Abstract
A flowmeter for a multi-phase medium includes an ultrasonic transducer, a permittivity sensor, and a controller. The ultrasonic transducer converts electrical transmitting signals into ultrasonic transmitting signals, radiates them into the measurement volume, receives reflected ultrasonic receiving signals from the measurement volume, and converts the ultrasonic receiving signals into electrical receiving signals. The controller determines a reflection energy of the ultrasonic receiving signals from the measurement volume using the electrical receiving signals and distinguishes between, on the one hand, the water and the oil and, on the other hand, the gas in the measurement volume using the reflection energy. The controller determines a permittivity of the medium in the measurement volume using the permittivity sensor and distinguishes between, on the one hand, the water and, on the other hand, the oil and the gas in the measurement volume using the permittivity.
