Decimal Location
In a previous example ("K Factor A and K Factor B (Counter)" on page 25), the K Factor was
divided by ten to display Total and Grand Total in tenths of gallons. Set the decimal point
for the display so that the value displayed using the decimal point is the total in gallons,
and the value displayed not using the decimal point is the total in tenths of gallons. To
make this adjustment, move the decimal location between the lowest and second lowest
digits of the display. Selecting a decimal location of “2” properly sets the decimal point so
that Total and Grand Total in gallons is the “#######.#” value and tenths of gallons is the
”########” value.
Ratemeter
The ratemeter calculates the rate of flow through the meter. It converts the output pulse
from up to two TRICON/E registers into convenient units of measurement by using two
separate scaling factors. The two input rates are scaled and combined into one rate that is
the Total Rate from both inputs. To program the ratemeter portion of the SmartTrol, there
are five parameters you must enter.
K Factor A and K Factor B (Rate)
These scaling factors convert the input pulses into units of volume per unit of time, such as
Gallons per Minute. K Factor A is the scaling factor associated with input A, while K Factor B
is associated with Input B. The SmartTrol first converts input pulses into pulses per second
and then divides the input pulses per second by the K Factor, producing Rate displayed.
The K Factor for Rate to be displayed in units per minute may be determined by the
following formula:
For example, a TRICON/E for a 4” Trident Turbine outputs 1.6 pulses per gallon (reference
the TRICON/E specification sheet).
Thus:
Entering a K Factor of 0.02667 displays the Rate in gallons per minute.
