Designed specifically for open channel flow applications, the Greyline PZ15 level sensor can be installed 8" or more above the highest water level. The ultrasonic sensor beam is narrow enough to work on very small flumes and powerful enough for really large applications. It is rated for measurement ranges up to 15 feet.

The Greyline PZ15 sensor mounts above the flowing liquid so there is no fouling and no maintenance is required. It will not be damaged by accidental submersion and it self-tunes to extended cable lengths.
