Abstract: A measurement system for measuring an inhomogeneity of a medium in a vessel includes: a first ultrasound emitter for sending a first ultrasound signal along a first path; a second ultrasound emitter for sending a second ultrasound signal along a second path different from the first path; a first ultrasound receiver for receiving the first ultrasound signal and measuring a first measurement parameter p1 of the received first ultrasound signal; a second ultrasound receiver for receiving the second ultrasound signal and measuring a second measurement parameter p2 of the received second ultrasound signal; and a control unit: receives the first measurement parameter p1 from the first ultrasound receiver, receives the second measurement parameter p2 from the second ultrasound receiver, and determines a ratio p1/p2 of the first measurement parameter p1 to the second measurement parameter p2.
