DIGITAL DIAPHRAGM GAS METER FOR COMPENSATING TEMPERATURE AND PRESSURE FOR PRECISELY MEASURING AMOUNT OF CONSUMED GAS BY COMPENSATING FOR GAS FLOW

摘要

PURPOSE: A digital diaphragm gas meter for compensating the temperature and pressure is provided to precisely measure an amount of consumed gas by compensating for a gas flow, which varies according to the temperature and pressure of the gas inputted into the digital diaphragm gas meter. CONSTITUTION: A digital diaphragm gas meter for compensating the temperature and pressure includes a temperature sensor(26) installed at an inlet of a gas flowing pipe(22) in order to measure a gas temperature. A pressure sensor(28) is installed at an inlet of the gas flowing pipe(22) in order to measure a gas pressure. A lead switch(34) is operated by a magnet installed at a rotating plate in order to measure a gas flow passing through the gas meter. A controller(30) is provided to detect a signal inputted thereto from the temperature sensor(26) and the pressure sensor(28).
