Abstract
A fluid quality sensor for measuring a quality of a fluid comprises a measurement section mounted to an output side of a pump for the fluid.
Claims16
A fluid quality sensor for measuring a quality of a fluid, comprising:
- a measurement section mounted to an output side of a pump for the fluid, the measurement section is at least partially located in a fluid cavity of the pump;
- an ultrasound or infrared source emitting an ultrasonic or infrared signal into the measurement section;
- an ultrasound or infrared detector receiving the ultrasonic or infrared signal after passing through the measurement section;
- and
- a reflector structure for the ultrasonic or infrared signal.
