  • Patent number: 6568095
    Abstract: A magnetic torpedo level is adapted for removable magnetic attachment to pipes, EMT (electrical metal tubing), and other ferrometallic cylindrical objects, for measuring their level or slope. The present level includes a series of laterally placed magnets across its base edge, with a pair of ferrometallic rails capturing the magnets therebetween. Ceramic magnets are preferred for their power and longevity, but other magnets may be used as desired. The rails depend beyond the magnets, and define a channel for seating securely upon a cylindrical surface. At least one of the level vials of the present level is may be adjustably repositioned within its vial frame, in one of a series of pairs of vial passages, to adjust the angle of the vial to a specific predetermined angle relative to the level body as desired.
