Abstract: An apparatus and method is disclosed to monitor the condition of a fluid flow including particulate matter and air or gas content fluid in the fluid flow as well as fluid quality. The apparatus includes a sensor array with an ultrasonic transducer, inductive sensor and fluid quality sensor. It also includes a cyclonic separator. The method includes sensing and sizing particulate matter, distinguishing air bubbles from the particle matter and assessing the quality of the fluid.

Abstract: A fluid sensor assembly includes a body including a fluid passage, a first sensor connected to the body and directed toward the fluid passage, and a second sensor connected to the body and directed toward the fluid passage. At least one of the first sensor and the second sensor may be configured to transmit a signal into the fluid passage. At least one of the first sensor and the second sensor may be configured to receive at least a deflected version of the signal. The signal may include an ultrasonic pulse. The first sensor may include a focused transmitting transducer and the second sensor may include a non-focused receiving transducer. The fluid passage may include a longitudinal axis and the first sensor may be disposed at an oblique angle relative to the longitudinal axis.

Abstract: A system and method to detect particles in a fluid stream. The system includes a separator configured to separate particles from bubbles passing through the fluid stream and a sensor configured to detect the particles. The method includes passing the fluid stream through the separator, separating the particles from bubbles passing through the fluid stream, and detecting the presence of the particles.
