Entering The K-Factor (Factr); Display Units (Units) - YOKOGAWA YPP6830-AP0-0 Instruction Manual

YPP6830 Explosion-Proof Pulse Input Rate/Totalizer

Entering the K-Factor (Factr)

The meter may be scaled using the K-Factor, or
conversion factor, function. Most flowmeter
manufacturers provide this information with the
device. Enter the K-Factor (Factr) menu and select
the units defined with the K-Factor (example:
pulses/gal), the decimal point with highest resolution
possible, and program the K-Factor value. The meter
will automatically calculate the flow rate using the K-
Factor and the units and time base selected.
•
Performing a K-Factor operation will override any
scaling or calibration programming. Refer to
Scaling & Calibration (SCALCAL) on page 35 for
more information on these programming
methods.
K-Factor Units (FuNiT)
Select the units defined with the K-Factor (example:
pulses/gal). This is usually provided by the flowmeter
manufacturer. This does not set the rate display units,
and only relates to entering the K-Factor. To set or
change the rate display units, see Setting the Rate
Display Units (rateU) on page 24.
The K-Factor unit may be a custom unit (CUST).
Automatic unit conversions are not performed when
the K-Factor unit is set to custom. See page 26 for
information on the Automatic Unit Conversions
feature.
K-Factor Decimal Point (dec. p t)
Set the number of decimal places necessary to enter
the K-Factor value. The decimal point may be set with
up to six decimal places or with no decimal point at all.
Pressing the Right arrow moves the decimal point
one place to the right (including no decimal point).
Pressing the Up arrow moves the decimal point one
place to the left.
K-Factor Value (factr)
Enter the K-Factor value. This value is entered in
Pulses/Unit as defined by the K-Factor Units
parameter. Most flowmeter manufacturers provide this
information with the device.

Display Units (Units)

The Units menu is used to select the display rate units
and time (example: Gal/s) and the display units for
total and grand total.
•
The units selected in this menu are the desired
display units only. The units defined by the K-
Factor of a flow meter are entered in the K-Factor
menu as part of the Factor Unit menu
programming. See K-Factor Units (FuNiT) on
page 23 for details.
•
This allows the display units to be different than
the units defined by the flow meter, or be
changed easily after initial programming. Unit
conversions for rates and totals are performed
automatically by the meter. See Automatic Unit
Conversions on page 26 for details.
The following units may be selected as the base units
for rate, total, and grand total. Time base for rate and
a multiplier for total and grand total units may also be
selected separately.
