Title:
水蒸気の影響に関する天然ガス流量計算の補正
Document Type and Number:
Japanese Patent JP6547059
Kind Code:
B2
Abstract:
A system for measuring concentration of water vapor in a gas includes a pressure sensor configured to sense a static pressure of the gas and a differential pressure sensor configured to sense a differential pressure. A temperature sensor senses a temperature of the gas. Circuitry estimates determines a concentration of water vapor in the gas based upon the measured pressures and temperature.
