CONNECTIONS:
POWER INPUT: 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: 9-32 VDC. 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.
Note: User replaceable fuse is 2 Amp 250V (T2AL250V).
FUNCTION TEST:
Connect the sensor to the TDCR terminals as shown below, then apply
power. Allow 30 seconds for the AVFM 5.0 to initialize.
A. Place QZ02L sensor (flat to the bottom) in a bucket of water
about 6” deep and select Level mode (from
UNITS/MODE menu) to see a level reading.
B. Select Velocity mode and stir the water to see a
velocity reading.

KEYPAD SYSTEM
The AVFM 5.0 uses a menu system. Arrows show the four directions to leave a menu box. Pressing a
corresponding keypad arrow will move to the next item in the direction shown. Move the cursor
(underline) under numerals and increase or decrease numerals with the and keys.
To store calibration values permanently (even through power interruptions), press .

RUN
The main display shows the units selected from the Units/Mode menu,
Flow or Velocity rate being measured, TOTALIZER and RELAY states. The
AVFM 5.0 will start-up with this display and will return to this screen after a
timeout if keys are not pressed in other menus.
MESSAGE
Press from the RUN display to view temperature measurement, status of the
data logger and error/warning messages provided by the instrument. The word
Message will appear on the RUN display if error messages are being
generated by the instrument. Refer to the manual section Error/Warning Messages
for a description. Press to return to the main display.
STATUS
Press from the RUN display to view instrument status.
Velocity Will be displayed in ft/sec or m/sec.
Level Is displayed in the selected units.
Tot Displays the current totalizer reading.
Signal Cutoff Adjust the setting in percent to suppress flow readings
at zero flow when fluid swirling or pipe vibration may
cause the instrument to continue reading. Example:
Signal Cutoff at 5% will force the display
and outputs to zero when signal strength drops below
5%.
Signal Strength Displays percentage of signal being received by the
ultrasonic sensor.
EC Displays level measurement Echo Confidence

24 HR LOG (Data Logging option only)
Press from the RUN display to view a formatted flow report from instruments
with a built-in data logger. Press to pan through Level, Velocity and
Flow summaries. 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.
PASSWORD
The Password (a number from 0000 to 9999) prevents unauthorized access
