3.5.18 Suction Head

Time Paced Only. If you selected FLOW PULSES to determine the
sample volume (section 3.5.14), use the Number buttons to enter
the number of pulses required to deliver 10 ml of liquid. This
value establishes the ratio of flow rate to the sample volume at
each event.
For example, consider a time-paced sampler programmed to
collect a sample every hour and you entered "10 ml for every 5
pulses." If the sampler records 100 pulses over the hour, it will
collect a 200 ml sample (100 pulses  5 pulses  10 ml = 200 ml).
Time Paced Only. If you selected ANALOG INPUT to determine
the sample volume (Section 3.5.14), use the Number buttons to
enter the sample volume to be collected at the maximum flow
rate, 20 mA. The sampler will linearly scale sample volumes at
flow rates less than maximum.
Single Bottle Only. Use the Number buttons to type the number
of composite samples to take. Press Enter to accept the value.
Note
If you enter the number zero for sample, it will cause the
sampler to run continuously.
The sampler calculates the maximum possible number of
samples by dividing the configured bottle size (Section 3.3.2) by
the size of each sample volume (Section 3.5.13).
This screen is displayed only if the liquid detector is turned off
(Section 3.3.4). Use the Number buttons to type the suction head
height. Press the Enter button to accept the value.
Suction head height is the vertical distance from the liquid
surface to the pump inlet. To measure the suction head height,
refer to Figure 3-5.
For most applications, Teledyne Isco recommends that you turn
on the liquid detector (Section 3.3.4). The sampler will
automatically calculate the suction head height, typically
resulting in more accurate and repeatable sample volumes.
