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 sensor terminals as shown on next page, then
apply power. Allow 30 seconds for the AVFM 5.0 to initialize.

MAIN DISP LAY
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.
MESSAGE ICON
Press from the main display to view temperature measurement, 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.
STATUS
Press from the MAIN display to view instrument status.
Velocity Will be displayed in ft/sec or m/sec.
Level Is displayed in the selected units.
Displays the current totalizer reading.
Tot
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
Relays 1 2 3 4 5 6 Energized relays will display with reversed font eg:
