Basic programming setup
the storm's early stage or “first flush.” First flush grab and main program flow-weighted
composite samples are automatically segregated. The first flush sample volume may
be set independently of the sample volume for the flow-weighted composite.
•
The special storm water program allows an external device to initiate the start of the
sampling program. A dry contact closure across Pins B and D on the Auxiliary
receptacle, held closed for at least 61 seconds, is required.
•
When sampling with multiple bottles, the sampler can be programmed to collect one
large “first flush” sample (or small multiple samples) at timed interval(s). The number
of bottles segregated for the first flush sample is selectable. Concurrently,
flow-weighted samples are collected from the beginning of the storm until all
remaining bottle(s) are filled, or after a user selected time has elapsed.
•
Storm water samplers are equipped with a special pre-rinse that occurs only with the
first sample collection. This “one time only” rinse ensures a clean intake for
installations that may remain dormant for extended periods, and extends battery life
by eliminating the pre-rinse for subsequent samples.
