    Abstract

    The design and construction of a new automatic volume change unit, which is capable of measuring large volume changes without the need for reversing flow direction, is described. It works on the principle of a floating magnet at an air-water interface activating a magnetorestrictive sensor. Its performance is assessed against the criteria listed by Lade (1988) as desirable for any automatic volume change measuring device, and is shown to satisfy these criteria.
