Document Type and Number:
WIPO Patent Application WO/2022/105081
Kind Code:
A1
Abstract:
A gas energy metering flowmeter, comprising: a volumetric flow measurement unit used for measuring a volumetric flow Qn of natural gas; a calorific value measurement unit comprising an optical sensing module, an acoustic velocity sensing module, and a calculation module, and used for measuring a unit calorific value H of the natural gas; and a calculation unit used for calculating energy E of the natural gas, E=Qn×H. Rapid and accurate metering of the energy E of the natural gas can be achieved.
