t is a fact of the industry that oil and gas companies
are required, by various rules and regulations, to
routinely perform gas sampling to establish gas
composition, flow rates and gas properties. In order
to comply with regulations, gas sampling tools must
achieve high accuracy at low flows with varying gas
compositions, temperatures and pressures. For many
technologies, these requirements can be difficult to
meet.
This article reviews various gas sampling challenges
and describes how several recent innovations in thermal
mass flow sensor technology offer gas analyser
manufacturers, and oil and gas companies, new flow
metering options to solve the gas sampling challenges
that vex the industry.
