MetaPower is a system intended for the measurement of RPM (revolutions per minute), torque and power transferred from the main engine on a ship to the propeller(s). The system does not need strain gauges or any type of delicate electronics glued to, or mounted on the rotating shafts. The system is a digital measuring system using a laser beam for the detection of the shaft torque, the shaft RPM and consequently the transferred power. The MetaPower system offers high accuracy and good long term stability. By transmitting measured data via satellite from ship to shore, the shipping company's operation management is able to decide the most economical operating modes for the ship's engine and propulsion system. Wind turbines, mainly offshore installed turbines with controllable pitch, is another interesting market for the MetaPower system.
