2.5 How Does the Sampler Work?

When the sampler takes a sample, it draws liquid through the

strainer and suction line to the pump tube. The liquid flows

through the pump tube and past the liquid detector, which senses

the liquid. From the detector, the liquid follows the pump tube

through the pump to the bulkhead fitting and then through the

discharge tube to the sample bottle.

A typical sampling cycle consists of:

1. The sampler moves the distributor arm over the bottle that

is to receive the sample.

2. The pump reverses for the pre-sample purge.

3. The pump direction changes, filling the suction line.

4. When the detector senses liquid, the sampler begins mea-

suring the sample.

5. After depositing the sample, the pump again reverses for

the post-sample purge.

Sampling cycles vary somewhat according to program settings

for distribution. The sampler can move the distributor arm

clockwise and counterclockwise, making a number of distribution

methods possible. (In this manual, the words “sample event”

refer to a full sampling cycle for any distribution.)

Note

• The suction lines will float when filled with air during the purge cycles and when depths exceed the

listed ratings. Secure the suction lines when sampling at depths exceeding the maximum ratings.

• All strainer dimensions are in inches.

• Teflon suction line is compatible only with the 3/8 stainless steel strainer.
