Greyline Stringray 2.0 Portable Level Velocity Logger

Measures Level, Velocity & Temperature in Open Pipes and Channels

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 Stingray Portable Level Velocity Loggersurcharged pipes. Use it for flow surveys I&I studies, stormwater, irrigation water and sewage. 

Singray 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 hydronamically 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 required. A stainless steel mounting bracket is included. 

With 4 standard alkaline D-cell batteries the Stingray 2.0 will operate for up to 4 years! These inexpensive alkaline batteries are available in most shops and with an extremely low self discharge rate they will relibaly power the energy efficient Stingray 2.0 for the duration of your flow study.

The unit stores 130,000 data points including level, velocity and water temperature. Between readings it powers down to conserve energy.

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 automattically after 60 seconds to preserve battery power.
