Daily Instrument Check Smiley 9/14/2010
Are there any sources for a daily check setup for the flow rates as described in 40 CFR 60.18? I need a meter that reads down in the range of the MDLR and a metering valve that would provide a flow that low. My calculations tell me I need a flow of 3 grams per hour to document my camera for AWP use.

Have you found a daily check? I am looking for a flow meter, but have not found one as of yet. We were looking at using a compressed gas like propane as a surrogate and use a flow meter to verfy a detection level at site conditions (distance, wind, background, etc.).
