• 9400 liter (2.5 gallon) polyethylene composite bottle
with unlined cap
1.4 Power Options
The sampler is powered by a 12 VDC power source, either a
rechargeable nickel-cadmium battery, a lead-acid rechargeable
battery, or an AC-powered 12-VDC regulated supply.
CAUTION
If you use a 120 or 240 volt AC-connected Power Pack, the AC
line cord is the "Disconnect Device." Always install the sampler
with the line cord and plug visible and readily accessible, so
that power can be disconnected easily.
For complete information on power options and their mainte-
nance, consult the Teledyne Isco
Power Products Guide , which
was also shipped with your sampler. You can order additional
copies of the
Power Products Guide by contacting Teledyne Isco’s

1.5.1 Isco Flow Meters
The 4200 Series Flow Meters, 2100 Series Flow Modules, and
4100 Series Flow Loggers, and UniMag Closed-Pipe Flow Meters,
are collectively called “flow meters” in this manual. The 3700
Series will accept flow pulses from all Isco Flow meters for
flow-paced sampling. Isco Flow meters and flow loggers are
equipped with a sampler-enable feature. The 4200 Series Flow
Meters and 4100 Series Flow Loggers can inhibit a 3700 until the
level of the flow stream reaches a predetermined height or “set
point.”
When the flow stream reaches that height, the flow meter
enables the sampler and starts the sampling routine. If the level
of the stream falls below the set point, the flow meter can disable
the sampler and halt the routine.
