MODE FLOW DIRECTION NOTES
POSFLOW positive flow Accumulates flow in positive direction only
NEGFLOW negative flow Accumulates flow in reverse direction only
NETFLOW positive or negative Adds to positive total; subtracts from reverse total
NETFLOW (default) is best for applications where there may be zero flow for long periods. It minimizes
false Totalizer register increments due to data scatter. Press the <Down Arrow> to accept the default
setting.
To select a Totalizer Mode:
1. Press the <Right Arrow> to access the [Totalizer Mode] option list.
2. Use the <Up or Down Arrow> to move the cursor to the required Totalizer mode.
3. Press <ENT> to store selection.
4.6.10 BATCH/SAMPLE TOTAL
The meter maintains a separate totalizer register for Batching or Sampling applications. Unlike the Flow
Total registers, you cannot access this register directly. It is used for relay control only. If you assign the
system relay to this function, a momentary (200 mS) relay pulse occurs whenever the BATCHTOT
register accumulates a specified liquid quantity. You enter the total flow volume required to activate the
relay, in the [Batch/Sample Total] menu cell. The numeric entry must reflect the selected flow total units.
The [Totalizer Display Scaling] menu cell shows the applicable flow total units. The sign of the Batch/
Sample Total determines positive and negative accumulation.
NOTE: The Batch/Sample total relay requires the same consideration for exceeding the maxi-
mum pulse rate as the TOTCNT relay (see Total Resolution).
To enter a Batch/Sample Volume:
1. Press the <Right Arrow> to activate numeric entry.
2. Use the numeric keys to type the desired Batch/Sample TOT accumulation.
3. Press <ENT> to store data.
4.7 THE DATA SPAN/SET/CAL MENU
This menu becomes available after picking a Meter Type and Measurement Channel. However, some
functions will only be active after the transducers are installed and operating properly.
Use the [Data Span/Set/Cal] menu to set the range for analog outputs and setpoints for Alarm relay
outputs. Additionally, the Calibrate Flow Rate menu allows you to apply external adjustments to the
meter’s intrinsic primary outputs.
4.6.9 TOTALIZER MODE
The Totalizer function operates in any of the modes listed below:
