Beschreibung
Zusammenfassung:	FIELD: measuring engineering. ^ SUBSTANCE: method comprises determining mass flow rate by measuring the speed of rotation of the flow and radial centrifugal pressure drop. The device comprises cylindrical housing provided with impeller mounted at the axis of the housing, inlet and outlet branch pipes arranged tangentially to the housing, and measuring unit. The housing is covered with a lid to form a passage for flowing fluid. The passage receives the blades of the impeller. The measuring unit has velocity pickup and branch pipes connected with the inlets of the differential pressure gauge and arranged radially with respect to the axis of the device. ^ EFFECT: enhanced accuracy of measurements. ^ 5 cl, 3 dwg
