WATER INFLUX DETERMINING METHOD Russian patent published in 2015 - IPC G01F1/00 

FIELD: measurement equipment.

SUBSTANCE: total capacity Q(t) of pumps is measured; target volume V(t) of waste water during the required time period t is determined by calculation of integrated function Q(t) between lower integration limit t₀=0 and upper integration limit t; a variety of n pairs of values of volumes V(t_k) and the arguments corresponding to them, which are represented by time $$t_k={\displaystyle {\sum }_{i=0}^{k-1}(t_i^{\text{pumping}}+t_i^{\text{fill-up}})}+t_k^{\text{fill-up}}$$ or $$t_k={\displaystyle {\sum }_{i=0}^{k-1}(t_i^{\text{fill-up}}+t_i^{\text{pumping}})},$$ where 0<k<n, is formed; an integral chart of waste water influx is determined in the form of function W=f(t) that takes values equal to values V(t₀), V(t₁), …, V(t_k), …, V(t_n) at points t₀, t₁, …, t_k, …, t_n and I differentiates at least once, and the influx chart is determined in the form of function q(t) by finding derivative of function W(t) as to time t.

EFFECT: enlarging application scope of a water influx determining method.
