Product Overview
Reliable radar tank gauging for marine operations
Accurate tank level measurement is essential during loading, discharge and day-to-day vessel operations. The Honeywell EM540 and EM940 Marine Radar Level Gauges provide continuous, non-contact level measurement for cargo tanks, helping operators monitor liquid levels without relying on mechanical measuring components inside the tank.
Using FMCW radar technology, the gauge measures the distance between the antenna and the liquid surface and converts this into precise ullage and tank level data. This makes the solution particularly suitable for demanding marine environments where reliable cargo monitoring is critical.
The EM540 and EM940 can form part of a wider marine tank gauging system, combining tank level information with pressure, temperature, ballast and vessel monitoring data. Measurement information can be transferred to the cargo control room and integrated with shipboard monitoring and control systems.
Designed for demanding tanker applications
The radar gauges are suitable for applications such as:
- Chemical tankers
- Product and cargo tankers
- Bitumen carriers
- FSO and FPSO vessels
- Inland tankers
- Cargo and ballast tank monitoring
Why choose radar level measurement?
Because the measurement is non-contact, the radar gauge does not depend on a mechanical float moving inside the tank. This can help reduce problems associated with product build-up, wear and mechanical obstruction while maintaining continuous tank level information.
The EM540 also supports self-monitoring, diagnostics and remote configuration, helping simplify operation and maintenance within an integrated marine tank gauging system.
