SEMTECH HI-FLOW 2

a replacement for the obsolete Bacharach HI FLOW

SEMTECH HI-FLOW II

For over 50 years, Sensors, Inc. has built a reputation for gas and particulate measurement products under the SEMTECH brand in the automotive industry. Our fugitive methane analyzer is the latest entry in Sensors Emissions Measurement Technology (SEMTECH) family. Sensors’ fugitive methane analyzer brings to bear our emission measurement experience into the oil and gas industry with a focus on leak detection and repair (LDAR).

Sensors, Inc. is proud to present the latest in direct quantification of leaks in the 0.0005 to 25 CFM (0.015 to 700 lpm) range with accuracy better than 5%. This device uses state-of-the-art flow and gas sensing technologies that are integrated into a handheld unit for accurate measurement during established LDAR programs.

The SEMTECH HI-FLOW 2 is a robust, portable, battery powered, high volume sampler for the accurate quantification of fugitive methane emissions, comprising:

  • Sampler - Handheld device with a high-volume vacuum sampling fan and total flowrate monitor
  • Analyzer - Portable control module (which can be carried, placed on the floor, or mounted to a backpack) housing the gas sensor technologies, control electronics, and battery pack

The combination of these two components (with a variety of sampling adapters) allows the entire fugitive methane emission to be captured, diluted, and quantified accurately.

By utilizing Tunable Diode Laser Absorption Spectroscopy (TDLAS) combined with an innovative sampling system, accurate concentration measurements of fugitive methane over 4 to 5 orders of magnitude can be performed without any cross-interference from other gases present in the captured leak. Coupled with an accurate measurement of the extracted flow (methane leak and ambient air) the volume- and mass-based leak rate of the fugitive methane can be determined with high accuracy over a wide range (for example 0.0005 to 25 CFM (0.015 to 700 lpm)).
