Ultrasonic level sensor AS-ULM

for solidsfor liquidsRS-485

Product Overview
Ultrasonic Level Meter AS-ULM is a split-design, non-contact sensor for continuous level measurement of liquids and solids. The transducer is rated IP68 for submerged use while the separated transmitter is accessible for installation and maintenance. Typical output is RS485 (default) with accuracy between 0.5% and 1.0% and a measurement range from 30 to 60,000 mm.
