Abstract
A conduit sensor device comprises a first end portion, a second end portion, a first magnet rotor assembly residing proximate the first end portion of the device and rotatable between first and second positions, a second magnet rotor assembly residing proximate the second end portion of the device and rotatable between first and second positions. The first magnet rotor assembly includes a first plurality of magnets axially arranged about a first axis. The first magnet rotor assembly includes a first top portion and a first bottom portion securing the first plurality of magnets within the first magnet rotor assembly. The second magnet rotor assembly includes a second plurality of magnets axially arranged about a second axis. The second magnet rotor assembly includes a second top portion and a second bottom portion securing the second plurality of magnets within the second magnet rotor assembly.
