Sierra is an expert in the control of high flows of gases. With our large and powerful control valves and PID valve control, Sierra`s mass flow controllers, with industry-best low pressure drop, can control much higher flows than equivalent flow controllers with minimal pressure drop requirements.
Most chemical reactions are based on direct mass flow readings, and thus, Sierra`s immersible thermal mass flow meters and our volumetric vortex and multivariable mass vortex flow meters see extensive used in oil, gas and steam measurement. In addition, process liquid flows can be addressed with our non-intrusive clamp-on ultrasonic flow meters. Finally, our capillary thermal mass flow meters and controllers are perfect for semiconductor processing applications.
Low flow measurement and control is a difficult application. Ultra low flow mass flow controllers can accurately control flows from 0.1 to 0.4 sccm which is ideal for measuring and controlling doping gases for pilot plants and other research houses.
Compressed air isn`t free, so more and more companies carefully monitor and control its usage. We manufacture a range of thermal mass flow meters and vortex flow meters that are ideal for accurate compressed air monitoring.

Precise measurement of natural gas requires high accuracy, low pressure drop and direct mass flow reading—all the hallmarks of Sierra’s immersible thermal, mass vortex and thermal mass flow controllers. Our mass flow controllers are ideal for natural gas flow measurement with 100:1 turndown and no moving parts, providing a robust MFC solution. Our natural gas flow measurement instruments can also handle liquefied natural gas (LNG) via our cryogenic mass vortex meters.
A variety of MS techniques – such as Quadrupole MS, Time-of-Flight (TOF) MS, Ion Mobility Spectroscopy (IMS), etc. have been developed in the past decades, providing new tools for materials analyses. Flow control for mass spectrometry (MS) requires high repeatability and small temperature- and pressure dependency. This is important to achieve a high resolution and instrument resolution. Depending on the size and electrical interface requirements, the Axetris MFC modules or MFC standalone types are the ideal...
