The Flexim PIOX S831 ultrasonic density and mass flow meter determines the concentration and density by means of clamp-on ultrasonic transducers mounted on the outside of the pipe. The non-intrusive technology found in this inline density meter is the system of choice when substances and processes place highest demands on safety and reliability. The sound velocity sensor PIOX S measures in real time the speed of sound through liquids. In binary liquids such as acids or sodas, the acoustic velocity is in a fixed proportion to concentration and density. PIOX S measures the sound velocity, thereby measuring the inline density and concentration of the medium.
