Sierra Instruments, Inc. applications

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.

We manufacture a variety of mass flow technologies for precision measurement of gases, liquids, and steam.

From heavy industrial to research and analytical applications, Sierra has a wide range of digital air flow meters and controllers with digital output protocols for easy network integration. Sierra offers air flow meters and across two core technologies: Immersible Thermal and Capillary Thermal.

Oil wells almost always produce natural gas (“associated gas”) along with the petroleum. In many cases, it is uneconomical to process due to heavy contamination. As a consequence, this gas is combusted, “flared” or simply vented as-is during upset conditions in the process. Newly updated EPA regulations like 40 CFR Part 60 Subpart OOOO (also known as Quad O) as well as the new RSR MACT rule for refineries, requires oil & gas companies to report the flare gas emitted to our atmosphere. Monitoring the fuel at the inlet of the flare is part of meeting these EPA requirements. Our QuadraTherm thermal mass flow meters with qMix gas mixing software are ideal for flare and combustion gas measurement.

Accurate liquid flow sensor measurement can reduce water bills, determine leakage rates, and increase system efficiency. Solve accurate water and industrial liquid flow measurement requirements with clamp-on or insertion ultrasonic flow liquid flow meters featuring precision sensing elements or our complete line of multivariable mass vortex meters.

As an innovative steam flow meter manufacturer, Sierra’s InnovaMass brand was the first multivariable mass vortex flow meter to launch to market in the late 1990s. Today our flow meter steam technology is successfully used across numerous applications. Sierra`s multivariable product line features an in-line version, the InnovaMass 240 vortex flow meter; a unique immersible version, the InnovaMass 241; and the InnovaMass cryogenic version.

Sierra has a complete line of fuel flow measurement instrumentation.  Our ultrasonic and vortex flow meters are an ideal choice for accurate filling, transport and usage fuel flow applications found in general industry. Through our Automotive Test Division, we also manufacture a line of ultra-high accuracy vehicle consumption measurement system called FuelTrak.

Thermal mass flowmeters and controllers are ideal for Argon application where precision is key. Sierra specializes in accurate mass flow measurement and/or control of Argon gas. Popular applications range from general industrial process control, inerting and steel purification processes to name a few.
