NARRATOR V/O:
The portable, reliable Remote Methane Leak Detector or RMLD is changing the way leak surveys are conducted by offering a quicker, safer way to detect natural gas leaks.
Now instead of having to walk the entire length of the service line to check for methane leaks…
The Remote Methane Leak Detector can quickly and efficiently detect leaks up to one hundred feet away.
Because it utilizes a new laser technology, the remote detector enables surveys of hard-to-reach areas and difficult terrains.
For utilities, this new time saving method represents a significant improvement in productivity and safety.
Available gas detectors that deploy technologies such as flame ionization must be positioned within the leak plume to detect the presence of methane.
The new Remote Methane Leak Detector does not have to be within the gas plume because it uses laser technology known as Tunable Diode Laser Absorption Spectroscopy. As the laser passes through a gas plume, the methane absorbs a portion of the light, which the RMLD then detects.
This technology makes it possible to detect leaks along the sight line with out always having to walk the full length of the service line.
The RMLD is safer to use because it is operated outside the leak area. Now you do not have to be within the plume area to detect a leak.
Using laser technology, remote detection allows you to safely survey areas that may be difficult to reach such as busy roadways, yards with large dogs, fences and other hard to access places.
Simply aim the laser along the gas line or area to be checked.
The RMLD easily detects the leak.
The Remote Methane Leak Detector consists of two interactive components…
A laser emitter/receiver subsystem…
A signal processing / User Interface controller…
These buttons provide basic operation of the RMLD. First, depress the On/Off button located on the bottom of the unit to turn the unit on or off . . . . press the Select button to scroll through the menu items such as volume adjust, spotter on or off, alarm level adjust and background light. The Up or Down arrow keys are used to increase or decrease values…turn a function on or off . . . .or to acknowledge a user prompt. To scroll through the detection mode selection . . . .
press the DMD button.
1) On the bottom of the unit you will find connections for the battery charger, ear phone, RS-232 serial port and external battery.
Each day you should perform a self test on the unit. First turn on the unit and allow it to warm up for about 3 minutes. Next, …( place the black shield in front of the calibration cell at the end of the case )…. select self test from the menu…. press the up arrow key to initiate the test . . . . wait for the “OK” to appear . .(remove the shield). . . press the up arrow to continue and wait for the test to complete. A successful test will be indicated by the “Self test OK” on the display. Press the up arrow key to acknowledge. Return to the main display by the Select button.
Should a test fail, the display will show “Retry”. In this case, repeat the above process.
The invisible IR laser beam is transmitted from the launch port. With a normal background, such as brick, concrete, and grass, it has a maximum distance of up to 100 feet away. The laser light beam width is about 22 inches at 100 ft. It is important to note that the laser beam width increases as the distance increases. This is why it is much easier to detect leaks from a distance of 10 to 15 feet and beyond.
To detect leaks, some of the laser light is reflected by the target back to the detector. This reflected light is collected and converted to an electrical signal that carries the information needed to deduce the methane concentration.
The laser light is selective to methane only, and will not false alarm on other hydrocarbons or water.
This signal is processed so that methane concentrations can be reported in parts per million per meter or PPM-M.
PPM-M is the sum of the methane concentration times the distance the light travels…. while PPM measures local concentration.
The RMLD uses a system of tones to indicate detections, concentration level, or fault conditions.
While using the pure tone detection mode, a continuous tone is played relative to the instantaneous concentration level. The higher the pitch of the tone, the higher the concentration level. No sound at all will indicate a low light level condition or instrument fault. Note that the pitch level increases as you scan at a further distance. This is due to the ambient amount of methane in the air.
While using the Digital Methane Detector (DMD), no sound will be heard until a detection of methane occurs. The pitch of the sound will be relative to the methane concentration. The higher the pitch, the stronger the methane concentration is.
A low-continuous sound will indicate the light level is to low for the DMD, A low-pulsating sound will indicate a very low light level condition or instrument fault. The operator needs to move in closer to get in range.
The DMD will indicate detection when the PPM-M exceeds the average background level, or when the average PPM-M exceeds 80. While the low light warning is sounding, the RMLD may still be able to detect very large gas concentrations, indicated by a high pitch tone.
In order for the RMLD to detect gas, three conditions must be present . . . a gas plume of sufficient size and concentration, a sufficient reflective background and the laser must pass through the gas plume.
There are several factors that influence the gas plume size and concentration. First, very low flowing leaks may produce small to non measurable plumes. Also, surface types such as concrete, will spread the leak and create spot leaks through surface cracks and holes. Weather conditions like high winds and higher temperatures will cause the plume to dissipate faster.
The first thing you will need to learn when surveying with the RMLD is to control the aiming of the laser and rate of sweeping. Radical or abrupt motion may cause the RMLD to give false detections due to rapidly changing distance or background that the laser detects. Learn to use a smooth sweeping motion and steady rate of distance change.
Here the technician is seen walking along the main. Note the speed at which the technician walks and the rate in which he is sweeping the laser. Care must be taken to scan typical areas where leaks will vent, like cracks, edges, patch-work and meters. Work the laser to scan about 15 to 20 feet out in front of you. Use the spotter laser to effectively know where you are scanning.
The green, visible spotter laser is under the control of the operator. Avoid staring directly into it and be courteous to others by not shining it into their eyes. Also, be careful to not distract car drivers.
In this example, the technician is demonstrating proper Service Line scanning with a visible meter or inside meter vent. Note how he carefully scans the area of the service tap, up the service line, pausing on any visible vegetation damage, pausing around the riser and then scans in a horizontal pattern around the meter. When at longer distance, just a couple of sweeps is needed due to the beam size. It works best to scan the meter from a distance of 15 or more feet away.
Here we see the technician scanning for a leak when he doesn’t know the exact location of the meter or service line. He starts by searching the road edge, probable tap locations, then performs an X-pattern to survey along the house foundation and yard. Adaptation of this basic pattern may be needed to account for local installations or specific company procedure.
In the event a leak is detected, the technician then needs to verify it. Larger leaks are easily verified by sweeping the laser in and out of the plume. While using the DMD, the higher the pitch the larger the leak concentration.
In the event of a very low flowing or venting leak, verification takes a bit more investigation.
Keeping a distance of about 10 feet from the leak, sweep the laser back and forth across the location. Use the pure tone for very small leaks. Keep in mind that the RMLD detects all the gas in the path of the laser, If there is not a strong verification, search around the area to be sure you didn’t walk past it.
The RMLD can be easily used to determine if the leak is located on the meter or is underground. Keeping a distance of about 5 to 10 feet and trying to position yourself up wind, start at the ground and work the laser up and around the meter. Listen for the highest pitch to locate the hot spot on the meter. At this distance the laser spot is very small and precise.
In adverse weather conditions such as gusty winds, rain, wet ground, or other conditions that reduce the ability of a leak to vent, you must slow down the scanning rate and take longer at possible leak locations to catch highly variable plumes.
Valid PPM-M readings can be obtained from targets up to 100 feet away. Actual distance may vary due to target surface and condition. When the low light tone is heard, you need to move in closer.
For best results when scanning at distances greater than about 50 feet, it is important to slow down the scanning rate and take care in pointing the laser.
When taking aim, use the spotter laser or the sighting marks on the side of the transceiver to ensure proper scanning of the target area.
Be aware of the elevation of the ground. Scanning across the top of a knoll or past the edge of a structure can result in beam skips or a sudden change in distance . . . . giving you a false detection.
Obstructions or variations in the landscape can cause “Dark zones” where the laser doesn’t scan. Look for the best angle to thoroughly scan these areas. Scanning up a hillside may cause beam skipping or dark zones around the foundation of a structure.
Sometimes while scanning at longer range, a false detection will occur due to a rapid change in distance the laser beam actually covers. If this occurs, pause at this distance and sweep across the area to determine if gas is present.
Additional false detections may be caused by certain surface conditions, including glass, reflectors and polished surfaces. If this occurs . . .alter your angle and re-scan the area.
Some surface conditions reduce distance…such as asphalt and wet surfaces -- especially wet asphalt. In these circumstances, you may need to move in closer to the target.
The Remote Methane Leak Detector has been proven to be effective in a variety of utility field tests.
In the independent validation tests, the RMLD has proven to be a highly effective leak survey instrument, compared to flame ionization and similar equipment, but with the added advantage of remote detection.
The Remote Methane Leak Detector is changing the way methane surveys are conducted…providing a new, safer, more efficient tool for detecting methane leaks.
