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.

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).

ENCLOSURE INSTALLATION
Locate the enclosure within 20 ft (6 m) of the sensor (up to 500 ft -150 m optional). The enclosure can
be wall mounted with the four mounting screws (included) or panel mounted with Option PM Panel
Mount kit from Greyline Instruments.
Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to
overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing,
Option TH Enclosure Heater and Thermostat is recommended. Seal conduit entries to prevent moisture
from entering enclosure.
NEMA4X (IP66) WITH CLEAR COVER
1. Open hinged enclosure cover.
2. Insert #8 screws (supplied) through the four enclosure mounting holes
to secure the enclosure to the wall or mounting stand.
Additional conduit holes can be cut in the bottom of the enclosure with a
hole saw or Greenlee-type hole cutter.
DO NOT make conduit/wiring entries into the top of the enclosure.
Note: This non-metallic enclosure does not automatically provide
grounding between conduit connections. Grounding must be provided as
part of the installation. Ground in accordance with the requirements of the
National Electrical Code. System grounding is provided by connecting
grounding wires from all conduit entries to the steel mounting plate or
another point which provides continuity.

FIELD TROUBLESHOOTING
The AVMS 5.1 uses an ultrasonic level sensor to determine channel AREA and an ultrasonic Doppler
sensor to measure flow VELOCITY.
The QZ02L sensor combines both sensors in one housing.
An optional configuration uses the PZ12-LP “down-looking” level sensor and a QZ02L-DP velocity
sensor.
To troubleshoot the AVMS 5.1, verify correct operation of LEVEL and VELOCITY measurements
separately.
Note: Selecting “Defaults” in the SPECIAL FUNCTION menu will return the instrument to
“as-shipped” factory settings.

SENSOR CABLE RESISTANCE TEST
Unplug the green sensor terminal from the Doppler board and connect the sensor wires as shown. With a
multimeter, perform resistance checks for each set of wires. One single loose terminal may cause false
readings.
Test across shield and core of each wire: TMTR (black/white) and RCVR (black). Resistance should be
approximately 82.5K ohms for any cable length. High readings indicate an open circuit and low readings
indicate a short or partial short in the sensor cable.

1. Rinse sensor and cable to remove debris.
2. If the sensor has been exposed to sewage, immerse both sensor and cable in a solution of 1 part
household bleach (Javex, Clorox etc.) to 20 parts water for 5 minutes. Important: do not immerse
open end of sensor cable.
3. Dry with paper towels and pack sensor and cable in a sealed plastic bag.
4. Wipe the outside of the enclosure to remove dirt or deposits.
5. Return to Greyline for service.

APPENDIX A – OPTIONS
EXTRA SENSOR CABLE
(OPTION VXC)
Each Greyline AVMS 5.1 flow meter includes 25 ft. (7.6 m), 50 ft. (15 m) or 100 ft. (30 m) tri-coaxial
sensor cable. This cable is shielded from electrical interference and is watertight with a polyurethane
jacket. Additional cable and Cable Junction Box (Option JB2X or JB4X) may be ordered with the Flow
Meter, or the cable may be spliced and extended up to 500 ft (152 m) total length as required during
installation. No adjustment is required when the sensor cable is extended or shortened. Use only
Greyline tri-coaxial VXC shielded cable, or run three RG174U coaxial cables in a metal conduit.
Extended sensor cable can be installed in conduit for mechanical protection. Recommended installation
with a junction box is illustrated below:

ENCLOSURE HEATER AND THERMOSTAT - Option TH
Instruments can be factory-equipped with an Enclosure Heater and Thermostat or the module can be
customer-installed. The Thermostat is factory set to turn ON at 40°F (4.5°C) and OFF at 60°F (15.5°C).
Power consumption is 15 Watts.
Please note: Only the AVMS 5.1 enclosure can be fitted with the Enclosure Heater and Thermostat
module. The remote AVQZ3 enclosure does not support a heater option.
