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 6.1 to initialize.
A. Place QZ02L sensor (flat to the bottom) in a bucket of water
about 6” deep and press the programing button to view the
status page which shows level and velocity. Stir the water to see
a velocity reading.

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
AVFM 6.1 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.
Level Displays the measured level in units selected in
the Units/Mode menu.
Velocity Displays the measured velocity in units selected
in the Units/Mode menu.
Flow Displays the flow rate in units selected in the
Units/Mode menu. The flow is calculated based
on the individual level and velocity data, and
the channel shape and size programmed in the
Channel Setup menu.
Min Flow Displays a read-only value of the minimum
flow cutoff. Any flow rate measured below this
Min Flow will be displayed as 0 on the LCD
display.
Signal Strength Displays the strength of the received Doppler
velocity signal on a 0-100% scale.
Signal Cutoff Displays a read-only value for signal cutoff. If
the Signal Strength is less than the Signal
Cutoff, velocity will be reported as 0. This
setting may need to be adjusted in case of
unstable velocity measurements with no water
moving, or when high levels of industrial noise
are present. The Signal Cutoff can be adjusted
in the Calibration menu.

STATUS (cont.)
Echo Confidence Displays the confidence of level measurement
received from the QZ02L submerged sensor, or
PZ15 level sensor, on a 0-100% scale. This value
is a reflection of the percent of echoes received
from pulses. Example: If 8 pulses are sent from
the level sensor and only 4 echoes are received,
Echo Confidence will report 50%. This does not
mean that the level is inaccurate, but instead
means the level reading could be susceptible
to a loss of reading should the conditions
causing missed pulses gets worse. Like an
increase in solids or bubbles in the flow steam.
24 HR LOG
Press from the MAIN display to view a formatted flow report from
instruments with a built-in data logger. Press to pan through Flow,
Velocity and Level summaries. Press to scroll down one day or
repeatedly to scroll to a specific date. Up to 365 days can be stored for Flow,
Level, and Velocity. Newest date will overwrite the oldest. Press to return to
the main display.
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 Calibration menu.
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

the face of the PZ sensor to the zero level reference
point of the pipe/channel it is installed above. See

Level
Max For QZ02L (submersible, default) level sensor, set the
maximum height the level should reach in the system, in
units configured in the Units/Mode menu. If a Round pipe is
selected in the Channel Setup menu, then this value should
be set to the same value as the inside diameter.
Min For QZ02L (submersible, default) level sensor, set the
minimum height the level should reach in the system, in
units configured in the Units/Mode menu. Minimum level
for the QZ02L sensor is 1 inch, however, this value could be
set to a larger value if you want to ignore levels greater
than 1 inch.
20mA Set the 20mA value for the level analog output, in units
configured in the Units/Mode menu.
4mA Set the 4mA value for the level analog output, in units
configured in the Units/Mode menu.
Lvl Offset For the QZ02L sensor only. Set to 0.00 when sensor is
mounted at the bottom of a channel/pipe. When the sensor
is mounted above the floor, in order to avoid having the
sensor become coated with debris, enter the distance
between the floor and the bottom of the sensor.

CALIBRATION (cont.)
LOE Time Should the level reading be lost because of air or
debris in the system, the LOE Time will cause the meter
to hold the last valid level reading until the LOE Time is
expired, at which point the meter will produce a Loss of
Echo alarm message. Having a LOE Time in the meter
means that intermittent air or debris issues in the
system will not cause the meter to lose flow reading. If
you desire that the meter respond quickly to a Loss of
Echo, set the LOE Time to a low value.
Level Damping
Mode Choose between OFF, FIR (Default), or LOW PASS.
When measured flows are outside the Window of the
running average, the FIR filter will reduce the damping
average so that a fast response can be made to the
sudden change in flow rate.
The LOW PASS filter will ignore measured flow rates
outside the Window, while holding the running
average, until there are enough data points outside the
Window to cause a step-response to the new
measured value.
While measured flows are within the Window of the
running average, both the FIR and LOW PASS filter
behave the same.
Percent Set the damping value for level reading. Lower values
provide fast response to changing levels, and higher
values provide a slower response. Factory default value
is 10%.
Window The Window sets a boundary around the running
average, where if the measured value falls outside the
window, the meter will make a more rapid response to
the new value (FIR), or will hold the last reading until
enough values are outside the window and then make
a step response to the new value (LOW PASS).
Velocity
Min Only shown when Mode = Velocity in the Units/Mode
menu. When measured velocity is less than the Min
Velocity, the reading on the LCD display and output
signals will report 0.

Signal
Cutoff Adjust the setting in percent to suppress industrial
noise from potentially being read as Doppler signals.
When Signal Strength is less than Signal Cutoff, the

Velocity Damping
Mode Choose between OFF, FIR (Default), or LOW PASS.
When measured flows are outside the Window of the

Lower values provide fast response to changing
