How does open path gas detector work?
In an open path gas detection system, a source unit emits a high energy beam of a specific wavelength. The target gas will absorb some of the irrigated energy and emit the rest. The detector unit detects the emitted energy at specific spectral bands, according to the target gas.
Where is the best place to put a gas detector?
Install your natural gas detectors in locations close to sources of natural gas. This includes, placing them in any room with windows or a gas appliance such as your kitchen and your basement. When adding to a room with windows, be sure to position natural gas detectors higher than all doors and windows.
How high should a natural gas detector be placed?
For these gases, it is best to install the sensor within inches of the ceiling. Toxic gases: Where safe breathing levels are the main concern, sensors should be located in the typical breathing zone, which is 4 to 6 feet from the floor.
What is LFL meter?
Fixed point flammable gas detectors measure concentrations in percent of the Lower Explosive or Flammable Level (%LFL). Open path devices measure in LFL over distance in meters (LFL. m) e.g. A 5 meter gas cloud with a concentration of 50% LFL will read 2.5 LFL.
Where should natural gas detectors be placed in a home?
Gas detectors should be installed in the room where a gas escape is most likely to occur. Natural gas detectors should be installed above the level of a possible gas escape and near the ceiling (typically < 30 cm (12 inches) from the ceiling), in a place where air movements are not impeded by furniture and furnishings.
Is there a natural gas leak detector?
Propane and Natural Gas Detectors If you need to locate the exact source of a gas leak, it’s best to go with a portable gas detector like the Y201 Portable Propane and Natural Gas Leak Detector. With this device, you can trace gas leaks indoors or outdoors.
What is IR gas detector?
Infrared gas detection is a method for detecting combustible hydrocarbon gas with infrared light. The detector consists of a source of infrared light, an optical filter to select the proper wavelength and an optical infrared receiver.
Does natural gas rise or fall?
Natural gas is always lighter than air, and will rise in a room if allowed to escape from a burner or leaking fitting. On the contrary, propane is heavier than air and will settle in a basement or other low level. Incomplete combustion can occur when the gas mixture is richer than 10%.
Should you have a natural gas detector in your home?
Along with carbon monoxide (CO) detectors, you should also install natural gas detectors in your home. Natural gas is commonly used in homes – to heat household appliances – but it can be extremely dangerous.
