ultrasonic level switch / for liquids / threaded / IP66

ASL instrument is designed for marine and on-land applications for liquid d?tection, pump control, water ingress alarm Systems, overfilling protection on liquids with or without foam. ASL Works on Valcom? proprietary principle of distributed acoustic waves in a m?tal rod. If the rod is not covered by the liquid the acoustic waves are dispersed freely without any interf?rence. If liquid covers the rod the ?mission of acoustic waves is muffled and this interf?rence is picked up by the piezoelectric sensor and converted into an on-off signal.
These instruments h?ve no moving parts, no vibration, no optical or capacitive detectors. They are pure static instruments offering the maximum reliability.
