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.
Sierra designs and manufactures a wide range of today’s most advanced analog and digital gas flowmeters and controllers, including a high-pressure gas flowmeter. For gas mixing and blending applications, accuracy and precision control and measurement are always a central requirement. Sierra’s precise flow meters and controls provide end-users with high performance in gas mixing and blending applications like creating artificial atmospheres, gas mixing in manufacturing, inerting and gas chromatography.
The measurement of gas flow in large ducts or pipes offers its own set of challenges. Large ducts and pipes often have swirls or turbulence in them which makes measurement of true gas flow difficult. Sierra has developed a number of solutions to this vexing problem, including stand-alone flow conditioning elements and multiple arrays of thermal sensors. By including hot taps and purging systems, such arrays can be very flexible.
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.
From bulk gas delivery to cleaning to purging operations, Sierra`s mass flow meters and controllers offer the simplicity and robustness demanded in these applications. Our ability to handle corrosive gases, high flow rates and multiple gases with the same unit makes Sierra`s mass flow meters and controllers a tool-makers choice.
The Hilliard Corporation has a complete line of Drive Train products for All terrain vehicles (ATV), and utility vehicles (UTV). Drive Train products solve some of the most common problems related to traction, on-demand 4WD engagement, and turf damage.
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.
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.
