f.Enter the Program Time Limit. NPDES typically requires monitoring during the first three hours of any given storm. If the flow volume was not as high as expected, flow-weighted sampling could continue for some time as flow rates drop off and sample intervals

become longer.

Step 17 - Timed Bottle Sets

Timed Bottle Sets enables a single sampler to function like multiple samplers. Timed Bottle Sets takes a 24-bottle sampler and sample using the first 12 bottles on the first day and the second bottles on the next day.

When a subset of bottles is set aside for each user defined time interval the sampler will treat that subset as if it were the entire set. At the end of the time interval the sampler will switch to the next subset and continue sampling.
