Focus on flow measurement technology

Based on the Bernoulli effect, Vectoflow probes can be used to easily and accurately determine the pressure, speed and angle of flow of fluid flows. To do this, the pressure distribution at the probe tip is observed, which ultimately allows the flow parameters to be determined. The number of pressure holes at the probe tip determines the measurable angle range.

Kiel temperature probe

The Vectoflow Kiel temperature probes have a specially optimized inlet geometry, which also flow angles of up to 50° and the recovery temperature to within 1% can measure. Different sensor types (e.g. TCs) can be integrated and calibrated. With the help of the calibration, the recovery value can be determined, with which the measured temperature can be corrected to the total temperature.

Special multi-hole probes

With our manufacturing process, almost all probes or geometries can be manufactured. Simply send us a geometry or describe your problem and we will find a solution.
The advantage can be seen directly in the example of the lobbed nozzle. It was printed from a cobalt chrome alloy and then subjected to a surface treatment as part of the manufacturing process.
Several pressure channels and openings for thermocouples are integrated into the nozzle, which allows a lot of information about the exhaust gas flow behind a thruster to be determined simultaneously. The nozzle is an integral part of the small gas turbine, so why not install it with the instrumentation already fully equipped?
