QuadraTherm® 640i Air Mass Flow Meter

Overview

Industry's Most Accurate Gas Thermal Insertion Mass Flow Meters

The QuadraTherm® 640i is the most accurate insertion-probe thermal mass flow meter for gas mass flow rate measurement on the market today, achieving gas mass flow rate accuracy never before possible, +/- 0.75% of reading above 50% of full scale. The QuadraTherm 640i gas mass flow meter marks an accuracy breakthrough in thermal dispersion technology achieving extreme precision with "percent of reading" accuracy, which for the first time rivals accuracies of Coriolis technology for measuring gas mass flow rate.

Flare Gas & Combuster Gas Measurement

Flare Gas & Combuster Gas Measurement

It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of "flaring" this excess gas into our atmosphere has resulted in government regulations like 40 CFR Part 60 Subpart OOOO (also known as Quad O) as well as new RSR MACT rule for refineries requiring oil & gas companies to report the flare gas emitted. Traditionally, in upstream oil and gas applications orifice plates and turbine meters have been used to measure the flare gas to comply with these government regulations.

As the drive towards energy independence in the United States continues at full speed, oil and gas companies are turning to hydraulic fracturing to increase production. Increasingly stringent state and national regulations for flare gas in particular now require the installation of mass flow measurement instruments to measure waste and excess gases burned off as a result of the hydraulic fracturing process. For gas wells alone, the EPA estimates that the cost of compliance will rise to$754 million per year by 2015.1
