Compact... Portable... Battery-Powered

Compact...Portable...Watertight...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 and sewage.

How It Works

Application - Stingray Helps Solve Flow Rate Mystery

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.

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 points

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

Stingray 2.0 Confidence Display

Confidence Display - Use it to check Stingray operationYou 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.



Includes Greyline Logger Windows Software

Greyline Logger software is included with each Stingray. Use this powerful program to view Stingray readings in real-time and to set the logging interval.

Stingray 2.0 Monitors Diversion Water

The Raisin Region Conservation Authority uses a Greyline Stingray to comply with their St Lawrence River diversion flow monitoring agreement.

Greyline Pipe Band Sensor Mounting for Area-Velocity Flow Surveys

Do it 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 the pipe.

Pipe Mounting Bands are available from Greyline in a range of sizes for common pipe diameters.
