Abstract
An apparatus and a method are provided for detecting and monitoring flow of a fluid through an injector, such as a fuel injector (10) of a diesel engine. Ultrasonic waves are detected by a transducer (12), and signals passed through a filter (20), so as to observe broadband signals of frequency above 100 kHz. Such signals are due to turbulent flow through the injector orifice (38), and so enable the flow itself to be detected.
