The Flexim PIOX S831 liquid analyzer is certified for operation in hazardous areas (ATEX/IECEx zone 1, FM Class I Division 1+2). It determines concentration and density of liquids by means of clamp-on ultrasonic transducers mounted on the outside of the pipe. Non-intrusive technology is the system of choice when substances and processes place highest demands on safety and reliability. The PIOX S dynamically infers the fluid’s density using its sound speed and temperature. For binary liquids such as acids or sodas, the acoustic velocity is in a fixed proportion to the concentration and density. The meter also has the ability to measure the volumetric flow using the transit time difference method. It can therefore provide mass flow in liquids of varying quality.
