CALIBRATION

Stingray does not require field calibration.
It is factory-calibrated to measure level from the bottom of the pipe or channel to the water surface
(maximum 15 ft / 4.5 m), and velocity from 0 to 10 ft/sec (0 to 3.05 m/sec).

Page 6

Stingray 2.0 Level-Velocity Logger

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 Stingray 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.

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).

ENCLOSURE INSTALLATION

Close the Stingray cover and ensure that the sensor cable connector is tightened snugly for a watertight
seal (do not damage the connector by over tightening the coupling). Wipe the enclosure cover gasket
with a clean cloth to remove dirt or grit before closing.

Use a chain or mounting bracket to hang the enclosure from the manhole ladder or any available secure
location. The enclosure should be located above the high water level so that it will not be accidentally
submerged.

Stingray is rated for operation from -20°C to 60°C (-4°F to 140°F). The batteries will not function below
the rated temperature. To prevent overheating, avoid mounting the enclosure in direct sunlight.

Stingray enclosure is rated IP67, watertight and dustproof.

USB CONNECTION

Use the USB Micro-B cable supplied with each Stingray for communication with a PC computer or
laptop.

GREYLINE LOGGER SOFTWARE

Greyline Logger (for Windows) is supplied with each Stingray and is required to download log files and
to set the logging interval of the Stingray data logger. Install on any PC running Windows 7 , 8.1 or XP
with SP3. Requires a PC with USB port and at least 5MB of available disk space.

NOTE: Refer to the Greyline Logger Help menu for complete instructions on using this software. The

following information covers only basic functions of this powerful software program.

START-UP

When you connect to a Stingray for the first time follow this procedure:

1. Connect the Stingray to your PC using mini-USB cable.

2. Use Communication/Connection Setup to configure your PC for communications.

3. Use Real Time Monitor to configure the logging frequency and click Write to initialize

logging, date and time. Date and time are read by the Stingray from your PC.

4. Use Retrieve DataLog to download log files from a Stingray.

CONNECTION SETUP

Under the communication drop-down select

**Scan for USB Instruments** to automatically

detect your Stingray and establish a
connection.

Page 10

REAL TIME MONITOR

Select

Data Logging/Real Time Monitor ON

to
view ‘real-time’ level, velocity and temperature
from the connected Stingray. Readings are updated
every 10 seconds.

Remaining Logger capacity and remaining battery
power are indicated.

LOGGING INTERVAL

Use the
Stingray’s logging interval, then press the

Logging Settings

selector to change the

Write

button to transmit the new setting to the Stingray.

Stingray 2.0 Level-Velocity Logger

IMPORTANT:

Write

action deletes existing log
file and begins a new data log. Download and
save existing log files before executing

Write

.

The Stingray will take measurements for 10
seconds and record the sampled data. It will
then enter a low power "sleep" mode for the
remainder of the interval time. While in sleep
mode, the Stingray consumes minimal power.
This means that the logging interval also
determines the battery life of the instrument.
The table below shows the maximum amount of
time the Stingray can log while at a constant 68 °F (20 °C).

Low temperatures and varying battery
quality will reduce the amount of time
the Stingray can log until the batteries
need to be changed. Because of their
higher power capacity, and better low
temperature characteristics, it is
recommended that only premium
quality Alkaline D-cell batteries
(Energizer E95 or Duracell MN1300)
be used in the Stingray.
