3700 Portable Samplers

Section 4 Options and Interfacing Equipment

4-5

Teledyne Isco also offers a connector prewired to a 22-foot
(6.7-meter) cable that terminates in two wires. The black wire is
connected to pin A; the white wire to pin C.

Note that you will be unable to communicate anything other
than the flow pulse contact closure with a non-Isco Flow meter.
The non-Isco Flow meter will not be able to interpret event and
bottle number information.

If the flow pulse generated by the contact closure on the flow
meter is not compatible with Teledyne Isco’s standard, contact
Teledyne Isco’s Special Products Department for an appropriate
interface device.

4.3.3 4-20 mA Flow Signals

The 3700 Sampler can also be used with flow meters having
other types of outputs, for example, a 4 to 20 mA output directly
proportional to the flow rate. However, these flow meters require
a special interface device to convert their output signal to one
compatible with the 3700 sampler.

The

4–20 mA Sampler Input Interface

converts 4 to 20 mA

output signals from both non-Isco Flow meters and closed-pipe
flow meters to flow pulses acceptable to the 3700 Sampler.

Figure 4-3 4-20 mA Sampler Input Interface

4.3.4 1640 Liquid Level

Actuator

The Liquid Level Actuator is an accessory that begins a sampling
routine when the liquid level of the flow stream reaches a prede-
termined height. The actuator inhibits sampling according to
flow levels; that is if the level of the flow stream falls below the
actuator’s probe, the actuator will inhibit sampling until the level
again rises to contact the probe.
