Differential pressure gas mass flow sensor for OEM
systec Controls
TFI4 includes p-, dp- and T-Sensors and an ultrafast signal prozessor. By its digital communication (CAN Bus, others on request), TFI4 is able to transmit not only the precise mass flow of any gas, but is also sending Temperature and pressure and a number of diagnostic data. Furthermore, TFI4 can be adapted on applications by bus, e.g. intelligent damping strategies or automized zero offset compensation may be performed for challanging application.
Typical applications are: Air- and EGR-mesurement on engines, stack-gas measurement, pressurized air, HVAC, pneumatic automization and many more.
