ELECTRONIC GAUGE AND METHODS OF DETERMINATION OF ONE OR SEVERAL STIFFNESS FACTORS OR MASS FACTORS Russian patent published in 2009 - IPC G01F1/84 G01F25/00 

FIELD: measuring technology.

SUBSTANCE: here is disclosed electronic gauge (20) for mass flow metres of Koryolis consisting of interface (201) for reception of vibration response and of system (203) of processing. System (203) of processing receives a vibration response, creates vibration of at least one flow metre pipe of the vibration flow metre and generates the first period τ_m1,_t1 of the pipe for the first fluid material m1, creates vibration of at least one flow metre pipe and generates the second period τ_m2,_t1 of the pipe for the second fluid material m2 and determines factor C₁ of stiffness factor or mass factor C₂ on base of the first period τ_m1,_t1 of the pipe, the first density ρ_m1,_t1, the second period τ_m2,_t1 of the pipe and the second density ρ_m2,_t1.

EFFECT: facilitating upgraded accuracy of measurement due to detection and/or quantitative representation of any changes of stiffness of measuring unit.
