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 its integral push button display module. 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 simple via integral push button display module |
|
LCD display indicates level in inches, centimeters and percentages |
|
Narrow 2" or 3" beam width for applications with limited measurement space |
|
Fail-safe intelligence and diagnostic feedback for simple troubleshooting |
|
Narrow 3" beam width for applications with limited measurement space |
|
PVDF transducer and NEMA 4X polycarbonate enclosure for corrosive liquids |
|
Automatic temperature compensation for accurate measurement |
