2. Challenges in Marine Flow Measurement
Marine applications are extremely challenging due to:
- High salinity and corrosion
Saltwater damages standard flow meters.
- Continuous vibration
Ships and offshore platforms cause mechanical stress.
- Temperature fluctuations
Engine rooms can exceed 50°C while seawater is cold.
- Fuel with varying viscosity
Diesel, bunker fuel, marine gas oil (MGO) require different meter types.
- Biofouling
Marine organisms can clog sensors.
- Limited maintenance accessibility
Equipment must be highly reliable.
- Strict environmental regulations
Ballast water discharge must meet IMO standards.
Saitechflow meters are engineered with special materials and coatings to withstand these demanding conditions.
