Abstract

A fill level measurement device is provided, including a first radar chip and a second radar chip that is synchronised with the first radar chip, the first and second chips each include one or more transmission channels, each configured to radiate a transmission signal, and one or more reception channels, each configured to receive a reflected transmission signal from a filling material surface; an evaluation circuit, connected to the first and second chips by a data line assembly and being configured to calculate a fill level and/or a topology of the filling material surface of a medium in a container from reflected transmission signals received from the first and second chips; and a clock line assembly that connects the first chip to the circuit and is configured to provide the circuit with a common clock signal for evaluating the reflected transmission signals received from the first and second chips.
