BACKGROUND Lubrication systems can be used in various contexts where mechanical parts of an object need to be lubricated. An example of such an object is an engine of a vehicle. When operating a single-engine engine, this must be provided with lubricant in order to be able to function as intended. Said lubricant may, for example, be some type of oil. A sensor system can also be used to lubricate other components of a vehicle, for example auxiliary unit or a differential unit. called rnomerite distributor. in a tvp of the siriorjsvstern nos vehicle a pehäiiare is included which reaches the said lubrication line. The lubrication system also includes a pump arranged to pump up the lubrication line from the container via a line and at a pressure side thereof convey the said lubrication motor to the vehicle. The applied torque can in this case act as a torque in said motor, whereby friction with said mechanical parts in the rotor can be reduced. In this case, the performance of the motor may be reduced to one degree. Siriorjrnedei which tiiiförts said rnotor'kan hereby, via a therefore intended iedriing, iedas tiiibaka tiii said benåiiare, öterförarideav srnörjniedei tiii said behäiiare can be done rnedeist gravitatiorisverkarr eiier rrtedenat therefore 'intended intended. Said lubrication valve can in this case be a sutured system.

In order to ensure that the required amount of srnörjrrtedei is present in the lubrication system, of which one is present in said container, a level sensor is provided in the beifåiiareif. When the vehicle and thus the lubrication system are in a state of operation and at the same time, according to the prior art, a meshing of the level of lubrication in the heater is performed. Typically, a prevailing amount of torque is detected in the lubrication system at a tipping start of the vehicle, when the vehicle can be assumed to be stationary and cracks for said detection are favorable, for example when driving the engine of said engine.

If the lubricant level is below a certain dry matter value, this can be taken as an indication that lubricant needs to be doubled in the lubricant. If the lubricant level falls below a certain dry matter value, this can alternatively be taken as an indication that leakage of the lubricating valve is dry rigging.

If the lubricant level exceeds a certain toruthent value, this can be taken as an indication that a dilution of lubricant has taken place and the lubrication system must be examined further. Said dilution may have different artiedningarr.

The expression "take as an indication" may imply that "taststaiia indication".

It is of the utmost importance that the amount of lubricant in the tortoise opening exceeds a certain level because a liquid level can cause damage to said objects which are lubricated by the lubricating agent. It is also of the utmost importance to detect the eventual dilution of lubricant in the lubricating fluid as this may also cause damage to said objects or to adversely affect the same in some respects, except in the prior art, a prior art may in a relatively long period of time. srnörjrriedei hos smörjsvsternet hos fordon, This may be a consequence of the fact that in the aiirnärinet there is aiittör 'ogvnrisarnnia dritthetingeiser undertrarndrrivrting of the said vehicle so that adequate rnätningar' of sniörjrriedeiriivfa can be performed here. This may imply that in the case of a detection of the level of lubrication medium, where the level is below a certain predetermined reference value, the next level may not have fallen below the predetermined reference value. In this case, damage to the said object may have been caused. in the worst case, said object may be damaged. Similarly, this may mean that a level of lubricant in the heater has long since exceeded a certain predetermined reference value. In this case, damage to said objects can be caused, in the worst case, said objects can also in this case be affected by a naveri.

It is thus desirable to be able to effectively ensure that a lubrication device mentioned above is within a certain lengthy interview in order to avoid damage to an object which is to be damaged by said lubrication system, the damage being caused by, for example, external damage.
