OEM MASS FLOW METER: Configuration -2A1
Installation and Operation Guide
INSTRUMENT INSTALLATION
The OEM Mass Flow Meter is an insertion instrument capable of measuring air and gas flow in a wide range of processes. The instrument can be
top or side mounted. The process connection is male 1/4 inch NPT (or 1/2
inch NPT compression fitting). See the installation outline drawing below
for mounting dimensions.
There is an orientation mark etched onto the hexagonal surface of the
element. The flow element must be located with the orientation mark
parallel to flow. Apply an appropriate sealant to the male threads when
installing the flow element and securing enclosure cover. Tighten the
element until it is hand tight. Use a wrench to rotate the element until the
flow arrow on the hexagonal flat is in the direction and parallel to flow,
±2°. If possible, it is recommended the enclosure be located such that the
conduit port is in a downward direction to reduce the opportunitiy of
moisture collecting in the enclosure.

Caution:
Only qualified personnel are to wire or test this
instrument. The operator assumes all
responsibilities for safe practices while wiring or
troubleshooting.
Use the following steps to wire the instrument:
l FCI recommends installing an input power disconnect switch
and fuse near the instrument to interrupt power during
installation, maintenance, calibration, alarm selection and
troubleshooting procedures.
l Ensure the power is off before wiring the instrument.
l Conduit or other protective sheathing should be connected to
the1/2 inch port of the enclosure.
l Unscrew and remove the top cover of the instrument. Lift
the circuit board assembly by pulling up on the white plastic pull
tie wrap. The customer connections are near the top of the
circuit board. Be careful not to stress the wires that are
connected to the circuit board.

l Connect the 4-20mA output terminals as required.
l Connect pulse or alarm output if desired (source or sink mode). Refer to
specifications and setup on following pages.
l Push the board back into the enclosure and replace the top cover.
l Turn power on to operate the instrument.

Configuration options:
4-20mA out: Mass Flow/Volumetric Flow or Temperature
0-10V out: Mass Flow/Volumetric Flow or Temperature (default temperature output range is -40 to 250°F [-40 to 121°C]).
Source out: Pulse (totalizer), or Alarm Function (set-point). Pulse out factorable from 0.001 to 1000 of set flow units, high or low state.*
Sink out: Pulse (totalizer), or Alarm Function (set-point). Pulse out factorable from 0.001 to 1000 of set flow units, high or low state.*
* Default pulse factor is set to 1. For example, if meter is configured in SCFM, then each pulse out will represent 1 SCF. Maximum frequency of
pulse output is 500Hz., therefore, pulse factor must not be set to levels that will exceed this level at maximum flow. i.e. if max. flow = 100 SCFM, @
pulse factor (PF) = 1, pulse rate = 1.667 Hz. @ PF 0.1 = 16.67 Hz, @ PF 0.01 = 166.7 Hz. However, pulse factor 0.001 results in 1667 Hz -- which
exceeds limit of 500 Hz. The pulse sample period is the period for updating the accumalated flow from the internal totalizer. Pulses are output
within this period at a frequency calculated based on the pulse factor setting. In-between pulses are saved and output in the next cycle (pulses are
never lost). The pulse output signals can be independently configured to change from “high” to “low” state or “low” to “high” state. See Table 4.
Setup Interface
All parameters on this meter are set through the RS232 interface connection (RJ11 plug). An FCI model FC88 handheld calibrator or direct
computer interface may be used to access these parameters. The FC88 is powered through the meter and comes with the serial interface cable. If a
computer interface is used, an adapter cable (RJ11 to 9 pin Computer Serial Port) is required and may be obtained from FCI: Part No. 014108-02.
Using Windows Terminal (usually located in Accessories) execute the program by double-clicking on the Terminal Icon.
1. Go to Settings. 2. Click on Communication.
3. Set for COM1 or COM2, 9600 Baud, 8 Bit, and No Parity. Press OK 4. Press the ENTER key to see the Input Mode? prompt.
5. Enter any of the Meters single letter commands to execute a function (reference function menu on following page).
Menu Control and Organization
Most entries require at least two key strokes; a Capital letter and the [ENTER] key, or one or more numbers and the [ENTER] key. All
user entries begin at the Input Mode?< prompt except when the instrument is in the Main Function Mode (just press the desired
function letter and [ENTER] to make an entry).
A user entry is indicated by brackets [ ] being placed around the entry. Y/N refers to Yes (Y), save or change parameter or No (N) do
not save or change parameter unless otherwise specified. Backspaces are made using the backspace [BKSP] key. Some entries are
case sensitive between numbers and letters. Be sure the SHIFT key is pressed to indicate the correct case. A square after the prompt
caret indicates the FC88 is in lower case. A slightly raised rectangle in the same spot indicates the FC88 is in the upper case.
It is recommended that the FC88 be plugged into the instrument before power is applied. If the FC88 is plugged in while the
instrument power is on and the FC88 does not respond, press [ENTER], if there is no response press [P], if there is still no response
Press [N].
Note: The Zero and Span may be changed from the original calibration, provided new values are within the original calibrated range. i.e. if original
calibration was 1 to 100 SCFM (4-20mA), new zero must be equal or greater than 1 SCFM, new span must be equal or less than 100 SCFM.
Some entries require a Factory pass code (Contact FCI Field Service) to continue programming the instrument. The instrument will
prompt the user when this is necessary. Do not change any parameters that require this code unless there is an absolute understanding
of the instrument's operation. The user can not exit some routines unless all entries are completed or the power is recycled.
