6712FR Refrigerated Sampler

Section 5 Extended Programming

5.6.1Storm Water Runoff Storm water runoff sampling is an ideal application for two-part

Sampling

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.

 

This example assumes that a Rain Gauge and a Bubbler Flow

 

Module are connected to the sampler.

Note

To enable the Bubbler Module programming screens, insert the module before turning on 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 program- mable 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, Flow Rate – gpm, Flow Volume – 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: Bottles 1 - 6 to part ‘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;
