ROTAMETERs™ (Variable Area Meters) are named after ROTA, one of the European inventors of this flow principle in the beginning of the century. ROTA invented the rotating float, which is self-guiding and has less friction in the pipe so that a more precise measurement is possible. Rota Yokogawa is one of the main suppliers of ROTAMETERs™ in Europe.
