EchoSonic® II Ultrasonic Level Transmitter with Conduit
Application
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
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 measureable filling capacity of the tank
PVDF transducer and NEMA 4X polycarbonate enclosure for corrosive liquids
Automatic temperature compensation for accurate measurement
The level sensor is configured via our free WebCal PC software and Fob USB adapter. The sensors are offered with and without Fobs. Fobs are universal and can be used to configure any WebCal compatible product. Download your free copy of WebCal in English or Chinese.
