The truckflow-insertion-probe is an ultra-fast gas mass measurement for the air management to automotive engines. It operates on the principle of differential pressure and is insensitive to deposits such as oil films or particles.

A mass measurement for gas according to the differential pressure principle typically consists of a primary element (eg orifice, venturi or nozzle), a differential pressure sensor, a pressure sensor, a temperature sensor and a computing unit that calculates the mass flow or standard volume flow. truckflow combines these five components to the smallest and fastest dp-gas mass flow meter.

The primary element is a miniature pitot tube with a patented tube profile, which is in user for thousands of demanding industrial applications (see deltaflow). In cotrast to thermal mass flow meters (HFM) superficial deposits such as oil films and particles have influence on the reading. The flow-optimized-pitot profile ensures a perfect linearity over a huge span. The pressure losses are largely negligible.

All sensors and the floe computation are on one board. The highly integratedTFI4- circuit combines dp-, p-, and T-sensors together with an ultra-fast signal analysis and data processing. Via CAN-Bus (others on request) mass flow and pressure and temperature of the fluid are available. In addition, the filtering strategy of the measured values may be adapted dynamically by the engine control unit (ECU). Comprehensive OBD messages are available.
