DescriptionStingray 2.0 Portable Level-Velocity LoggerProduct Description:The Stingray 2.0 is a compact, portable, and battery-powered level-velocity logger designed for open channel flow measurement. It’s an ideal solution for monitoring flow in open channels, partially full sewer pipes, and surcharged pipes. With no need for calibration and powered by four standard alkaline D-cell batteries, the Stingray 2.0 logs level, velocity, and water temperature data. This device is perfect for applications where flumes or weirs are not available. The ultrasonic sensor continuously monitors flow conditions, offering a reliable and efficient measurement solution.Key Features: Compact, battery-powered design for easy portability and setupUltrasonic sensor requires no calibration and logs level, velocity, and temperatureBuilt-in LCD display provides real-time readings of level, velocity, battery life, and logger memoryUSB output for easy data download and real-time monitoring with included Logger softwareStores up to 130,000 data points with flexible logging intervals (10 seconds to 60 minutes)Specification: Electronics Enclosure: IP67 polycarbonateAccuracy:Level: ±0.25% of rangeVelocity: ±2% of readingDisplay: LCD showing level, velocity, water temperature, battery life, and memory capacityOperating Temperature (Electronics): -20 °C to 60 °C (-4 °F to 140°F)Instrument Setup: Via Greyline Logger software for Windows (site name, logging time interval)Logger Interval Options: 10 sec (15 days)30 sec (45 days)1 min (3 months)2 min (6 months)5 min (1 year)10 min (2 years)15 min (3 years)30 min (4 years)60 min (4 years)Data Logger Capacity: 130,000 data pointsPower: 4 alkaline D-cell batteriesOutput/Communications: USBUSB Cable: 0.9 m (3 ft) shieldedSoftware: Greyline Logger for Windows (supports real-time monitoring, data download/export, graph/data presentation, flow conversion)Approximate Shipping Weight: 4.5 kg (10 lbs)QZ02L Sensor Specifications:Velocity Measurement Range: 0.031 m/s to 3.8 m/s (0.1 ft/s to 12.5 ft/s) in fluids containing bubbles/solids (minimum size: 100 microns, concentration: 75 ppm)Level Measurement Range:Minimum Head: 25.4 mm (1 in)Maximum Head: 4.6 m (15 ft)Operating Temperature: -15 °C to 80 °C (5 °F to 175 °F)Exposed Materials: 316 stainless steel, epoxy resin, polyurethaneSensor Cable: 7.6 m (25 ft) submersible polyurethane jacket, shielded, 3-coaxialSensor Mounting: Includes MB-QZ stainless steel mounting bracketTemperature Compensation: Automatic, continuousWhat’s Included?Stingray 2.0 Level-Velocity Logger with QZ02L Ultrasonic SensorUSB cable (0.9m)Stainless steel sensor mounting bracket (MB-QZ)Greyline Logger Software for WindowsThe Stingray 2.0 is the ideal instrument for flow surveys, I&I studies, CSO monitoring, stormwater runoff, and many other open channel flow monitoring applications. With its user-friendly operation, robust data logging capabilities, and reliable performance, it is the perfect choice for open channel flow measurement in a wide range of conditions.
