Flow Sensor, Method and Flowmeter for Determining Speeds of Phases of a Multi-Phase Medium

A flow sensor for a flowmeter, wherein the flowmeter is designed for determining speeds of phases of a multi-phase medium, the flow sensor comprising:

• a sensor carrier having at least one first sensor array;
• the at least one first sensor array has a first permittivity sensor for determining a first permittivity of a multi-phase medium, a second permittivity sensor for determining a second permittivity of the medium, a density sensor for determining a density of the medium, and a first sensor axis;
• the first permittivity sensor, the second permittivity sensor, and the density sensor are arranged on the sensor carrier along the first sensor axis;
• and
• the first permittivity sensor and the second permittivity sensor are spaced apart with a permittivity sensor distance.
