Among the challenges in gas flow measurement using a thermal mass flow meter is the change in gas composition.
Gas Composition Changes
Gas composition changes are not as much of a problem when measuring natural gas, biogas or landfill gas, as the effect is likely to be negligible. However, gas composition variation at a refinery and chemical plant applications can significantly affect flare gas flow measurement resulting in erratic performance.
If gas composition change develops with the use of your Sage flow meter, know that because of Sage Metering’s experience and our proprietary algorithm, Sage can provide new calibration factors for the meter. Simply provide Sage with the serial number, the new gas composition, and the operating conditions (flow rate, temperature, pressure, pipe size). Our Engineering Department will calculate new factors to load into the meter using INSIGHT software or another Modbus communication device. Call us today to discuss at (866) 677-7243.
Flare Gas Flow Measurement
We use flare gas and vent gas systems around the world in industries including oil and gas production, refining, chemical processing, gas plants, wastewater treatment facilities and landfills. The systems burn off waste gases, dispose of surplus gases and protect people, equipment, and the environment. The measurement and monitoring of flare gas assure that the flare system is operating correctly. Unfortunately, there are inherent challenges when measuring flare gas such as working in hazardous locations, extreme flow variation, and changing gas composition.
