The general purpose ultrasonic level transmitter provides continuous level measurement up to 32.8' with a 4-20 milliampere 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. Automatic temperature compensation for accurate measurement. Configuration is fast and simple with the scrolling single layer menu, 3-button interface and 6-segment LCD display. Troubleshooting is easy with our powerful setup and diagnostic modes. Setup displays the transmitter’s calibration set points and diagnostics provides users with a snapshot of the installed sensor performance in the application. Range: 12" to 32.8'.
