Portable, Battery-powered

Streamlined Ultrasonic Sensor

Measures Level, Velocity + Temperature

in Open Pipes and Channels

This compact new meter operates on standard alkaline batteries
for extended time periods to data log level, velocity and water
temperature in open channels, partially full sewer pipes and
surcharged pipes a flume or weir. It is designed forwithout
municipal stormwater, combined effluent, raw sewage, irrigation
water and stream flow.

Stingray 2.0 uses a hydrodynamic ultrasonic sensor to accurately
measure both velocity and level in the channel. The submerged
sensor has no moving parts and is resistant to fouling and
corrosion.

Stingray 2.0 measures evel and elocity in open channels or pipes. No calibration is required. The sensorlv

is a completely sealed ultrasonic unit with no orifices or ports. It mounts inside the pipe or at the bottom of a
channel. The watertight electronics enclosure is hung in the manhole or at a convenient location. Sensor,
mounting bracket, batteries, software and cables are included with each Stingray.

Powered by Standard Alkaline
Batteries and Operates up to
Four Years!

With 4 D-cell Alkaline batteries the
Stingray 2.0 will operate up to 4 years!
These low-cost batteries are available in
stores everywhere and with an extremely
low self discharge rate they will reliably
power the energy-efficient Stingray 2.0
for the duration of your flow study.

Stores 130,000 Data Points

Stingray 2.0 stores up to 130,000 data
points including level, velocity and water
temperature. Between readings it
hibernates to conserve energy.

Greyline Logger Software

Powerful Windows software is included free with each Stingray 2.0. Use it to set the logger interval, to download log files
and view Level, Velocity and water temperature readings in real-time.

Greyline Logger will display log files and flow rates in graph and table formats. It will generate flow reports including
minimum, maximum and average flow, calculate flow totals, and convert between common measurement units.

Reporting is easy with Greyline Logger software - you can export charts as image files and export data to use in
spreadsheet or database programs.

Easy to Operate

No calibration is required. Just install the sensor at the bottom of the pipe or channel
and the Stingray 2.0 logs level and velocity readings. Use Greyline Logger software
(included) to set the logging interval, and to view
readings in real-time on your laptop or . StingrayPC

2.0's built-in display lets operators check levelLCD
and velocity rates, remaining battery life and logger
memory.

Built-in Display for Operator Confidence

Operators can check operation with the built-in LCD
bar graph display. It scrolls through level, velocity
and temperature readings, plus remaining battery
and logger storage capacity. The display turns off
automatically after 60 seconds to conserve battery
power.

How it Works

The sensor transmits ultrasonic pulses that travel through the water and reflect off the
liquid surface. To monitor water level, the Stingray 2.0 precisely measures the time it
takes for echoes to return to the sensor.

Velocity is measured with an ultrasonic signal continuously injected into the flow. This
high frequency sound is reflected back to the sensor from particles or bubbles
suspended in the liquid. If the fluid is in motion, the echoes return at an altered
frequency proportionate to flow velocity. The Stingray 2.0 uses this Doppler frequency
shift to accurately calculate flow velocity.
