Precision Data collection■
The VAF SPU3 is engineered to deliver clarity in complex marine operations. Designed for integration with flowmeters, torque sensors, GPS, speed log and additional (existing) sensors, the SPU3 consolidates data into a single Ethernet output. This enables real-time insight via the PEM4 touchscreen (on board) and IVY cloud platform (in office). Whether installed near consumers, booster units or in the engine control room, the SPU3 ensures reliable performance in demanding environments. With support for up to 12 flowmeters and multiple signal inputs, it empowers operators to monitor fuel efficiency of consumers, ships’ propulsion efficiency, and environmental data with precision, The result: smarter decisions, lower emissions, and optimized ships’ efficiency.

Why choose VAF SPU3
The VAF SPU3 is a high-performance Data collection Unit designed to bring structure and insight to complex marine propulsion data. Built for integration with flowmeters, torque sensors, GPS, speed log, and auxiliary systems, the SPU3 consolidates all inputs into a single Ethernet output, ready for visualization on the PEM4 touchscreen or remote access via the IVY cloud platform.
Its modular architecture supports up to 12 flowmeters and 9 analog inputs, making it suitable for both single and twin-screw vessels. The SPU3 enables precise monitoring of fuel consumption, shaft power, thrust, and efficiency metrics such as SFOC (g/kWh) and EEOI(kg CO2/ton NM). It also supports temperature compensation, density calculations, and draft/inclino measurements.
Installation is straightforward, with DIN-rail mounting and clear IO labeling. Built to IP65 standards, the SPU3 performs reliably in demanding engine room environments. Whether you’re optimizing fuel usage or preparing for emissions reporting, the SPU3 delivers the data you need, when and where you need it.
