Responder Advanced Mobile LDS

thomson-admin — Wed, 04 Sep 2024 03:01:23 +0000

The Responder Advanced Mobile LDS is an advanced leak detection solution from Aeris Technologies, Inc. that transforms any vehicle into an advanced mobile leak detection system in minutes.

Responder combines breakthrough Aeris MIRA sensor technology, wind and GPS data with advanced analytics to produce the world’s first portable, real-time mobile leak-mapping tool.

Responder systems leverage the highest ethane sensitivity in the industry, enabling the highest discrimination of leaks from confounding bio- or thermogenic interferences, eliminating false alarms.

Key Features:

Unmatched <1ppb/s sensitivity for CH4 and C2H6
Reduced false alarms via superior ethane sensitivity
Real-time analysis, updating of maps to identify leaks
1 or 2Hz operation, 1m GPS accuracy
Installs in minutes, no vehicle mods required
Miniature, magnetically mounted sonic
Logs and prioritizes leaks for ground surveys
Smallest size, lowest weight, power and cost
Advanced analytics to locate leaks, cloud capability
Overlay GIS files for pipeline inspection
Data storage and analytics services available

Responder systems require essentially no vehicle modifications, are 1/10th the size, weight, and power consumption of competing systems, and only require minutes to install.

The systems provide seamless updating of maps in real-time, and can be moved from one vehicle to another with no tools or special skills required. In Responder systems, the miniature Aeris sensor can be uniquely un-docked from the vehicle and used as a handheld leak search tool for ground surveys, which is not possible with competing systems.

Real-time Responder user interface can be either displayed in a real-time mode or post-process mode, wherein the leak data are hidden from the driver but the route is still shown. When leaks are encountered, a marker is dropped and location logged into a list, which prioritises leaks based on various metrics.

Model N901 THC/CH4/NMHC

thomson-admin — Fri, 11 Dec 2020 04:41:16 +0000

The Model N901 is a near-continuous hydrocarbon gas analyzer that measures the concentration of Methane (CH₄) and Total Hydrocarbons (THC) in air. The concentration of the non-Methane (NMHC) component is calculated by the subtraction of CH₄ from THC, with high sensitivity and accuracy. The hydrocarbons are measured using a Flame Ionization Detector (FID), in combination with gas chromatography (GC). The instruments range and performance are tuned specifically for use in ambient air quality monitoring assessments.

The Model N901 is designed for simple operation and maintenance with a modular hardware and electronics architecture. A long-life stainless-steel fritted filter is used at the sample intake to effectively remove particulate matter without introducing any gas-phase measurement artifacts. Instrument operation, calibration functions, chromatogram views, and data handling are all automated and controlled using the internal NumaView Software (NVS) interface, without the need for an external PC.

For remote connection to the N901 instrument, Teledyne API’s NumaView Remote PC-based Software provides a virtual interface, instrument controls, and data downloading capability to all TAPI analyzers operating NumaView Software.
