A New Generation In Cargo Tank Gauging
Radar Tank Gauging
MarRAD® is a unique and fully integrated radar tank gauging system for the monitoring of temperature, pressure, high level and overfill, and is fully compatible with loading systems.
The intrinsically safe MarRAD® offers a user friendly PC controlled display, with graphical displays showing a clear indication of all tank parameters.
Cargo Pressure & Temperature Gauging
At the heart of the system is the Deck Mount Module (DMM) which contains the highly accurate, non contact radar head, which is designed to monitor the full range of liquid products carried by modern tankers. Additional to this, the DMM has the facility to integrate tank pressure and multi-point temperature sensors for a total cargo-monitoring package.
Unique 'smart barriers' transmit the data over a single (or dual redundant) communication link to the system display and processing unit located in the control room. Twin screen options allow monitoring of both cargo and ballast tanks simultaneously, offering the ultimate convenience.

Non-contact Microwave Radar
One the few marine microwave ullage gauges featuring power and 4-20 mA signal on a two core cable, thus providing for simple, fast and cost effective installation for both new-buildings and retrofit projects. Because of its unique design and technology there is no need for large and tall adapter trunks in order to fit radar to deck.
System provides for automatic trim and list correction and allows exported level either at flotation center of the tank, at the sensor location or at the sounding pipe.
Radar Applications
Crude Oil Tanks
FPSO Tanks
Chemical / Products Cargo Tanks
LNG Tanks
Deck / Slop Tanks
Solids Cargo Tanks
Ballast, Fuel and Service Tanks
Advantages
High accuracy in all kinds of cargo.
Compact design and easy installation.
Superior technology allowing fitting close to tank side and on smaller tanks as well.
For Chemical and Oil/Products tank installations a special PTFE flange seal provides a non stick surface that eliminates cargo build-up on the radar antenna.
Measuring in solid cargoes that previously could not be done accurately with radar.

The 8" EM540 radar is especially designed to be integrated within a
dedicated cargo monitoring system for inland vessels. It may be used
for other simple tankers.
The EM540 radar is based on the use of smart sensors including
microprocessors performing signal processing. In addition to transmitting
tank level, pressure, and temperature data to the central monitoring system,
it offers such capabilities as self-diagnostics, self-monitoring and remote
configuring.
The use of an intrinsically safe two-way digital signal transmission,
between the radar and the central monitoring system, provides for an easy
integration of the EM540 Radar into any type of control system.
The EM540 radar is compliant with certification rules and regulations
issued by international classification societies.

The EM940 Radar is particularly suited for tanker sophisticated applications
such as chemicals, products, bitumen... The EM940 Radar is associated
with two specific IS racks: the TA3840C dedicated to "communication" and
the TA3840S for power supply.
The radar measurement head features a very compact design thanks to a
wide band printed circuit and a planar antenna. The use of an intrinsically
safe digital signal transmission between the radar and the central
monitoring system provides for an easy integration of the EM940 Radar
into any type of control system.
The EM940 radar is compliant with certification rules and regulations
issued by international classification societies.

AIS Radar Receiver
The Nasa Marine AIS radar is the first stand alone AIS receiver / plotter specifically designed for the leisure boat market.
The display, with ranges of 1,2,4,8,16 and 32 nautical miles shows AIS carrying vessels in a format normally associated with conventional radar. A trail of previous positions clearly chows the relative track of all the targets on the screen. A box to the right of the screen displays the speed over the ground, the vessel name, mmsi number and the latidude and longitude of any target selected by the user.
The compact unit has a white backlit LCD display, operates from 12 volts and consumes little power.
