Flow Paced Sampling Program - Teledyne 4700 Pocket Manual

3.6.3 Flow Paced Sampling Program

This example shows how to program the
sampler to collect a 100 ml sample every 10,000
gallons of liquid that has passed the sampling
point. The sampler will composite the samples
in one of its two 10-liter bottles. The sampling
program should begin counting the elapsed flow
at midnight and run continuously.
Because the program runs continuously, the
sampler will fill one bottle in a day, then fill the
other bottle the next day. Daily, an operator
would only need to exchange the completed
bottle with an empty one and the program
could run indefinitely. However, service
intervals should be planned to replace worn
pump tubes.
This example assumes that the sampler has
been configured with 2 bottles (sections 2.3.4
and 3.3.2). It also assumes the flow meter
connected to the sampler (sections 2.7) sends a
flow pulse every 1,000 gallons.
