The Sensors, Inc. SEMTECH HI-FLOW 2 is a high-volume fugitive methane analyzer, compliant with OOOOb and ACR methodologies. Touted as a replacement for the obsolete Bacharach Hi FLOW, The Hi-FLOW 2 is a part of the Sensors Emissions Measurement Technology (SEMTECH) family of products. Use the Hi-FLOW 2 to sample for methane leaks on oil and gas sites, designed for leak detection and repair (LDAR ) processes. Rent the SEMTECH HI-FLOW 2 today from CleanAir Engineering.

Direct, accurate quantification of leaks in the 0.0005 to 25 CFM (0.015 to 700 lpm) range with accuracy better than 5%. State-of-the-art flow and gas sensing technologies integrated into a backpack-style with probe unit. Robust, portable and battery-powered, with built-in dilution system; consisting of (1) a handled sampler unit with vacuum sampling fan and total flowrate monitor and (2) control module with backpack bag and body harness.

HI-FLOW 2 utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) and a high-output fan which together facilitates a 3-5x lower detection limit (0.0005 CFM) and a 3x increase in maximum leak rate (25 CFM) when compared to older Bacharach devices. SEMTECH’s TDLAS, tuned specifically to methane (unlike non-dispersive spectroscopy techniques), eliminates the known problems of interferences from other gases present.
