Kiel Probes

Accurate total pressure measurement even at high flow angles

Kiel Probe Technology for Complex Flow Measurement

Widely used across a range of industries, Kiel probes are a fundamental tool for analysing flow structures. They allow accurate total pressure measurement even when the local flow is at a high angle relative to the probe axis.

While traditional Pitot tubes are generally accurate over +/ - 5°, rendering them ineffective in complex flows, the Kiel probe design incorporates an outer “ shroud ”. This aligns the flow with the internal measurement tube, ensuring accuracy even at high flow angles.

Advanced Probe Manufacturing with Direct Metal Laser Sintering

At Aero Sensor, we use the latest Direct Metal Laser Sintering (DMLS) technology to produce probes with diameters as small as 1.6mm . Available in stainless steel or Inconel, they are highly durable and heat resistant up to 980°C.

Leveraging our additive manufacturing process, we can readily integrate these probe heads into custom shapes, rakes, or complex installations. If you require a non-standard configuration, contact sales@aerosensor.tech to enquire about a bespoke solution.
