Abstract
A system is provided for the detection of deposits in a fluid line that includes, but is not limited to a measuring body, and ultrasonic transducer and an ultrasonic receiver and at least one evaluation unit connected to the ultrasonic transducer and the ultrasonic receiver. The ultrasonic transducer transmits an ultrasonic signal and the ultrasonic receiver receives response signals generated by reflections in the fluid line. From known geometric changes in shape of the fluid line, resulting response signals are finally filtered out of the response signal sequence and from the remaining response signals relating to the deposits, the distances can be calculated between the ultrasonic transducer and the deposits.
Claims18
A system for detecting deposits in a fluid line, comprising:
- a measuring body;
- an ultrasound transducer arranged on the measuring body and configured to transmit ultrasonic signals;
- an ultrasonic receiver arranged on the measuring body configured to receive a response signal in response to the ultrasonic signals transmitted by the ultrasound transducer;
- and
- an evaluation unit connected to the ultrasonic transducer and the ultrasonic receiver;
- wherein the measuring body is configured for insertion into an open end of the fluid line also configured to couple in ultrasound signals and send out ultrasonic signals in an axial direction in relation to the fluid line, and
- wherein the evaluation unit is configured to:
- store data relating to geometric changes of a shape of the fluid line;
- determine running times between transmitted ultrasonic signals and the response signal received by the ultrasonic receiver from reflections within the fluid line;
- filter out the response signal relating to the geometric changes in shape;
- and
- calculate distances between the ultrasonic transducer and the deposits from remaining response signals relating to the deposits.
