Matthew Olin, President & CEO
Written By:
Matthew Olin, President & CEO

Patented QuadraTherm’s Four-Sensor Design A major thermal sensor breakthrough for Sierra occurred with QuadraTherm, as two new temperature sensors (T2 and T4—see figure below) were added to the existing two-sensor design (T3 temperature & T1 DrySense velocity) used in previous flowmeter models. The two additional sensors perform real-time correction for the heat lost to the outside environment due […]

Written By:
Matthew Olin, President & CEO

Innovative QuadraTherm Four-Sensor Design Traditional thermal sensors have two sensors—one temperature sensor and one velocity sensor, each in a separate probe sheath. QuadraTherm (the term “Quad” meaning “four”) introduces four sensors—three precision platinum temperature sensors and one patented DrySense mass velocity sensor. Performance improvements never before possible are gained as the QuadraTherm Technology isolates forced […]

This month I’ve been blogging about field researcher David Mucciarone, a Stanford University science and engineering associate. He’s part of a team that’s changing the way research about global warming is done, moving from discrete sampling to continuous, real-time monitoring. A key component of that shift is the flow meter in his chromatography-based flow-through sampling […]

Back in December, I shared how the Sierra Smart-Trak flowmeter traveled to Antarctica in 2006 with Stanford University researcher David Mucciarone. As a critical component of his data collection efforts, the flow meter helped him measure the breakdown of inorganic carbon during the Antarctic summer bloom. This important R&D work directly correlated with studies on global […]
