4210 Flow Meter

2.9 Step 4 - Reset Totalizer This step allows you to reset the flow meter's internal flow
totalizer. The 4210 can also maintain a separate totalizer for the
time the sampler is enabled through the sampler enabling
feature (step 6). If you select step 4, the following screen will
appear. If you select NO, the flow meter will advance to the next
step. If you select YES, the flow meter will reset the internal
totalizer to zero.
Then, if you have sampler enabling turned on (step 6), the flow
meter will ask you whether you want to reset the totalizer for the
total flow during the time the sampler was enabled. (See step 6
for an explanation of sampler enabling.)
Then:
2.10 Step 5 - Sampler
Pacing
This step determines how the flow meter will signal an asso-
ciated automatic wastewater sampler to take a sample. The flow
meter and sampler must be connected together with a cable. The
flow meter sends flow pulses to the sampler. The sampler uses
these flow pulses as counts. When an appropriate number of flow
pulses has been received by the sampler, it will take a sample. If
you select step 5, the following will appear:
VOLUME will not appear if the flow meter is measuring level
only, or is being used for parameter monitoring. The FLOWLINK
menu option will not appear unless FLOWLINK software is
installed and pacing has been downloaded from FLOWLINK.
If you select DISABLE for sampler pacing, the flow meter will be
effectively disconnected from the sampler. The sampler will run
its program independent of the flow meter. Selection of DISABLE
will also cause the flow meter to advance to the next program
step. If you select VOLUME for sampler pacing, the following
will appear:
Other units of measure, as previously selected, may appear here.
The range for pacing is max. flow ÷ by 100 (minimum) or 10,000
× max. flow (maximum.)
If FLOWLINK appears for sampler pacing, the operation of
sampler pacing has been determined by choices made in
FLOWLINK, Isco's proprietary data acquisition and storage
software. FLOWLINK controls the flow meter remotely, via
phone lines and a modem, or locally with a laptop computer and
cable. If the sampler pacing definition is controlled by
FLOWLINK, it can only be changed through FLOWLINK.
