Abstract: PCT/US91/00400 An inductive conductivity sensor (10) is immersed in a liquid to measure its conductivity. The sensor (10) comprises a transducer (18,20,22) for generating a changing magnetic field and for inductively measuring an electric current induced in the liquid by the changing magnetic field. The transducer (18,20,22) has an external surface facing the liquid. A elastic membrane (30) separates the external surface from the liquid. The elastic membrane (30) is periodically inflated and deflated to deform its outer shape and thereby remove deposits formed on the membrane (30).
