Flowline-EchoSonic® II Ultrasonic Level Transmitter with Cable ( Model: LU23/27/28/29 )

Application:

Offered in a type 6P enclosure with cable interface, 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 & play operation optimizing signal output filtering & obstacle recognition

Submersible type 6P enclosure is ideal for sump and below grade installations

Narrow 2" or 3" beam width for applications with limited measurement space

Configuration is fast and easy via WebCal software and USB adapter

Short 4" or 8" dead band maximizes the measureable filling capacity of the tank

PVDF transducer and 6P polycarbonate enclosure for corrosive liquids

Automatic temperature compensation for accurate measurement
