EM940 TANK RADAR MONITORING SYSTEM
Honeywell
New product
The EM940 Tank Radar Monitoring System is a marine-approved radar level gauging solution specifically developed for accurate cargo tank level measurement onboard tankers. Based on the equipment shown in the image, the unit is identified as an EM940 Radar Level Gauge, a widely used radar transmitter designed for crude oil tankers, product tankers, chemical tankers, FPSOs, and offshore storage applications.
The EM940 utilizes advanced FMCW (Frequency Modulated Continuous Wave) radar technology to provide continuous, non-contact measurement of liquid levels inside cargo tanks. Unlike traditional float-based or mechanical gauging systems, the EM940 operates without direct contact with the cargo, resulting in greater accuracy, reduced maintenance requirements, and improved operational reliability. The system is specifically designed for hydrocarbons, chemicals, bitumen, and other liquid cargoes.
Continuous and accurate cargo monitoring is critical during loading, unloading, transfer operations, and voyage monitoring. The EM940 enables operators to maintain safe cargo handling procedures while providing real-time tank level, pressure, and temperature information to central monitoring systems and cargo control rooms.
The EM940 Radar Level Gauge forms part of a complete tank gauging and cargo monitoring system. The radar is mounted on top of cargo tanks and continuously measures the distance between the antenna and the liquid surface.
Using FMCW radar technology operating at 10 GHz, the transmitter calculates ullage and liquid level with high precision. The measured information is then transmitted to the central communication interface and cargo monitoring system where volume calculations, trim corrections, heel compensation, and cargo inventory management functions are performed.
The EM940 system typically integrates with:
The radar incorporates advanced self-diagnostics, self-monitoring, and remote configuration capabilities that simplify maintenance and improve long-term reliability. The integrated inert gas pressure transmitter available on the EM940 provides additional measurement capability within a single instrument package.
The EM940 measures cargo levels without direct contact with the liquid, reducing maintenance requirements and eliminating wear associated with mechanical gauging systems.
The radar provides measurement accuracy of approximately ±3 mm instrument accuracy and ±5 mm operational accuracy, making it suitable for demanding cargo measurement applications.
The EM940 supports inert gas pressure monitoring and can transmit pressure data together with level information to the central control system.
Built-in diagnostics continuously monitor system health and provide early warning of potential faults, helping reduce downtime and maintenance costs.
Operators and service engineers can remotely configure and monitor the radar through the central monitoring system.
The EM940 is designed for installation in hazardous marine environments and complies with marine and explosion protection standards.
The radar employs a planar antenna design that minimizes product build-up and simplifies cleaning procedures.
