CALORIMETRIC METHOD FOR MEASURING FUEL GAS FLOWRATE Russian patent published in 2005 - IPC

Abstract RU 2256156 C2

FIELD: flow metering.

SUBSTANCE: proposed method depends on use of fuel gas flowrate as a function of thermal power produced. Use is made of thermal power released during combustion of gas under test in gas burner supplied thereto at constant speed. Power value is determined as difference between initial power of regulating heater and power of same heater when burner is operating. Flowrate of fuel gas under test is determined as quotient obtained when thermal power released in combustion of investigated fuel gas supplied at constant speed is divided into its volumetric calorific value.

EFFECT: enhanced measurement accuracy.
