Abstract
A conduit level for determination of conduit bend angles includes a frame supporting a plurality of bubble levels at various angular orientations. The frame has first and second opposite sides, a bottom edge extending along an axis, a top edge, and a front end edge connecting the bottom edge and the top edge. Each of the bubble level sensors has a unique angular orientation relative to the axis of the bottom edge of the frame. The frame includes at least one bubble viewing slot allowing a user to view the plurality of bubble levels in edgewise viewing directions facing the top edge and the front edge of the frame, and a plurality of bubble viewing windows allowing the user to view the plurality of bubble levels in a sidewise viewing direction facing at least one of the sides of the frame.
