FLOW MONITORING (ADVANCED SETUP)
Volumetric flow measurement is available when a level transducer is used for continuous level
sensing in a tank. The Station View
™
unit calculates the volume of liquid based on the level. The flow
is calculated by using the volume and the fill/discharge times. The in-flow and the discharge flow is
measured. The Flow Calc. Level set points are not used for controlling the pump. They are used for
volumetric flow calculation. The flow calculation is based on the area of the tank, the Start Flow Calc.
and Stop Flow Calc. level set points, and the fill and discharge times. Both In-Flow and Discharge flow
are calculated during every cycle.

Tank Diameter:
Enter the tank diameter in Ft.
Flow Calc. Start Level:
See below (in Ft.)
Flow Calc. Stop Level:
See below (in Ft.)
Important notes on flow setup:
Set Flow Calc. Start Level at least 4” below the pump start level.
Set Flow Calc. Stop Level at least 4” above the pump stop level.
The flow accuracy is better with longer cycle times (2 minutes or more).
When using a rectangular tank,
the equivalent diameter would
be:
Example: A 10X10 tank would
equate to a diameter of 11.28.
Enter this value and get the
flow calculations as if it was a
cylindrical tank.
