Claim 0:
1. A measurement system for measuring an inhomogeneity of a medium in a vessel, comprising:
a first ultrasound emitter configured to send a first ultrasound signal along a first path;
a second ultrasound emitter configured to send a second ultrasound signal along a second path different from the first path;
a first ultrasound receiver configured to receive the first ultrasound signal and to measure a first measurement parameter p1 of the received first ultrasound signal;
a second ultrasound receiver configured to receive the second ultrasound signal and to measure a second measurement parameter p2 of the received second ultrasound signal; and
a control unit configured to:
receive the first measurement parameter p1 from the first ultrasound receiver,
receive the second measurement parameter p2 from the second ultrasound receiver,
determine a ratio p1/p2 of the first measurement parameter p1 to the second measurement parameter p2,
compare the ratio p1/p2 with a ratio h/D of a distance h covered by the first ultrasound signal along the first path to a distance D covered by the second ultrasound signal along the second path, and
control a process based on a comparison of the ratio p1/p2 with the ratio h/D.
