Abstract
Systems and methods are disclosed for differential pressure meters having a constant beta edge boundary defined by fluid displacement members of the meter. In some embodiments, a differential pressure meter may have an interchangeable fluid displacement member, such that each fluid displacement member replaced in the meter maintains a constant beta edge boundary. In other embodiments, a family of differential pressure meters having permanent fluid displacement members may maintain a constant beta edge boundary for each meter of the family of differential pressure meters.
