A magneto-inductive flowmeter for measuring the flow rate of fluids, incorporates a measuring tube, two magnetic poles externally contacting the measuring tube, and two interconnected return plates. In one embodiment, the sprocket assembly is comprised of at least three sections or segments, each of which is secured to the adjacent section or segment by a fastener, such as a tangentially-extending bolt and nut combination. In the apparatus for supplying a treatment liquid using one or more of the slit nozzles, the slit nozzles are provided in a circulating passage of a treatment liquid whose temperature is controlled. In response to identifying the metadata, a message is generated identifying the resource, the metadata, and the identified schema. A second wireless communication uplink channel corresponding to the second mobile terminal is estimated. The enclosure comprises on one of its sides at least two side closure plates, an upper plate and a lower plate, overlapping one another whereas in the upper part the enclosure comprises at least two other upper plates, one on the left and one on the right, also overlapping one another according to the width of the shaft to be covered.
