MEASURING DEVICE AND CONDUCTIVITY METRE FOR DETERMINATION OF AMOUNT OF FLOWING CONDUCTING LIQUID, MEASURING ELEMENT AND METHOD Russian patent published in 2010 - IPC G01F23/24 G01F13/00 B01D35/143 

FIELD: measuring technology.

SUBSTANCE: invention refers to a measuring device for determination of an amount d(V(z)) of conducting liquid of the conductivity LF by a capacity with vertically (z-direction) varied filling points. There is provided conductivity metre which among others has at least two electrodes extended in a z-direction. The capacitance parametres and/or the metres are ensured so that it/they can be described by means of at least one parametric function, f_pi (V(z)) depending on V(z). At least one said parametric functions shall have exponential dependence on V(z). There is also described measuring element, and also method for determination of total amount of flowing liquid d (V).

EFFECT: simplified design of the device and method of measuring conductivity of the conducting liquid.
