Open channel flow-meter Greyline Instruments

Continuously monitor, display, totalize and data log flow through any flume or weir. The OCF 4.0 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.
