Abstract

The invention relates to a magnetic coupling for throughflow metering devices, in particular water meters, or similar, comprising a first and a second magnet, which are rotatably mounted and separated from each other, by a partition wall (1), which on one side (2), is surrounded by throughflowing fluid. In order to produce a simpler screening, the separating wall is made from a pressure plate (1), which comprises, on the one side (2), a first recess (4), with a first mounting (6), for the first magnet and on the other side, a second recess (5), with a second mounting (7), for the second magnet. On the side (3), not surrounded by fluid, a recess (8) is formed, which surrounds the first (4) and the second recess (5), at least in the vicinity of the magnet mountings and which serves as the mounting for a screening element (10).
