The TFI4 electronics is a sensor system consisting of differential pressure, absolute pressure, and temperature sensors. TFI4 has a processor that analysesand filters the sensor signals and processes the mass flow signal. A CAN-bus provides the connection to an engine controller (ECU) or other computing systems. The TFI4-sensor system was developed for measuring the flow of air intake to an engine, but it offers also other applications such as boost pressure measurement or a p, T-sensor combination. The individual sensors are optimized in a complex calibration process on the individual application. By this the TFI4 sensor system achieves the highest possible accuracy – exactly in the range that is required for your application. With modern coating technologies TFI4 is insensitive to a number of aggressive compounds in the fluid.
