One of the uses of the 4250 Flow Meter is to control a sampler in
a flow-paced sampling mode. Flow-paced sampling means that
the flow meter is programmed to signal the sampler to take a
sample after a specific volume of flow has passed through the
flow stream, rather than after a particular period of time. In this
mode, the sampler and flow meter will be able to compensate for
varying flow rates. The 4250 Flow Meter may be used with any of
the Isco Wastewater Samplers listed in Section 1.
An optional 25 foot (7.6 m) long connect cable is available to
connect the flow meter to the sampler. Attach the six-pin female
connector on the cable to the Sampler connector on the side of the
flow meter. (This is the second connector from the top.) Attach
the connector on the other end of the cable to the Flow Meter
socket on the sampler. The flow meter will then be connected to
the sampler's power supply, and the sampler will be able to
receive flow-proportional signals from the flow meter. Refer to
the sampler manual for further details.
