摘要：Disclosed is an arrangement for quickly measuring the phase distribution or the

component distribution in a flow cross section for substance mixtures also of a non-conducting type by measuring the complex electrical admittance. Said arrangementessentially features the following: at least one sine wave generator () which is mountedupstream from the transmitter electrodes () of the excitation level and applies analternating voltage to the transmitter electrodes (); current-to-voltage converters ()which are mounted downstream from the receiver electrodes (), amplify the alternatingcurrent that flows from at least one excitation electrode () through the medium to thereceiver electrodes (), and convert said alternating current into a voltage signal; filtergroups () and vector voltmeters () which are mounted downstream from the current-to-voltage converters () and allow the complex signal ratio U/Uto be metrologicallydetected.
