The AMETEK Drexelbrook® USonic™ Series instrument is a Two-Wire (Integral) assembly.  Using ultrasonic technology, the USonic™ continuously and accurately measures Level up to a range of 30 feet, or Open Channel Flow.

Integrated software makes measurements on level, distance, volume, or open channel flow easy to configure.
Preset flume and weir characterizations are included in the USonic for over 80 different flumes and weirs.

2-inch Nozzle Mounting
Compact transducer design allows mounting in any 2-inch nozzle. It also allows for a recessed nozzle mounting enabling level to be read to the very top of the vessel.

Automatic Tank Profiling
Automatically ignores most internal obstructions without the need to empty the vessel and without operator intervention.

Ideal for hazardous area installations
Units designed for either Intrinsically Safe or Explosion Proof installations in Class 1 Div.1, Zone 0 environments.
