EchoSonic - Model LU23-29 - Ultrasonic Level Transmitter with Conduit
From Level Transmitters
The general purpose ultrasonic level transmitter provides continuous level measurement up to 32.8’ (10m) 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’ (3m) to 32.8’ (10m)
- Configuration is fast and easy via WebCal software and USB adapter
- Narrow 2” or 3” beam width for applications with limited space
- Short 4” or 8” dead band maximizes the filling capacity of the tank
- PVDF transducer and NEMA 4X PC enclosure for corrosive liquids
- Automatic temperature compensation for accurate measurement
