6700 SAMPLERS
Example 6 Storm Water Runoff Sampling
Storm water runoff sampling is an ideal application for two-part
programming. Typical monitoring permits require that a series
of timed samples be taken during the initial portion of the storm
event, followed by flow paced samples during the remainder of
the event.
Note
To enable the Bubbler Module
programming screens, insert the
module before turning on the
sampler.
This example assumes that a Rain Gauge and a Bubbler Flow
Module are connected to the sampler. Using a 24-bottle kit, it
divides the bottles into two groups, with six bottles assigned to
part ‘A’ and 18 to part ‘B.’ The sampler will begin taking samples
after being enabled according to programmable enable controls;
that is, when the rain gauge detects 0.15 inches of rainfall in 30
minutes, and the module detects a flow stream level of more than
0.25 feet. Because both program parts use the same enable settings,
the sampler will enable both parts at the same time. A list
of settings for the program follow:
Program type: Extended.
Program name: STORM.
Site description: SITE 54.
Units: Length–Ft,FlowRate–gpm,FlowVolume–gal
Mode of Operation: Flowmeter, Flow-Insert, Round, 12"
Bottle kit: 24, 1000-milliliter bottles.
Suction-line length: 5 feet.
Suction head: Auto suction head.
Line rinses: None.
Sampling retries: None.
Part ‘A’ and ‘B’ bottle assignments: Bottles1-6topart‘A’,
bottles 7 - 24 to part ‘B’.
Part ‘A’ pacing: Time pacing, sampling every 5 minutes.
Part ‘A’ distribution: Sequential, 1 sample per bottle.
Part ‘A’ sample volume: 800 milliliters.
Part ‘A’ enable: At least 0.15 inches of rainfall in 30 minutes
and a flow stream level of more than 0.25 feet; once enabled,
stay enabled, sample taken when the sampler is enabled.
Part ‘A’ pause and resumes: None.
Part ‘B’ pacing: Flow pacing, sampling every 2,500 gallons.
Part ‘B’ distribution: Sequential, 1 sample per bottle.
Part ‘B’ sample volume: 500 milliliters.
Part ‘B’ enable: At least 0.15 inches of rainfall in 30 minutes
and a flow stream level of more than 0.25 feet; once enabled,
stay enabled, no sample taken when the sampler is enabled;
first sample taken 20 minutes after the sampler is enabled.
Part ‘B’ pause and resumes: None.
Start time: Delayed start of 1 minute.
