Compact ... Portable ... Battery-powered

Stingray 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. 

Stingray 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 mounts inside the pipe or at the bottom of a rectangular channel. No special compounds, tools or hardware are required.

Use it to check Stingray operation Stingray Confidence Display

You can check Stingray 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.

  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.

For semi-permanent installations...

Check out the AVFM 5.0 Area-Velocity Flow Meter for applications in partially filled pipes and channels. It displays and transmits flow, level and velocity with three 4-20mA outputs.
