The MODEL RT is the base unit of the F-2000 flow monitoring system. Fluid flowing through the pipe causes the
paddlewheel to spin. Pulses generated by the spinning paddlewheel are counted and multiplied by scaling factors. The
resulting flow rate amounts and total flow amounts are displayed on the LCD readout. Pressing the enter button located
on the front panel toggles the display between flow rate and total flow or allows entry into the programming mode.
Pressing the clear total button while the total flow value is displayed will return the total to zero (must be activated in the
programming mode - not the factory default setting). A small icon will light at the bottom of the LCD indicating the mode
being displayed.
The MODEL PC includes all of the features of the MODEL RT as well as a relay which can be used to switch external
electrical equipment when user programmed setpoints are reached. The relay must be assigned to respond to either the
rate value for rate alarm applications (rate mode), or to the total value for batching or proportional feed applications (batch
mode). Only one may made be used at any one time. When assigned to the batch mode, the display can be toggled to
show four different values, the rate of flow, total flow, current batch number or current batch total, by pressing the enter
button located on the front panel. A small icon will light at the bottom of the LCD display indicating the mode being
displayed. The model PC is described in a separate instruction manual.
The MODEL AO includes all of the features of the MODEL RT as well as a 4-20mA or 0-10VDC output signal which is
proportional to the flow rate value. This mode is always active although the output value can not be displayed on the LCD.
A small icon will light indicating the mode is active. The model AO is described in a separate instruction manual.
The MODEL AP includes the features of all three F-2000 models, the RT, PC, and AO.

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.

RATE 2
RATE 3

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.
Toggle Battery Saving mode - on / off (factory default: off)
Toggle front panel Clear Total button - on (enabled) / off (disabled) -- (factory default: off)
Step 4 Calculate your Rate Scale Factor (S ) using the following formula.
D from Step 1, Seconds from Step 2, K-Factor from Step 3.

Step 6 Determine your Total K-factor.
Your Total K-factor and Flow Rate K-factor are the same if the same units (i.e., Gallons, liters, etc.) Are
displayed for both. However, you can use a different unit of measure for your total display. Follow the
instructions in step 3-g to convert to a different Total K-factor unit.
Write your Total K-factor here.
Step 7Calculate your Total Scale Factor (S ) using the following formula.
The F-2000 requires very little maintenance, however, some conditions will cause increased wear or
possible damage to the unit.
!
Periodically remove the sensor assembly from the pipe fitting and inspect the meter for signs of wear
and obstructions. Clean the paddle of any foreign objects. Replace the paddle and axle if worn.
!
Although the meter is capable of operating at the high end of the flow range, continuous use at very
high flow rates (upper 25% of the calibrated flow range), is not recommended. The paddle and axle life
is related to the rate of flow and the fluid being measured. Corrosive fluids moving at high flow rates
will cause increased wear requiring frequent inspection and maintenance. Ceramic, titanium or nickel
axles are available for extreme corrosive environments.
!
Although the F-1000 is designed to withstand outdoor conditions, a cool, dry location where the unit can
be easily serviced is recommended. The life of the LCD display will be severely reduced when
installed in direct sunlight. Do not install the meter so that the LCD is in direct sunlight.
!
O-rings should be inspected periodically. Immediately replace the o-rings at any sign of wear, swelling,
cracking or discoloration.
!
Battery operated models. Replace the four AA batteries every 12 months. The program memory will
not erase when replacing the batteries. The unit will function normally for approximately 2 minutes
while replacing the batteries. To replace the batteries, open the front panel of the enclosure by
removing the four Phillips screws. After replacing the batteries, be sure the foam insert is in place
before closing the front panel.
!
Test the electronics by removing the sensor assembly from the pipe fitting and spinning the paddle by
hand. If a reading does not appear in the display window, replace the batteries. If a reading still does
