Objects in the tank, sharp corners, installation of the device on a large nozzle or at the centre of a dome roof, and low dielectric products (εr= 1.8...5) can cause multiple reflections. A very calm surface or a tank with a small convex or flat roof can also cause multiple reflections.If this function is in operation, the device looks for the first signal peak below the process connection. This signal peak is then used to measure the level of the tank contents.
