FEATURED PRODUCTS

Greyline - Model MantaRay - Portable Area-Velocity Flow Meter

Battery Powered Open Channel Flow Meter Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. The new MantaRay Portable Area-Velocity flowmeter is designed for monitoring stormwater, sewage, industrial effluent, irrigation water and natural streams. The MantaRay uses a submerged ultrasonic sensor which is hydrodynamically shaped and designed to shed deposits and stringers for reliable operation in ...

Greyline - Model OCF 5.0 - Open Channel Flow Monitor

Continuously monitor, display, totalize and data log flow through any flume or weir. The OCF 5.0 includes a non-contacting ultrasonic sensor that mounts just 8' (203.2 mm) above the flowing water. It is accurate (±0.25%) and reliable. There is no obstruction to flow and no fouling. Use the built-in Keypad/menu system to select your flume or weir from the Menu and to choose measurement units (gallons, liters etc.).

FEATURED APPLICATIONS
