Description of the pitot tube

Our FloTec pitot tubes are used for measuring flow according to the differential pressure principle. The volumetric flow is calculated from the difference between the static pressure and the dynamic pressure using Bernoulli’s principle and taking into account the pipe inner diameter. Using four dynamic ports this instrument is able to evaluate a better profile for the velocity inside the pipe. This ensures a higher accuracy in the measurement.

The upstream side is designed to generate a break point, due to which the medium passes around the pitot tube without causing any turbulence. This feature creates a stable pressure with a constant flow coefficient at the downstream measuring point, even at high flow rates. Thus a very wide range of applications in the field of flow measurement is enabled.
