A seal and pivot assembly for a displacement level assembly includes a pivot base, an annular seal and a pivot body. The pivot base includes a cylindrical base member with an axial end surface defining first and second V-shaped grooves. The pivot body includes a cylindrical body member with first and second pivot body arms extending radially outward from opposite sides of the cylindrical body member. The first and second pivot body arms include first and second knife edges, respectively, that are in line contact with the first and second grooves, respectively, of the pivot base such that the pivot body can pivot relative to the pivot base, as well as uniformly distribute unbalanced forces applied to the pivot body across the entirety of the knife edges. |
