4.3.2 Non-Isco Flow Meters You can connect certain non-Isco Flow meters directly to a 3700
for flow-paced sampling. The flow meter must have an isolated
contact closure of at least 25 milliseconds to provide acceptable
flow pulses to the sampler. The frequency of the contact closure
must be directly proportional to total flow. Teledyne Isco offers
both a connector and cable clamp to connect a non-Isco Flow
meter to the 3700 samplers. Connect the flow meter pulse output
to the A and C pins of the 6-pin Flow Meter connector on the
3700 (Figure 4-2). Refer to your flow meter’s instruction manual
for further details.
