Flow sensor for toxic media and high pressures, has two tooth wheel interlock on front side, and wedge-shaped separating element is provided between interlocked faces of tooth wheel

摘要

The flow sensor has two tooth wheel (2,3) interlock on the front side. The axles of the tooth sensor lie together in an angle. A wedge-shaped separating element (4) is provided between the interlocked faces of the tooth wheel. A magnet (5) is introduced in one of the tooth wheel, which is rotated with the tooth wheel. The magnetic field of the magnet is scanned by sensors that arranged outside a housing according to the angle of rotation.
