Abstract
A monitoring device of an oil flow mixed with air, including a tubular element coupled with at least one first and one second photoelectric sensor that emit a radiation along a first and a second optical line respectively, the tubular element being at least partially transparent to the radiation, the first and the second photoelectric sensor being mounted on the tubular element so that the first and the second optical line are mutually angled.

An oil flow monitoring device suitable to monitor a minimal oil flow mixed with air, comprising a tubular element coupled with at least one first and one second photoelectric sensor, each of the first and the second photoelectric sensor comprising one emitter of a radiation and one receiver, the emitter directly or indirectly facing the receiver, the first and the second photoelectric sensors having a first and a second optical line respectively, the tubular element being at least partially transparent to said radiation, the first and the second photoelectric sensor being mounted on the tubular element so that the first and the second optical line are radially angled with respect to the tubular element.
Method A method for detecting the flow of air/oil inside a tubular element comprising the steps of:
- obtaining a first parameter indicative of an amount of oil present in the tubular element detected by a first sensor with a first optical line,
- obtaining a second parameter related to the amount of oil present in the tubular element detected by a second sensor with a second optical line radially angled form the first optical line with respect to the tubular element,
- determining the presence or the absence of an air/oil flow in the tubular element based on the first and/or second parameter.
