The Greyline Instruments Stingray 2.0 is a compact, battery-powered ultrasonic flow logger. It data logs level, velocity and water temperature
readings for flow monitoring through open channels, partially full sewer pipes and surcharged pipes. The Stingray 2.0 is ideal for flow surveys,
I & I studies, stormwater, irrigation water and sewage applications.
The 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.
The Stingray 2.0 stores 130,000 data points including level, velocity and water temperature. The built-in LCD bar graph display allows for checking
the operation of the meter. Users can quickly scroll 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. The Stingray 2.0 will operate up to 4 years with standard
alkaline batteries.
The Greyline Instruments Stingray 2.0 includes USB output to which users can connect a laptop or PC to view realtime level and velocity readings,
view remaining logger and battery capacity and to set the Stingray 2.0 logging interval.
