| EchoSonic™ II Two-Wire Ultrasonic Level Transmitter |
| FlowLine Ultrasonic Level Transmitter Series |
| Item Number: LU28 |
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)
DSP auto adaptive filters enable plug and play operation optimizing signal output filtering and obstacle recognition
Submersible type 6P enclosure is ideal for sump and below grade installations
Configuration is fast and easy via WebCal software and USB adapter
Short 4" or 8" dead band maximizes the measurable filling capacity of the tank
Narrow 3" beam width for applications with limited measurement space
PVDF transducer and 6P polycarbonate enclosure for corrosive liquids
Automatic temperature compensation for accurate measurement
