Method for remotely reading metering-value in a gas meter along with temperature/pressure-corrected metering-value through two-wire line, and apparatus and system for the same

摘要

2-wire metering of gas meters with temperature and pressure values, and error correction line weighing of remote automatic meter reading system and method and apparatus is disclosed for this. Coupled to a capacity type gas meter of each suyongga and a plurality of the automatic remote meter-reading apparatus having a temperature and pressure error correction converts the weight data of the predetermined size of the gas meter for the automatic remote meter-reading (1 unit) by the metering pulses and that the metering convert the value Integer calibration weight value adjustment for temperature and pressure errors contained in the value of the calibration metering pulse next, the metering pulses and correcting the weighing transmission combines the pulse on the two lines communication lines for data collection relay unit nearby do. In the data collection relay unit receives the pulse combination signal and separates the metering pulses and metering pulses and correction, from which to extract the weight data and the corrected weight value.
