JET-TYPE FLOWMETER Russian patent published in 1999 - IPC

FIELD: measurement and control of flowing media flows. SUBSTANCE: flowmeter has nozzle coupled to inlet channel, drain cavities coupled to outlet channel, wedge-type splitter positioned opposite to nozzle and provided with hollow facing the nozzle, and working chamber. Splitter hollow is made as channel closed at line end, and axis of this channel is shifted relative to nozzle axis. Value of shift does not exceed half the value of difference between width of channel open end and nozzle width, and width of channel open end exceeds nozzle width. Due to these peculiarities flowmeter has low sensitivity threshold and allows measurement of low flow rates of gas and liquid. EFFECT: enhanced accuracy.
