Level Switch · Automation & Control
The L20 and L90 Level Switch series from Honeywell Marine SAS are designed to monitor liquid levels in cargo tanks through a combination of float and ultrasonic sensors. These devices are certified for marine equipment use and are compliant with DNV approvals, specifically model number TAA000013M. Common issues that may arise include blockage of the float sensor by cargo residues, ultrasonic sensor fouling, temperature sensor calibration drift, and signal failure in the display or remote transmission systems. For maintenance, it is recommended to perform sensor calibration annually and inspect the float during tank cleaning. Remote transmission tests should be conducted quarterly. Spare parts are available directly from Honeywell Marine SAS with a lead time of 3 to 8 weeks. It is advisable to keep seals and valve inserts on board for immediate use.
