bf1systems pitot tubes provide accurate measurement of airspeed and flow velocity by capturing the difference between total and static pressure. This enables precise, real-time insight into aerodynamic performance across demanding applications.
Designed for reliability in high-performance environments, delivering consistent data in conditions involving vibration, temperature variation, and dynamic airflow.
From motorsport aerodynamics to aerospace and defence platforms, bf1systems pitot tubes support improved validation, system optimisation, and performance understanding through high-integrity flow measurement.
The KAP Series is designed for the measurement of dynamic air/gas pressure on or within a vehicle. When used with a Pitot Tube the transducer measures the differential air pressure which is proportional to air speed. Alternatively the KAP can be connected to pressure tappings on aero surfaces to evaluate aerodynamic performance. These transducers are suitable for use directly onto vehicles or as part of a test stand or dyno. Offering a high level of reliability and endurance, the KAP is protected against the high vibration, shock and high temperatures found in motorsport. Also suitable for wet/wet installations.
With a modular construction and programmable amplifier, this provides a fast delivery time for standard configurations. Pressure ranges are available between 25 to 75 mBar Differential. Industry standard 3-wire electrical connections allow configuration with most common ECU’s and data logging systems.
The KAP Series is race proven and can be found in many race series around the world. Please see our separate datasheet (KAPT) for details of the standard and custom Pitot Tubes that can be supplied.

A Pitot Tube is used to measure Speed relative to the surrounding air. The assembly is made up of a pair of concentric tubes; the ellipsoidal nose cone at the tip has a small aperture in the end which is connected to the inner tube whilst an annular ring of holes on the outer tube senses the static/surrounding air pressure.
Therefore by measuring the difference between the air pressure of the inner and outer tubes (please see KA Sensors KAP Differential Pressure Sensor), the speed of the vehicle can be sensed, measured and calculated.
The KAPT Pitot Tube is an in house design and is a manufactured product that is ideally partnered with the KAP Differential Pressure Sensor. Individually or used together they offer a cost effective High Performance solution for Dynamic Pressure Measurements in demanding motorsport and automotive applications; ideal for high precision data acquisition or control systems.
Offering a high level of reliability and endurance the KAPT is protected against the high vibration, shock and high temperatures found in motorsport. The KAPT is also suitable for wet/wet installations.
