TURBINE CONSUMPTION CONVERTER Russian patent published in 2019 - IPC G01F1/10 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the measuring equipment and can be used during the liquids and gases flow rate and amount measuring by means of the large and small diameters flow meters. Turbine flow rate transducer includes housing with the through flow channel, in which two fairings are located along the channel axis, between which a sensitive element is mounted with possibility of rotation and on the housing outer side a signal pickup unit is installed. According to the technical solution, the sensitive element is made in the form of at least two rigidly and coaxially interconnected small turbines with blades are successively installed, at that, the blades side surfaces of the first, in the flow in the flow meter direction, small turbine from the incident flow side are made with bevels, which surfaces form the confuser input into the small turbine inter-blade space, and the blades lateral surfaces of the latter, in the flow in the flow meter direction, small turbine on the side opposite to the incident flow are made with bevels, of which surfaces form the diffuser output from the small turbine inter-blade space.

EFFECT: achieved when using the claimed invention technical result is the measurement range expansion as a result of increase in the small turbine sensitivity at low flow rates and the small turbine design simplification.
