These factors would be applied to the following equation.

From the scenario we can apply the factors to the equation.

At high flow rates, a number below 7 would overfill the bottle. At
low flow rates, a number greater than 16 would collect too little
sample. Therefore, a value should be selected between 7 and 16
pulses.

5.11.3 Calculations when

Using a 700 Series Flow
Module

The same principles discussed in Section 5.11.2 apply. However,
the equations differ slightly because the flow module directly
measures the stream’s flow volumes. The equation for the high
end of the range is:

Using the same scenario the calculations would be:

The equation for the low end of the range is:

The scenario would be applied as:

Therefore, a value should be selected between 709 and 1667
gallons for the given scenario.

5.12 Sampler Enable

Certain external instruments can enable (start) or disable (stop)
a sampler by sending a signal to pin F of the sampler’s flow
meter connector. Teledyne Isco flow meters, flow loggers, and the
Teledyne Isco 1640 Liquid Level Actuator have a programmable
sampler-enable feature that lets them enable or disable the
sampler. You can define the condition (such as level, flow rate,
pH, temperature, percent, rainfall, and I/O) or combination of
conditions that need to be true in order to enable the sampler.
Refer to Figure A-12 in Appendix A for details on programming
sampler enables.
