Electrode-free measurement of liquid conductivity by induction, e.g. for measuring sea water conductivity, whereby a pipeline containing the liquid is shaped as a figure 8 and passes twice through an inductive ring core

摘要

Electrode-free device for measuring electrical conductivity in liquids using an inductive method has an arrangement of guiding loops in the form of closed pipelines made of non-conducting material arranged in a figure 8. The loops are fed twice through an inductive ring core. The supply and drain connections to the pipeline are made at opposite points on the figure 8.
