Systems and methods for measuring electrical characteristic of medical fluids

A method of measuring conductivity of a fluid, the method comprising:

• receiving, through an inlet of a chamber, the fluid, wherein the fluid flows within the chamber and about multiple electrodes located in the chamber;
• applying an electrical current to first two electrodes of the multiple electrodes;
• measuring an electrical voltage between second two electrodes of the multiple electrodes;
• and
• measuring electrical conductivity of the fluid based on the applied electrical current and the measured electrical voltage,
• wherein the chamber has a surface with at least a concave portion so that bubbles within the fluid are directed away from the electrodes along the concave portion and towards the inlet or an outlet of the chamber.

A device for measuring conductivity of a fluid, the device comprising:

• a chamber that includes:
• an inlet,
• an outlet, wherein the fluid enters the chamber through the inlet and flows out of the chamber through the outlet,
• an upper surface, and
• a lower surface that runs separate from the upper surface,
• wherein the upper surface includes multiple inclined plates such that moving along a length of the chamber from the inlet to the outlet or from the outlet to the inlet, a distance between the upper surface and the lower surface changes in at least one dimension of the chamber so that bubbles in the fluid are directed from a lower distance region to a higher distance region towards the outlet or the inlet;
• and
• two electrodes configured to measure electrical voltage in the fluid that enters the chamber through the inlet and flows out of the chamber through the outlet.
