Sierra Instruments, Inc.

Choose high accuracy gas flowmeter for increased precision and profitability - Monitoring and Testing

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.

Each gas mass flowmeter is designed so the physics are correct. Each precision gas flow meter provides excellent performance with its patented, inherently linear Laminar Flow Element (LFE) design, advanced platinum sensor technology, and Sierra’s proprietary frictionless-hovering control valve. Every digital gas flowmeter gives end users ultimate flexibility with an innovative and user friendly Pilot Module, a front-mounted or hand-held control device that allows users to Dial-A-Gas, change flow rate, modify engineering units or reconfigure their gas flowmeter.

Our digital communications solutions offer engineers and systems integrators full system integration and networking capability for their precision gas flowmeter, with Sierra's mass flow control systems. Multiple Sierra gas flowmeters and controllers can be networked together into sophisticated systems to make almost any gas mixture or blend, whether, argon, air, carbon dioxide, natural gas or wet gas . Digital communications solutions include: Modbus RTU and Profibus DP. For enhanced networking capability, including two digital relays, totalization, inputs, and display, add the Compod Control Module to easily program your flowmeter for a wide variety of common gases, including natural gas and wet gas, and process controls applications.
