Ultrasonic flow meter – long-term stability par excellence

DDM Ultrasonic flow meters are precise flow meters for homogeneous liquids. The flow tube itself contains no moving parts and therefore the principal is featuring to be non -intrusive. It may be used for the measurement of high-purity media as well as for contaminated liquids. The fluid velocity is determined by measureing the ultrasonic transit times. This method is independent of the pressure, temperature, conductivity and viscosity of the respective fluid. Ultrasonic flow meters are characterised by minimal maintenance as well as by a long service life.
