Abstract
A system and method for measuring aeration of a liquid in a liquid channel operates by sending an ultrasonic wave into a liquid channel, receiving a signal corresponding to the echo from the liquid channel and calculating a level of aeration of the liquid in the liquid channel based on the reflected signal.
Claims19
A method for measuring aeration of a liquid, comprising:
- sending an ultrasonic wave into a liquid channel;
- receiving a signal corresponding to an echo from a liquid channel wall;
- and
- calculating a level of aeration of the liquid in the liquid channel based on the signal.
1 more element
A system for measuring aeration of a liquid in a machine, comprising:
- an ultrasonic transmitter configured to engage a liquid channel;
- an ultrasonic receiver configured to engage the liquid channel;
- wherein the ultrasonic receiver receives a reflection of an ultrasonic wave corresponding to an ultrasonic wave sent by the ultrasonic transmitter;
- and
- a controller operably connected to the ultrasonic receiver, wherein the controller is configured to calculate the aeration of the liquid channel based upon the signal from the ultrasonic receiver.
2 more elements
A machine comprising:
- a liquid pump;
- a liquid channel;
- an ultrasonic transducer proximate the liquid channel,
- a controller to calculate the level of aeration in the liquid channel based on data received from the ultrasonic transducer, including a magnitude of an echo from the liquid channel from an ultrasonic wave sent by the ultrasonic transducer.
