Level Measurement for Marine Methanol Service Tank (0-10 meters)
Marine Level measurement using modern radar technology increases safety and efficiency
Solutions to address customer challenges with marine level measurement
The use of methanol in the marine industry is picking up the last few years and many companies are investing in methanol propelled ships. When methanol is used for fuel, it needs to comply with the IGF code, IMO – MSC.1/Circ. 1621 Interim Guidelines for the safety of ships using methyl/ethyl alcohol as fuel and rules and regulations for the classification of ships using gases other low-flashpoint fuels.
Radar based solutions is the ideal technology. It is reliable and commonly used for large marine fuel tanks. Another strength is that only one level device is needed since the electronics can be replaced without compromising the tank integrity. In comparison, technologies that requires tank entry in case of malfunction, more devices are needed. Smaller methanol tanks require at least one continuous level measurement device and a high-high level alarm device.
