Signet 8150 Flow Totalizer
Total K-Factor
The TOTAL K-Factor is a multiple of the FLOW K-Factor. Use it to
program the incremental count size of the Totalizer.
Example: If the flow RATE registers in liters per minute, the
totalizer may be set to 1 (factory standard), so it counts
in 1-liter increments, or it may be set to 1000 so it
counts in 1 kiloliter (1 m
3
) increments.
By converting the Flow K-Factor, the totalizer can
also be set to count in other engineering units. See
page 15 for additional information about Total K-Factor
adjustments.
Example: Change the totalizer from 1-kiloliter increments to
count in 10-kiloliter increments.
1. Hold the ENTER key for 2 seconds, then enter the
SECURITY CODE. The display shows the first item in the
menu, AutoCAL.
2. Press the ▼ key two times to scroll to the Total K-Factor.
3. Press the ► key to select the Total K-Factor for editing.
The first element of the Total K-Factor will begin flashing.
4. Press the ► key six times to advance the flashing element to
the decimal point.
5. Press the ▼ key one time to move the decimal point one
position to the right.
6. Press the ENTER key to return to the menu.
7. Press ▲ and ▼ keys together to exit the menu and return
to normal operation. The display shows "Storing" for a few
seconds, then returns to the normal operating display.

Adjusting the Flow K-Factor
If the Totalizer yields a consistent error, make corrections by either using the AutoCAL function (page 11) or by manually adjusting
the Flow K-Factor by the percentage of error.
A smaller K-Factor increases the flow rate, while larger K-Factors reduce the flow rate.
Example:
•
The Flow K-Factor is set at 480.19 pulses per gallon.
•
The totalizer registers 10 gallons when the actual volume is known to be 11 gallons.
•
The error is 1 gallon divided by 10 gallons , or -10%. (The totalizer is counting 10% low, and the flow rate is reading 10% slow.)
•
Reduce the Flow K-Factor by 10%: 480.19 - 10% = 432.17.
•
Change the Flow K-Factor to 432 pulses per gallon.
The result: The totalizer must count 10% fewer pulses from the flow sensor to register one gallon, so both the totalizer and the flow
rate will increase by 10%.
