Abstract
Disclosed is an apparatus for determining flow parameters of a particle-fluid flow. Said apparatus comprises a first sensor array (SA1) that reacts to particles and has an equidistant division within planes extending vertical/at an angle to the direction of flow (z) in accordance with the position of the particle path, and an evaluation unit (4) to which the sensor unit signals (e) of the sensor unit are fed that can be attributed to passing particles and which is designed to determine a particle velocity on the basis of said signals. In addition to the first sensor array (SA1), a second sensor array (SA2; SA2'; SA2") is provided which has a different division within planes extending vertical/at an angle to the direction of flow in accordance with the position of the particle path, and the signals of which are likewise fed to the evaluation unit (4). The evaluation unit (4) is designed to determine a particle velocity as a function of the location on planes extending perpendicular to the direction of flow from the signals that both arrays feed to the evaluation unit (4).
