Extreme low power consumption Uses standard Alkaline D-cell batteries
Powerful Windows software
bar graph display
Stingray 2.0 is a compact, battery-powered
logger with an ultrasonic sensor. It data logs level, velocity and
water temperature readings for flow monitoring through open channels, partially full sewer pipes and surcharged pipes.
Use it for flow surveys, I&I studies, stormwater, irrigation water
Hydrodynamic Ultrasonic Sensor
Stingray 2.0 uses a submerged ultrasonic sensor to continuously measure both
velocity and level in the channel. The sensor is a completely sealed ultrasonic unit with no orifices or ports.
It is hydrodynamically shaped
and designed to shed deposits and stringers for reliable operation
in sewage, stormwater and stream flow applications. The QZ02L sensor mounts inside the pipe or at the bottom of an
open channel. No special compounds, tools or hardware are required.
A stainless steel mounting bracket is included.
Standard Alkaline Batteries
With 4 standard Alkaline D-cell
batteries the Stingray 2.0 will operate up to 4 years! These
inexpensive Alkaline 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
stores 130,000 data points including level, velocity and water
temperature. Between readings it powers down to conserve energy.
Stingray 2.0 Confidence Display
You 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.
Greyline Logger software is included with each
Stingray 2.0. Use
this powerful program to view Stingray 2.0 readings in real-time and
to set the logging interval.
Retrieve Stingray 2.0 log files. Data can be viewed in graph or
table format and exported to spreadsheet and database programs.

Stingray 2.0 Introduction in New Orleans
Improvements and key features of the Stingray 2.0
Level-Velocity Logger are shown in the new model launch at
the WEFTEC exhibition in New Orleans.
Greyline Pipe Band Sensor Mounting for Area-Velocity Flow
the easy way - use a stainless steel pipe band for Stingray
sensor mounting. You can install the sensor and tie wrap the
cable in place before you enter the manhole. Then insert the
pipe band into the manhole inlet pipe and tighten the
scissor-jack to expand the band for a friction fit inside
