METHOD OF MEASUREMENT OF LEVEL OF LIQUID Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: resistance R₁ is measured in circuit between submerged electrodes, depth of submersion of electrodes is changed by Δ, resistance R₂ in circuit between submerged electrodes after change of depth of their submersion is measured and level of liquid is determined, Description gives mathematical expressions to calculate level of liquid. EFFECT: enhanced accuracy of method. 7 dwg
