CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz. No
adjustments are necessary for voltages within this range. Connect L (Live) N (Neutral) and AC Ground.
Optional DC input model requires 9-32 VDC/10 Watts. Connect to + and - terminals.
Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.
IMPORTANT NOTE: To comply with CSA/UL electrical safety standards, AC power input and relay
connection wires must have conduit entry to the instrument enclosure. Installation requires a switch,
overcurrent fuse or circuit breaker in the building (in close proximity to the equipment) that is marked
as the disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel
should access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.
QUICK BENCH TEST:
Connect Sensor as shown on next page, then Power. Test operation of the UFM-50 by holding the
sensor in one hand and rubbing your thumb or fingers briskly across the face (plastic surface) of the
sensor. Allow 15 seconds for the UFM-50 to process the signal and display a flow value.

MAIN DISPLAY
The main display shows the units selected from the Units/Mode menu, flow or
velocity rate being measured, totalizer and relay states. The UFM-50 will start-up
with this display.
MESSAGE ICON
Press from the main display to view status of the data logger and error/
warning messages provided by the instrument. The Message Icon will appear on
the main display if error messages are being generated by the instrument. Press 
to return to the main display.
Sensor Displays the status of the sensor hardware. Even with
the sensor disconnected or shorted, the flowmeter will
display Good. To check sensor integrity, use the sensor
resistance test procedure on page 28. If HardwareFault
is detected, navigate to the Configuration page in the
Main Menu to determine which circuit board is not
communicating.
STATUS
Press from the main display to view instrument status. Velocity will be
displayed in ft/sec or m/sec.
Velocity Displays the measured flow velocity in units selected in
the Units/Mode menu.
Flow Displays the measured flow rate in units selected in the
Units/Mode menu.
Min Flow Displays the minimum flow rate setting. This value is
read-only. The Min Flow can be changed in the
Calibration programming menu. A measured Flow
value below the Min Flow value will display as 0 flow
on the meter’s LCD display.
Signal
Strength Displays the strength of the received Doppler signal on
a 0-100% scale.
Signal Cutoff Displays the signal cutoff. This value is read-only. The
Signal Cutoff can be changed in the Calibration
programming menu. If Signal Strength is less than
Signal Cutoff, the meter will report 0 velocity and flow
on the LCD display. Setting may need to be adjusted in
the case of unstable flow near zero, or when high levels
of industrial noise are present.

24 HR LOG
Press from the main display to view a formatted flow report from instruments
with a built-in data logger. Press to scroll down one day or repeatedly to scroll
to a specific date. Up to 365 days can be stored. Newest date will overwrite the
oldest. Press to return to the main display.
IMPORTANT: Inserting a USB drive into the meter while on this screen will
transfer 24 HR Log data to the USB drive in .csv format.
PASSWORD
The Password (a number from 0000 to 9999) prevents unauthorized access to the

From the Main Display press the key to get to Password. Factory default
password is 0000 and if it has not been changed, this screen will be bypassed
completely.
A new password can be stored by going to the Special Functions New
Password menu.
If a user password is required, press to place the cursor under the first digit and
or to set the number, then to the second digit, etc. Press or to proceed
to the Menu Selections screen.
MENU SELECTIONS
The Menu selections page is used to navigate to specific menus which are
described in more detail on the following pages.
