EchoSonic II LU23/27/28/29 Ultrasonic Level Transmitter
Brand: FlowlineThe general-purpose ultrasonic level transmitter provides continuous level measurement up to 32.8 feet (10 meters) with a 4-20 mA signal output, and is configured via our free Webcal software.
This non-contact liquid level sensor is ideally suited for corrosive, ultrapure, sticky or dirty liquids, and is broadly selected for bulk storage, day tank, lift station and process tank level applications.
Features- Offered in 4 measurement ranges from 9.8 feet (3 meters) to 32.8 feet (10 meters)
- DSP auto adaptive filters enable plug and play operation optimizing signal output filtering and obstacle recognition
- Configuration is fast and easy via WebCal software and USB adapter
- Narrow 2" or 3" beam width for applications with limited measurement space
- Short 4" or 8" dead band maximizes the measurable filling capacity of the tank
- PVDF transducer and NEMA 4X polycarbonate enclosure for corrosive liquids
- Automatic temperature compensation for accurate measurement
