Considerations related to the MDLR determination for the SENSIA OGI’s
- Leak observation is done at distance short enough to ensure the leak resolvancy with various pixels
- Characterization test conditions:
o Background temperature controlled
o Outlet Orifice Diameter= ¼’’
o CH4 diluted with N2 (25% methane)
- Gas Detection condition using High Sensitivity Mode
