Method for detecting bubbles in liquid, comprises light source/detector and processor which increments/decrements counter when successive measures of luminous intensity differ by more than threshold

摘要

A light source (1) has a lighting zone (4) which intersects the vision zone (5) of a light detector (2) to give a bubble detection zone (3). A processor (6) compares successive luminous intensity measurements and increments/decrements a counter according to whether a threshold is exceeded. When the counter exceeds a further threshold a warning signal to the user system is initiated An Independent claim is also included for: Equipment for detecting gas bubbles in liquid which includes light source and light detector and a control and processing unit able to compare successive luminous intensity measurements and increment/decrement a counter
