7.2.3 How Do I Determine My Calibration Numbers?
When ordered as a complete system, the F-2000 MODEL RT is factory programmed to the flow range you specified when
you placed your order. See section 4.0 for various flow ranges.
Note:
The F-2000 model AO and PC functions will
always
require field programming.
All
F-2000 models will require field
programming when components are purchased separately. See section 7.2 and 7.3.
The following screens are used to input the calibration constants and to turn on or off the various features of the MODEL
RT. The MODEL RT has six different input screens. They are listed in the table below.
Screen No.

Before programming the unit, the following calibration constants must be determined. Remember, when
purchased as a complete system, the model RT is pre-programmed at the factory. No further programming is
necessary.

Step 1
Where would you like your displayed flow rate decimal point located?
Desired Location
=
D (Decimal Rate Factor)
Note:
Four decimal places maximum.
r
XXXXX
= 1
XXXX.X
= 10
XXX.XX
= 100
XX.XXX
= 1000
X.XXXX
=
10000
Enter your D here.
r
Step 2
What time factor would you like to use in your measurement?
Example:
Per Minute =
60 seconds
Per Hour
=
3600 seconds
Per Day
=
86400 seconds
Fill in the amount of seconds you desire here.
Step 3
To determine your flow rate K-Factor, the following information is needed.
a. What size pipe you are going to install this meter on?
inch pipe
b. What schedule pipe are you using?
Sch 40 or
Sch 80 or
Inline
c. What is your flow range?
Low Flow or
Standard Flow (refer to pages 16 & 17)
d. Using the data you specified above, locate your K-Factor from the correct table. Pages 16 & 17.
e. What is your K-Factor?
f. If you are going to be using gallons as your unit of measure, you can go directly to Step 4.
g. To convert K-Factor to other units of measure, use the following formulas:
Ounces
=
K-factor ÷ 128
Liters
=
K-factor ÷ 3.785
Cubic Meters
=
K-factor ÷ 0.003785
Example:
To convert 2” schedule 80 gallons K-factor to
liters, you will use the following formula:
Note: Locate your K-factor off the table on pages 16 & 17..
58.82 (K-factor)
3.785
= 15.54
Your new liters K-factor is 15.54
Write your new K-Factor number here.
