RMLD

Revolutionary Technology
The new, portable, reliable Remote Methane Leak Detector (RMLD.) is changing the way methane surveys are conducted.
Instead of having to walk the entire length of the service line to check for methane leaks.the RMLD
can quickly and efficiently detect leaks up to one hundred feet away allowing remote detection of hard-to-reach areas and difficult terrains.

Remote detection allows the user to safely survey areas that may be difficult to reach, such as busy roadways, yards with large dogs, locked gates, pipes suspended under a bridge, indoor commercial piping and other hard to access places.

For utilities and their employees, this new timesaving method represents the potential for significant productivity gains, reduced operations and maintenance
costs, and a safer survey.

Tunable Diode Laser Absorption Spectroscopy
Available gas detectors that deploy technologies such as flame ionization must be positioned within the leak plume to detect the presence of methane. The RMLD does not have to be within the gas plume because it uses laser technology known as Tunable Diode Laser Absorption Spectroscopy. When the laser passes through a gas plume, the methane absorbs a portion of the light, which the RMLD then detects.
This quantum leap in technology makes it possible to detect methane leaks along the sight line without always having to walk the full length of the service line.

Components
The Remote Methane Leak Detector consists of two interactive components; a transceiver subsystem and a signal processing/user interface controller. The transceiver has two lasers; an infrared laser beam that is non-visible and is continuously on while the unit is turned on. The green spotter laser is similar to those used for presentation pointers and is turned on by the operator by depressing the trigger button.

How Does It Work?
When the infrared laser beam is transmitted from the launch port some of the laser light is reflected by a normal background such as brick, concrete, grass, etc., to the detector. This reflected light is collected and converted to an electrical signal that carries the information needed to deduce the relative methane concentration. This signal is processed so that methane concentrations can be reported in parts per million meter or ppm-m. The laser has a maximum distance of up to 100 feet and is selective to
methane only. It will not false
alarm on other hydrocarbons.
