the mechanical type diaphragm gas meter, and meter characteristic is identical with the mechanical type diaphragm gas meter; More before the electronic gas entry is ultrasonic wave gas meter, this gas meter, flow meter intelligent degree with respect to the mechanical gas table is higher, metering is also to gather computing by electron device to form, but because it is subject to the impact of turbulent air flow, also there is certain error, and ultrasonic wave gas meter is applied to domestic gas metering is not also very ripe, service time is also not long, does not also obtain the checking of time.
(error refers to the difference between measured value and true value, it is gas meter, flow meter and the standard scale metering difference under same flow point, when the error polarization, mean that gas meter, flow meter measures than standard scale fast, gas company is profit just, when error is partially negative, mean that gas meter, flow meter measures than standard scale slow, gas company is loss just.
)。
Summary of the invention
For the deficiency existed on prior art, the present invention seeks to be to provide a kind of gas meter, flow meter measuring apparatus of round-off error in real time, there is the real-time correction technique of error, improve Product Precision, realize that a table can meet the metering range of G1.6, G2.5, G4 three table in the past simultaneously, also have in addition long-time with the error correcting technology after gas, after gas meter, flow meter has been used the volume number of regulation or after having used official hour, graph of errors is whole to be revised once, avoids occurring that diaphragm gas meter occurs long-time partially negative by integral body after gas.
To achieve these goals; the present invention realizes by the following technical solutions: a kind of gas meter, flow meter measuring apparatus of round-off error in real time; comprise can, metering movement, sampling sensor, master control circuit plate and CPU4 and protecting sheathing; can inside is provided with the metering movement; can one side is provided with sampling sensor; the sensor arranged outside has master control circuit plate and CPU, and master control circuit plate and CPU arranged outside have protecting sheathing.
