ETM is a robust and precise ME power meter (based on torque and revolutions measurement). It has been built on optical measurement method hence is very stable in time and does not require regular recalibration. It consists of rotating mechanical parts (measuring wheels), stationary measuring laserhead and post-processing visualisation unit installed in ECR. Additional bridge repeater can be connected via ship LAN or dedicated cable. ETM can be easily integrated with other systems, eg. ESOS.
