  Flowtrecs Wave is a measuring device showing the most important parameters of water, land and air vehicles equipped with petrol and diesel engines. The applications are wide and include, among others, motor boats and yachts, light planes, paragliders, motorcycles, power generators, oil burners, etc. The indicated parameters are: fuel consumption, economy of consumption, RPM speed,  speed, battery voltage and statistical parameters such as average fuel consumption, average speed etc. There are also  additional functions available, such as anchor alarm and MOB.  It comes in different configurations allowing its use for one engine, for 2 engines, for power from 20 to 500HP. It is equipped with a high brightness 4.3 glass capacitive touch screen ensuring good readability  in sunlight and reliable and durable measuring sensors made of aluminum alloys with  sapphire bearings inside. The housing is fully waterproof  IP68 which allows it to work in virtually any weather conditions.
