Changing Units of Volume
You can modify the K Factor so that the displayed values of Total or Grand Total are in
units of measurement instead of gallons. To change the display from gallons to cubic feet,
multiply the K Factor by 7.4805, which is the number of gallons per cubic foot. To change
the display from gallons to cubic meters, multiply the K Factor by 264.172, the number of
gallons per cubic meter.
In the previous example of the 4” Trident Turbine, to display Total or Grand Total in cubic
feet, multiply the K Factor of 1.6 pulses per gallon by 7.4805. So:
1.6 pulses / gallon x 7.4805 gallons / cubic foot = 11.9688 pulses / cubic foot
Setting the K Factor to 11.9688 displays Total and Grand Total in cubic feet for the 4”
Trident Turbine.
Datalost
If the value of the K Factor is less than .0001, or the factored counts exceed 30,000 per
second, the counter is unable to keep up with the counts and “DATALOST” appears on the
display during SmartTrol operation. If this message appears, increase the value of the
appropriate K Factor.
Reset to Zero or Set to Preset
The selection of the counter operation depends on the application. For simple monitoring
of volume through the meter, select “Reset to Zero”. This mode is normal for volume
measurement where the Total is reset to zero, then increases, as water passes through the
meter.
For some batching applications, it is preferable to inject a fixed amount of water into some
process. It may be easier to track the process if, upon reset, the Total is set to the batch
volume and decremented as the water is injected. The end point of the batch, zero, is the
same no matter the injected volume. Select "Set to Preset" to choose this mode for the
counter operation.
Automatic or Manual Reset
This function determines what happens to the Total upon reaching the end point (preset
value for counting up, zero for counting down). If you select “Manual” mode, the Total
continues to update after reaching the end point. The reset, either from panel or external
input, must be active to reset the counter. In the Automatic mode, the counter is
automatically reset upon reaching the endpoint (reset to zero if counting up, reset to the
preset value if counting down).
