Sierra Instruments, Inc.

Thermal flowmeter solutions for energy applications - Energy

Sierra thermal flowmeters provide precise flow measurement solutions for a variety of industrial and energy-related applications such as flare gas measurement, cogeneration, biogas measurement, district energy applications, clean coal technology and many more.

Acknowledged as North America's bestselling thermal flowmeter and sensor (2009 Flow Research), our heavy-industrial thermal mass flow meters are designed for the most demanding industrial mass flow measurement applications. We manufacture a wide variety of inline and insertion thermal sensor flowmeters for precision measurement of gas mass flow rate in industrial applications.

Our thermal flowmeters range from our highest performance QuadraTherm four-sensor design, to our more traditional, and also very accurate, two-sensor instruments. Now with qMix gas mixing software our QuadraTherm can field-adjust for gas compositional changes right through the on board software.

For customers who enjoy the many benefits of thermal technology—wide turndown ratio, very low pressure drop, no moving parts, application flexibility, and a direct gas mass flow rate measurement— you get extreme precision with percent-of-reading accuracy as part of the total QuadraTherm package. Each thermal mass flowmeter features the long-term stability of our patented no-drift DrySense velocity sensor technology backed by a lifetime warranty.

For easy systems integration, we offer the following digital communications solutions: HART, Modbus RTU, and Profibus DP. View all of our digital communications solutions offering turnkey solutions for industrial systems automation and control.
