SMTS Marine Solutions LLC supplies, supports, and provides technical services for the Honeywell EM540 and EM940 Radar Level Gauges, advanced fixed tank gauging systems designed for continuous, high-precision level measurement on marine vessels. Engineered with FMCW (Frequency Modulated Continuous Wave) radar technology, these marine-approved radar gauges deliver accurate, reliable, and maintenance-friendly cargo tank monitoring without making contact with the liquid surface.
Designed for oil tankers, chemical carriers, bitumen tankers, FPSOs, FSOs, and inland river vessels, the EM540 and EM940 integrate level, temperature, pressure, and ballast monitoring into one intelligent system, ensuring safe cargo handling and regulatory compliance.
SMTS Marine Solutions LLC – EM540 & EM940 Marine Radar Level Gauges | Advanced Fixed Cargo Tank Gauging Solutions
Why Choose the EM540 & EM940 Radar Level Gauges?
Modern cargo operations demand continuous, accurate tank level monitoring to ensure safe loading, unloading, and cargo management. The EM540 and EM940 provide dependable non-contact measurement that eliminates wear associated with mechanical gauging systems while minimizing maintenance requirements.
Key Features
- Advanced FMCW radar technology for highly accurate non-contact level measurement
- Continuous cargo tank level monitoring
- Integrated temperature, pressure, and ballast monitoring
- Smart sensor technology with embedded digital signal processing
- Self-diagnostics and continuous health monitoring
- Remote configuration capability
- Intrinsically Safe digital communication
- Compact and robust stainless-steel construction
- Flat planar antenna minimizes product build-up
- Easy cleaning and reduced maintenance
- High accuracy even in demanding marine environments
- Fully compliant with international marine classification requirements
How the Radar Gauging System Works
The EM540 and EM940 determine the distance between the antenna and the liquid surface using Frequency Modulated Continuous Wave (FMCW) radar technology. The radar signal is reflected from the cargo surface and processed by an embedded Digital Signal Processor (DSP), which calculates the tank ullage with millimeter-level precision.
Measured data is transmitted digitally to the vessel’s Cargo Control Room together with:
- Tank level
- Temperature
- Pressure
- Ballast information
The system interfaces seamlessly with:
- Marine Cargo Control Systems
- Integrated Control & Monitoring Systems (ICMS)
- Ship Loading Computers
- Honeywell Marine CIU
- Intrinsically Safe TA3840S power supply racks

Since the radar never contacts the cargo, there are no moving parts exposed to the product, significantly reducing maintenance and mechanical failures.
Improved Operational Safety
Continuous real-time monitoring helps maintain vessel stability during loading and discharge while reducing manual tank measurements.
Reduced Downtime
The proprietary flat antenna minimizes cargo deposits, allowing quick cleaning and uninterrupted operations.
Smart Diagnostics
Built-in self-monitoring continuously checks system health, enabling predictive maintenance and reducing unexpected failures.
Marine Certified Design
Designed specifically for marine cargo tanks and compliant with international classification society requirements.
