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.

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.
