Tank Level Measurement Radar

Application

The SC R8 is a radar for level measurement for all types of liquids. This makes it suitable for marine tanks and land tanks containing for example:

Refined hydrocarbons, such as Diesel, Gasoline, Jet Fuel, Bitumen, and Lubricants.
Unrefined hydrocarbons, such as Crude Oil and Condensate.
A very wide range of Chemicals from IMO ship type 1 to 3.
Water and water-based substances as well as alcohols.

The SC R8 has a high dynamic range and can measure effectively on liquids with dielectric constants of 1.6. This makes the radar well-suited for Crude Oil Tankers, Product Tankers, and Chemical Tankers as well as Bitumen Tankers and Shuttle Tankers for ships transporting liquids. It is also good for marine fuel tank measurement.

The SC R8 is used on land installations on storage tanks and process tanks in many industries, from chemical industries to fuel depots.

Working principle

The SC R8 is a non-contacting radar-level transmitter. It operates on the 80 GHz band, with a half-power beam width of 3°. The device is intrinsically safe for use in a Hazardous area. It is a 2-wire device with 4-20 mA HART protocol. The software can be setup to filter away echoes from obstacles and disturbances to make accurate readings, and thanks to its high bandwidth the radar can track the liquid very close to the tank bottom and roof.

Benefits

The antenna and wetted parts of the SC R8 are designed to minimize any risk of deposits of condensation or residues. The drip-off design and the smooth surface, together with a radar with high dynamic range means no cleaning, and as there are no hidden surfaces or pockets it is the ideal choice for chemicals.

The radar handles foam, turbulence, or waves on the liquid surface. With the 80 GHz radar signal, measurements are done near the tank bottom and tank roof without problems.

With the low weight and narrow beam, it is easy to install onboard, and the 2-wire interface reduces cabling costs. It is also fully integrated with the SURVEYOR™ Cargo Monitoring System.

Accessories

An integrated service display can be installed in the radar unit, for diagnostics and changes of configuration in the radar.

It is possible to co-locate vapor pressure sensors on the same deck socket as the radar and to run cabling via the
radar using a 4-wire cable to keep costs down.
