Flare Gas Measurement Innovation: Retain Flow Metering Accuracy Even if Gas Composition Changes


Dec 12, 2016
Matthew Olin, President & CEO
Written By:
Matthew Olin, President & CEO

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 […]

Reducing Costs of Steam Flow Measurement


Aug 19, 2016
Matthew Olin, President & CEO
Written By:

Traditionally, steam flow has been measured with a differential pressure device. This is typically an orifice plate. However, such devices are inherently volumetric flow measurements. As we have discussed in previous blog posts, changes in pressure and temperature will change the mass flow rate of steam. Even a “small” change of 10% in steam pressure […]
