REMOTE METERING APPARATUS HAVING TEMPERATURE/PRESSURE CORRECTION FUNCTION OF GAS METER, PARTICULARLY CONCERNED WITH CORRECTING ERROR CAUSED BY CHANGE IN TEMPERATURE AND PRESSURE

摘要

PURPOSE: A remote metering apparatus having a temperature/pressure correction function of a gas meter is provided to detect accurately gas meterage by correcting a error caused by a change in temperature and pressure. CONSTITUTION: A remote metering unit(130,130') converts a measured value of a gas meter to an electrical signal and outputs a digital value corresponding the electrical signal. A temperature sensing unit(120,120') is installed at an inside or an outside or a near side of a gas pipe line in order to sense a temperature of gas and output a digital value corresponding the sensed temperature. A metering correction unit(140,140') is connected to the remote metering unit and the temperature sensing unit in order to correct the digital value by using the sensed temperature and a temperature correction logic. A communication unit(150,150') transmits data including the corrected value to a gas supply system.
