Abstract
A method for detecting particles in a fluid stream includes generating a measurement field that can be passed through by the fluid stream, acquiring and evaluating measurement values of the fluid stream passing through the measurement field, and detecting at least one particle by way of a distinctive sequence of measurement values. Each of the distinctive successions of measurement values is acquired and evaluated to determine if a particle or a gas bubble is passing through the measurement field.
Claims17
A method for detecting particles in a fluid stream, comprising:
- generating a measurement field;
- passing the measuring field through the fluid stream;
- recording and evaluating measurement values in the fluid stream from the measurement field;
- detecting a particle by a characteristic sequence of the measurement values;
- recording and evaluating the characteristic sequence of the measurement values in terms of whether a particle or gas bubble is passing through the measurement field for an observation period greater than a measurement duration of a sequence of the measurement values characteristic of at least one particle or of at least one gas bubble;
- and
- determining whether a maximum of two or more extreme points have been counted once measurement values pass through the observation period.
