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 AVMS 5.1 to AVQZ3 using interface cable.
Connect sensor to the sensor A and D terminals as shown on page 6,
then apply power. Allow 30 seconds for the AVMS 5.1 to initialize.
A. Place the 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 velocity
reading(s).

STATUS
Press from the MAIN display to view instrument status.
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%.

INSTALLATION - SENSOR LOCATION
1. Choose sensor mounting locations where silt or deposits are least likely to accumulate.
2. For best results the three AVMS submerged velocity sensors should be positioned to obtain average
velocity across the channel width.
3. Avoid vertical drops, obstructions or elbows immediately up and downstream from the sensor. Locate
the QZ02L sensor at least 10 times maximum Head (level) and 10 times the channel width from these
flow disturbances.
4. The QZ02L submerged level-velocity sensor requires a minimum water level of 1 in. (25.4 mm).
QZ02L VELOCITY-LEVEL SENSOR MOUNTING
Mount the three QZ02L sensors with
stainless steel brackets and hardware
supplied. Ensure that the one QZ02L
sensor that is monitoring level is parallel
to the water surface (check with a level).
Mount with the tapered end of the
sensors pointing upstream and the sensor
cable pointing downstream.
Mount QZ02L velocity sensors at or
near the bottom of the channel or pipe in
positions where they will be
continuously submerged. Position where
silt or solids will not build up on the
sensors.
Clip or tie wrap the sensor cables
securely to the pipe or channel wall.
