FLOWMETER, METHOD FOR MEASURING FLOW RATE USING FLOWMETER, FLOWMETER CORRECTING DEVICE, AND METHOD FOR CORRECTING FLOWMETER BY SAID DEVICE

摘要

The present invention relates to a flowmeter for measuring the flow rate of gas flowing through a pipe, comprising: a measurement probe of which a lower portion in the longitudinal direction is inserted into the pipe; a speed measurement part for measuring the speed of flare gas, while being connected to the measurement probe; a density measurement part for measuring the density of the flare gas, while being connected to the measurement probe; and a data analysis part for calculating the flow rate of the flare gas on the basis of values measured by the speed measurement part and the density measurement part, and storing and analyzing the calculated flow rate.
