It was not so long ago that gas detection was biological, and canaries were the state-of-the art gas detectors. Until well into the 20th century the little birds were used to detect build-ups of deadly carbon monoxide in mines and thus saved the lives of thousands of miners. The canaries were retired when electro-chemical sensors […]

Palladium-Nickel-Based Hydrogen Sensor
Being able to accurately measure the presence of gases is crucial to the success of any process. The latest monitoring technologies are particularly focused on hydrogen, oxygen, carbon monoxide and hydrogen cyanide.The presence of other gases is an important requirement in many process industries for both process optimisation and for safety. These measurements are difficult […]
Corrosive Fluids No Match for This Sensor
Generally, the wall thickness of Coriolis measuring tubes are significantly less than the associated process piping, which will tolerate a higher rate of corrosion before failing. This is an area where wetted material selection for a Coriolis meter is critical. Tantalum has been used by some Coriolis manufacturers in the past, but the twin bent […]
Oxygen Analyzers for Gas Pipelines
Oxygen analyzers for natural gas pipelines received a new friend today as SpectraSensors, Inc., announced the model OXY4400. A common problem associated with the production of natural gas is the presence of oxygen which can enter via air leaks in upstream equipment. The negative impacts of oxygen in natural gas include corrosion of piping, reduced […]
