Abstract
In apparatus for measuring the electrical resistance of a liquid employing two parallel channels for the liquid, a single induction coil is located at one of the points of connection of the channels and a single measuring coil at the other of said points of connection. In this way, parasitic electric circuits in the liquid and mutual interaction between the coils are avoided. The coils are preferably arranged coaxially above respective circular passages connecting the parallel channels.
