Abstract

An apparatus is disclosed for measuring the throughflow of a body liquid, in particular an apparatus for measuring the flow of urine in urological function diagnostics. The apparatus comprises a collecting funnel connected to a tube, which can be suspended in a WC bowl. In the tube are two axially spaced transducers one for continuously determining the electrical conductivity of fluid flowing through the tube from the funnel and the other for determining the specific electrical conductivity of the liquid. An electronic evaluation system determines the throughflow of the liquid upon the basis of the values determined by the transducers.
