Effective flow measurement
Althen offers a comprehensive programme of flow meters. These allow you to measure the velocities of the associated vectors with high precision, specialising in the aviation, automotive, wind turbine and wind tunnel testing industries.
Dynamic pressure probes
We supply dynamic pressure probes from Aeroprobe, one of the leading manufacturers of Pitot and Prandtl probes. Aeroprobe products allow you to measure air and flow data with high precision - and in real time. This makes your operation more efficient and improves your technology. Our portfolio of pitot tubes covers standard applications as well as unusual and complex test scenarios, for example for extreme temperatures - high and low.
How dynamic pressure probes work
Dynamic pressure probes are instruments used to measure the dynamic pressure created when a fluid (e.g. air or water) flows against a surface. These probes are based on the principle of dynamic pressure, which states that the pressure of a fluid increases as it flows through a constriction and that this pressure is proportional to the velocity of the fluid.A typical pitot tube consists of a conical probe or pipe that is open at one end and connected to a manometer or pressure sensor. The probe is designed to capture the back pressure of the fluid as it flows against the tip of the probe. When the fluid flows against the tip of the probe, the dynamic pressure is generated, which is proportional to the velocity of the fluid. This pressure is measured by a pressure sensor or manometer connected to the probe. The velocity of the fluid can be calculated by measuring the dynamic pressure. This conversion is carried out using a suitable calibration that indicates the relationship between the measured pressure and the velocity of the fluid.
Calibration and accuracy of pitot tubes
The accuracy of pitot tubes depends on a number of factors, including the accuracy of the pressure sensor or manometer, the calibration of the tube, the flow conditions and the ambient temperature. Careful calibration and verification are important to ensure accurate measurement results.Overall, pitot tubes are important instruments for measuring flow velocities in various applications and play an important role in collecting and analysing flow data.

Micro Air Data Computer
Aeroprobe's innovative flight system solutions are designed to meet the unique requirements of unmanned aerial vehicles (UAVs) and other autonomous platforms and include multifunction air data probes and micro air data computers. These state-of-the-art products are designed to provide critical data for safe and efficient flight operations.
The multifunction air data probes are at the forefront of technology and offer a wide range of functions, from airspeed and angle of attack measurements to altitude and temperature measurements. They ensure precise and reliable data acquisition for aircraft systems, contributing to improved performance and safety.
Complementing our pitot tubes, Micro Air Data Computers are compact and sophisticated, processing critical flight data with exceptional accuracy. They enable real-time data analyses and mission-critical decision-making. Minimised weight, size and power requirements ensure that our solutions are efficient and optimised for the requirements of UAVs and autonomous platforms.
Pressure and temperature measurement systems from Althen put to the test
Air flow measurement in an electric private aeroplane: The Silverwing electric aeroplane from TU-Delft has a flow sensor consisting of a 5-hole pitot tube and an on-board measuring unit. Flow parameters such as airspeed, angle of attack and side-slip angle ensure that the aircraft can fly stably and efficiently.
Pressure sensors for the Delft Hyperloop braking system: In 2019, the Dutch Delft Hyperloop student team will once again take part in the competition for the SpaceX Hyperloop Pod. Pressure sensors from Althen provide the team with real-time information about the pressure in the braking system.
