Background: Cummins Inc. uses Scott gas products for calibration of Semtech D mobile emissions analyzers produced by Sensors, Inc. Currently we use the following Scott gases:
1. Quad blend - CO, CO2, NO, CH4
2. Zero air
4. FID fuel - H,He mixture
Sensors, Inc. has a waiver from USDOT attached to the Semtech D for transporting a Scotty size bottle, with regulator attached, inside of the Semtech D analyzer.
1. Can the Semtech D with an enclosed Scotty sized bottle of FID fuel and attached regulator be installed inside of a vehicle cab?
2. Is it possible/legal to use a larger FID fuel bottle (CL size)if it is remote mounted from the Semtech and installed in an approved enclosure.
3. If answer to #2 is yes, please provide details on legal requirements.
Please cite applicable regulations.
