Abstract
A system and method for detecting a flow rate using ultrasound is disclosed. A flow rate detector includes a disposable conduit section and a reusable sensor chassis, the chassis configured to fit over an outer surface of the conduit section, the chassis configured to attach along a length of the of the disposable conduit section, and including first and second transducers configured to, when the reusable chassis is attached to the conduit section, measure a flow rate of a fluid passing through the conduit section by measuring an ultrasonic transmission between the first and second transducers through the fluid. The ultrasonic transmission is reflected at least once off of the inner surface of the disposable conduit before being received at the second transducer.
