KEYPAD SYSTEM
The MantaRay 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 .
BATTERY
- A built-in rechargable NiMH battery supplies power for 48 hours continuous operation when fully
charged.
- Display brightness is adjustable to conserve power.
- The MantaRay will switch off automatically when the battery is fully discharged.
- Full charge requires approximately 6 to 9 hours charging.
- Sleep mode extends battery life for long term data logging (30 days for 5 minute logging).
CHARGING BATTERY
A 16V AC-DC power module is supplied for battery charging and continuous use. Full charge requires
6-9 hours when fully drained. Solid battery icon and/or full charge adapter icon indicates when battery is
fully charged.

Press from the main display to view temperature measurement, status of the
data logger battery 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.
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.

INSTALLATION - SENSOR LOCATION
1. Choose a sensor mounting location where silt or deposits are least likely to accumulate.
2. For best results flow should be evenly distributed across the channel and relatively free of turbulence.
(The MantaRay is very effective at averaging level and velocity readings in turbulent conditions, but
best accuracy and response time is achieved with evenly distributed flow.)
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 QZ02L sensor with the
stainless steel bracket and hardware
supplied. Ensure that the sensor is
parallel to the water surface (check with
a level). Mount with the tapered end of
the sensor pointing upstream and the
sensor cable pointing downstream.
Clip or tie wrap the sensor cable securely
to the pipe or channel wall.
Note: The mounting bracket is designed
to release the sensor if weeds or rags are
caught by the sensor.
