The data processing unit communicates with the time of flight sensor to relay real time data concerning fluid level measurements to the operator of the automobile or commercial vehicle.

An electromechanically operated lubricant dispenser having a container filled with lubricant and an electromechanical drive detachably connected to the container for conveying lubricant from the container to an outlet is diagnosed by first providing measurement data with the drive or one or several sensors integrated in the drive and/or in the container for one or more detected variables. In addition at least one condition of the lubricant dispenser is determined from the measurement data and finally the measurement data or data generated therefrom is processed as input data by an algorithm trained with methods of machine learning that classifies a condition of the lubricant dispenser on the basis of the input data.

A lubricant dispenser has at least one lubricant reservoir, an electromechanical drive which acts on at least one actuation element for discharging lubricant from the lubricant reservoir, a battery which provides a battery voltage, and a control circuit-board assembly which has at least one main circuit board having an electronic circuit assembly including at least one central microcontroller and additional electronic functional components as well as conductor tracks. The electronic circuit assembly is subdivided into a plurality of circuit islands in each of which the maximum current flowing within the circuit island in question is limited.
