Thermal Air Flow Meters for Light-Industrial Applications
Specializing In Thermal Air Flowmeters
Our light-industrial thermal air flow meters are a cost-effective solution for measuring inert and natural gases or propane.
Boiler Trak™ is an insertion mass flow meter that is optimized for flammable gases, including methane, natural gas and propane and is designed to meet new regulations for monitoring NOx emissions in small to medium size boilers.
Our Fast-Flo™ Model 620S is an insertion mass flowmeter specifically optimized for inert gases with a fast response at 200 milliseconds. It also features a low pressure drop and low-flow cut off.
Featuring a multitude of configurations and body sizes from 1/4" to 1.5", our Model 730 is a high-performance inline mass flowmeters. It has a flow range of up to 20,000 sfpm (standard feet per minute) and can measure most inert gases as well as natural gas and propane.
Our light-industrial thermal air flow instruments are specifically designed to provide a cost-effective solution for all inert industrial gases, for methane (natural gas), or for propane. Our thermal air flow meters provide common-sense solutions for most common air, nitrogen, and methane applications. Because of the small footprint, our light-industrial instruments – Boiler-Trak™, Fast-Flo™ Model 620S, and Fast-Trak™ Model 730 – are a popular choice for Original Equipment Manufacturers (OEM's) who need an economical solution and have space constraints. Sierra's light-industrial thermal air flow products deliver an exceptional turndown ratio and high accuracy at a price that can't be beat. Sierra also manufacturers a complete family of Heavy-Industrial Thermal Mass Flow Meters.
Sierra has certified several meters ideal for Greenhouse Gas (GHG) measurement meeting all requirements defined by the EPA (40 CFR Part 98). Our GHG Certified mass flow meters provide an economical way to totalize methane or natural gas burned, enabling the calculation of CO2 equivalent emissions. Sierra has extensive experience in producing highly accurate and repeatable mass flow meters for methane (CH4) as well as N20, SF6, HFC’s, PFC’s and CO2 as called out in the EPA mandate.
