Radar Level Gauge · Cargo Level & Temperature Gauging
In cargo vessels, precise measurement and monitoring of liquid levels in tanks are crucial for safe and efficient operations. The PL3700 series is used for cargo tank instrumentation, ensuring accurate readings and reliable data transmission. This equipment is designed for marine environments and is DNV-approved, meeting stringent industry standards. Common issues include blockage of swimmer sensors by cargo residues, ultrasonic sensor fouling, temperature sensor calibration drift, and signal failure in the display or remote transmission system. Maintenance is critical, with yearly sensor calibration and swimmer inspection during tank cleaning recommended. Quarterly remote transmission tests are also necessary to ensure continuous functionality. Spare parts are available through HONEYWELL MARINE SAS, with a lead time of 3-8 weeks. It is advisable to keep seals and valve inserts on board to facilitate quick repairs.
