The invention relates to a flow monitor for monitoring the flow of flowing media, wherein a paddle projecting into the flow transfers the rotating movement of the paddle onto a display device by means of a magnetic gear comprising a plurality of individual magnets corresponding with each other.

Paddle-type flowmeter with magnetic coupling

The invention relates to a method for controlling a heatable dehumidifier. The heating of the dehumidifier is to be actuated only when several congruent time windows within which a temperature gradient is greater than or equal to 0 could be determined during a certain period of time, i.e. the heating is to be actuated only when no air flows into the interior of the expansion vessel of the transformer.

Method of drying an air dehumidifier

The invention relates to a method for dehumidifying air and to an air dehumidifier. To this end, a filter element is provided that is filled with granular material that can be regenerated by baking out. For effecting this baking out, a heating device is provided that is only actuated when both a humidity sensor indicates that a humidity limit value has been exceeded as well as a relative pressure sensor or a comparable technical means indicates that, at the moment, no flow toward the oil expansion tank is recorded.

An electric power apparatus has a oil-filled vessel in which a float is connected to a float shaft that rotates as the float rises and falls with the level of oil. A level indicator has a display shaft extending along and pivotal about an axis, and coupled to the float shaft. An indicia display adjacent the shaft is swept by a pointer fixed on the shaft and juxtaposed with the indicia display go that the level of the oil in the vessel is indicated by the pointer. A disk fixed to the shaft has an outer periphery with a region of a shape having a radius varying angularly from one end of the region to an opposite end of the region. A noncontact proximity sensor is radially spacedly juxtaposed with the region of the disk for producing an output corresponding to the radial distance between the region and the sensor.
