Portable Level-Velocity Logger

This compact new meter operates on standard alkaline batteries for extended time periods to log level, velocity and water temperature in open channels, partially full sewer pipes and surcharged pipes a flume or weir. It is designed for municipal stormwater, combined effluent, raw sewage, irrigation water and stream flow.

Stingray uses a submerged ultrasonic sensor to continuously measure both Velocity and Level in the channel. The sensor has no moving parts and is resistant to fouling and corrosion.

Stingray measures Level and Velocity in open channels or pipes. No calibration is required. The sensor is a completely sealed ultrasonic unit with no orifices or ports. It mounts inside the pipe or at the bottom of a channel. The watertight electronics enclosure is hung in the manhole or at a convenient location. Sensor mounting bracket, batteries, software and cables are included with each Stingray.

Built-in Display for Operator Confidence - Check Stingray status and performance without connecting to your laptop. Press the display button and the Stingray scrolls through bar graph displays of level, velocity and temperature readings, plus remaining battery and logger storage capacity.

Operators can use the LCD display to check performance at start-up and confirm Stingray readings and signal strength at any time during operation. The display powers off after 60 seconds to conserve battery power.

Greyline Logger Software - Powerful Windows software is included free with each Stingray. Use it to set the logger interval, to download log files and view Level, Velocity and water temperature readings in real-time.

Greyline Logger will display log files and flow rates in graph and table formats. It will generate flow reports including minimum, maximum and average flow, calculate flow totals, and convert between common measurement units.

Reporting is easy with Greyline Logger - you can export charts as image files and export data to use in spreadsheet or database programs.
