Functional principle

Our insertion - flow sensors operate on the

principle of thermodynamics. The measuring

probe is heated by several °C as against

the flow medium. When fluid moves along

the probe, the heat generated in the probe

is dissipated. The resulting temperature is

measured and compared to the medium

temperature. The flow status of every

medium can be derived from the evaluated

temperature difference. Thus TURCK's wearfree flow sensors reliably monitor the flow of

gaseous and liquid media.
