ABSTRACT:
In one embodiment, an ultrasonic flow meter is provided for measuring a flow rate of a medium flowing through a conduit, the ultrasonic flow meter comprising two ultrasonic emitters and two ultrasonic receivers mounted to the conduit. The flow rate is determined based on a first time interval of a first ultrasonic signal traveling from the first ultrasonic emitter to the first ultrasonic receiver, and a second time interval of a second ultrasonic signal traveling from the second ultrasonic emitter to the second ultrasonic receiver. In some embodiments, the first and second ultrasonic signals travel in a downstream direction with respect to the flow. In other embodiments, the first ultrasonic signal travels along a first transmission path that forms a first angle between the first transmission path and the flow direction, while the second ultrasonic signal travels along a second transmission path that forms a second and different angle between the second transmission path and the flow direction.
