The false media fill-up of chemicals during delivery and transfer from tank trucks into storage tanks can have fatal consequences.
These mix-ups lead to serious accidents again and again, especially when acids and alkalis are mixed. In order to prevent such dangerous situations, the hazardous substances committee recommends monitoring of the filling line.
FLEXIM developed the PIOX ID clamp-on ultrasonic media identification system for this purpose.
Sonic velocity – a characteristic media property
PIOX ID determines the acoustic velocity of the medium using clamp-on ultrasonic transducers mounted on the outside of the filling lines. The acoustic velocity is a substance-specific variable and constant at a given temperature. Given the acoustic velocity’s dependence on the media temperature, this is also measured by PIOX ID.
