Abstract: The present application relates to a lubrication system (S) comprising dosing means (1-1) for feeding lubricant to a lubrication point. The invention is based on the idea that computerized control means (1-5, 1-6) are arranged to control the operation of the lubrication system (S). The dosing means (1-1) are configured to operate responsive to a control signal provided by the control means (1-5, 1-6) to adjust the amount of lubricant to be fed by the dosing means (1-1, 1-2) to a lubrication point as required by the control means, wherein the amount of lubricant can be adjusted lubrication-point-specifically.

Abstract: The invention relates to an arrangement in connection with a central lubrication system. The arrangement includes a lubricant vessel, a pump unit, a control unit, pipe systems, a pressure monitor unit, at least one lubricant feeder provided with at least one piston which moves due to the influence of the pressure of a lubricant present in the pipe system/object to be lubricated, and a movement monitor unit to monitor the operation of the feeder. The movement monitor unit includes a sensor part mounted to a nipple manufactured from a weakly magnetable material. The nipple includes a permanent magnet to generate a magnetic field, and a sensor for detecting movement of the piston, and an electronics part which processes a signal received from the sensor and forwards this processed signal to the control unit.

Abstract: The invention relates to an oval gear meter for flow measurement, the meter comprising: two oval-shaped gears (1, 2) arranged to rotate in synchronism in a chamber provided in a housing (3), through which chamber a medium to be measured is arranged to flow, the rotating motion of the gears (1, 2) being pro-portional to the flow rate. The meter is equipped with means for detecting the rotating motion of the oval gears (1, 2). The means for detecting the rotating motion of the oval gears (1, 2) comprise a permanent magnet (8) arranged to one of the oval gears (1 or 2), centrically with the rotating shaft (7) thereof, and a sensor circuit (9) arranged on the outer surface of the housing (3) wall, at a location coinciding with that of the permanent magnet (8).
