EchoSonic LU23-29 Ultrasonic Liquid Level Sensor Transmitter
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, sticky or waste liquids, and is selected for bulk storage, tanker truck, day tank, process tank, waste sump, neutralization tank, open channel, chemical feed and clarifier applications.
Features & Benefits
Features:
- Offered in 4 measurement ranges from 9.8’ (3m) to 32.8’ (10m)
- 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 measurable filling capacity of the tank
- PVDF transducer and 6P polycarbonate enclosure for corrosive liquids
- Automatic temperature compensation for accurate measurement
