Functional principle
Our insertion - flow sensors operate on the
principle of thermodynamics. The measur-
ing probe is heated by several °C as against
the flow medium. When fluid moves along the
probe, the heat generated in the probe is dis-
sipated. The resulting temperature is mea-
sured and compared to the medium tempera-
ture. The flow status of every medium can be
derived from the evaluated temperature differ-
ence. Thus TURCK's wear-free flow sensors
reliably monitor the flow of gaseous and liquid
media.
