DEVICE FOR CONTINUOUS DETERMINATION OF FLOW PARAMETERS OF GASSY FLUIDS Russian patent published in 2008 - IPC G01F1/86 G01F3/36 

FIELD: measuring techniques.

SUBSTANCE: measuring unit of the proposed device comprises a pipe, on which there is a first and second measuring section. The longitudinal axes of the measuring sections are oriented vertically, and their lower ends, through pipes with locking devices, are joined to inlet and outlet pipes respectively. The device also has two radioisotope apparatus for determining mass of gassy fluids, each of which comprises a USE unit for emission source and a unit for detecting UDE radiation, opposite each other, one at the upper and the other at the lower end of the corresponding measuring section. The device also comprises two radioisotope apparatus for detecting presence of gassy fluids in the cross section of the measuring sections, each of which comprises USE and UDE, in the upper parts of the corresponding measuring section on its both diametrically opposite sides. Mass flow rate of the stream during cyclic flow of fluid in the measuring unit is determined from the rate of change of mass the fluid in the filled measuring section during its discharge.

EFFECT: provision for continuous measuring process.
