1.0 Introduction
The FTB300 is designed to display flow rate and flow total on a six digit LCD display. The meter can measure bi-directional flows in either vertical or horizontal mounting orientation. Six flow ranges and four optional pipe and tubing connections are available. Pre-programmed calibration K-factors can be selected for the corresponding flow range or a custom field calibra­tion can be performed for higher accuracy at a specific flow rate. The meter
is factory programmed for the correct K-factor of the body size included with the meter.

4.1 Wiring Connections
On sensor mounted units, the output signal wires must be installed through the back panel using a second liquid-tite connector (included). To install the connector, remove the circular knock-out. Trim the edge if required. Install the extra liquid-tite connector.
On panel or wall mounted units, wiring may be installed through the enclosure bottom or through the back panel. See below.

5.0 Operation
5.1 Theory of operation
The FTB300 is designed to measure the flow rate and accumulate the total volume of a fluid. The unit contains a paddle wheel that has six (6) through holes to allow infrared light to pass through, a light-detecting circuit and a LCD-display electronic circuit.
As fluid passes through the meter body, the paddle wheel spins. Each time the wheel rotates a DC square wave is output from the sensor. There are six (6) compete DC cycles induced for every revolution of the paddle wheel. The frequency of this signal is proportional to the velocity of the fluid in the conduit. The generated signal is then sent into the electronic circuit to be processed.
The meter is factory programmed for the correct K-factor of the body size included with the meter.
The flowmeter includes the following features:
! Displays either the flow rate or the accumulated total flow. ! Provides a pulse output signal that is proportional to the flow rate. ! Provides an open collector alarm output signal. Active low at flow rates
above the user programmed value.
! Provides user selectable, factory preset calibration k-factors. ! Provides a field calibration procedure for more precise measurement. ! Front panel programming can be disabled by a circuit board jumper pin.

Enter Button (right arrow) -
! Press and release - Toggle between
Rate, Total, and Calibrate screens in the run mode. Select program screens in the program mode.
! Press and hold 2 seconds - Enter
and exit program mode. (Automatic exit program mode after 30 seconds of no inputs).
Clear/Cal (up arrow) -
! Press and release - Clear total in the run mode. Scroll through and Select
options in the program mode.
5.3 Flow stream requirements
! The FTB300 can measure fluid flow in either direction. ! The meter must be mounted so that the paddle axle is in a horizontal
position - up to 10 off the horizontal is acceptable.
o
! The fluid must be capable of passing infra-red light. ! The fluid must be free of debris. A 150 micron filter is recommended -
especially when using the smallest body size (S1), which has a 0.031” through hole.

6.0 Programming
The FTB300 uses a K-factor to calculate the flow rate and total. The K­factor is defined as the number of pulses generated by the paddle per volume of fluid flow. Each of the six different body sizes have different
operating flow ranges and different K-factors. The meter is factory programmed for the correct K-factor of the body size included with the meter.
The meter’s rate and total displays can be independently programmed to display units in milliliters (ML), ounces (OZ), gallons (GAL), or liters (LIT). Rate and total can be displayed in different units of measure. The factory programming is in milliliters (ML).
The meter’s rate display can be independently programmed to display time base units in minutes (Min), Hours (Hr), or Days (Day). The factory programming is in minutes (Min).
For greater accuracy at a specific flow rate, the meter can be field cali­brated. This procedure will automatically over-ride the factory K-factor with the number of pulses accumulated during the calibration procedure. The factory default settings can be re-selected at any time.
6.1 Field Calibration
Any body size/range can be field calibrated. Calibration will take into account your specific application’s fluid properties, such as viscosity and flow rate, and increase the accuracy of the meter in your application.
The Body Size/Range must be set for “S0” to enable the calibration mode. Follow the programming instructions on pages 10 & 11 to reset the Body Size/Range and perform the calibration procedure.

The meter should be installed as intended in the application.
The amount of fluid that flows through the meter during the calibration procedure must be measured at the end of the calibration procedure.
Allow the meter to operate normally, in the intended application, for a period of time. A test time of at least one minute is recommended. Pulses will accumulate in the display. After the test time period, Stop the flow through the meter. The pulse counter will stop.
Determine the amount of fluid that passed through the meter using a graduated cylinder, scale, or other method. The measured amount must be entered in calibration screen #4 “MEASURED VALUE INPUT.”
