Sierra Instruments, Inc - Heavy-Industrial Graph

	Contact Us


	Our Industrial Thermal products utilize “Immersible Thermal” sensing technology and are widely used for precise mass flow measurement in light-industry, heavy-industry, hazardous environments, and Ultra High Purity (UHP) applications. Rugged and reliable, our line of industrial thermal mass flow meters are work horses in industry and are commonly used to measure Air and Natural Gas as well as all other industrial gases and mixtures. Full scale flow rates are above 1000 slpm (35 scfm). We offer a high temperature (HT) industrial thermal version as well for high temperature gas above 300C (700F). For high pressure gas (above 250 psi up to 5000psi), we recommend our Multiparameter Vortex products as a great solution. We are glad to help you select the right product for your application. Request a quote and a local expert will contact you to discuss your application. You may also contact us or use our live help function to get in touch with one of our friendly applications engineers.

Model 780S Flat-Trak™ Inline Mass Flow Meter with Flow Conditioning
Like its cousin the Model 640S, the Flat-Trak Model 780S provides repeatable, rugged, and reliable performance. Additionally, the product features Sierra’s flow conditioning elements. Product accuracy is ± 1% of reading +0.5% full scale, and the flow range is up to 20,000 sfpm (air) with standard accuracy.

Model 620S Fast-Flo™ NEMA 4X (IP65) Insertion Mass Flow Meter
A 200 msec fast time-response microprocessor-based transmitter in a NEMA 4X (IP65) enclosure. Product accuracy is ± 1% of full scale and the flow range is up to 20,000 sfpm (air) with standard accuracy. Boiler-Trak™ is designed to provide an economical and easy to install solution for natural gas, propane or butane measurement to heaters and boilers. Product accuracy is ± 1% of full scale and the flow range is 80 to 1600 SCFM (natural gas) with standard accuracy.

Model 640S Steel-Mass™ Insertion Mass Flow Meter
Accurate and repeatable, this product is a rugged and reliable mass flow measurement workhorse in heavy industrial applications. Product accuracy is ± 1% of reading +0.5% full scale, and the flow range is up to 20,000 sfpm (air) with standard accuracy. It inserts easily into ducts and pipes to monitor total gas mass flow rate.
