FLOWMETER USING FIBERS AND ANISOTROPIC MATERIAL FOR CONTROLLING ITS VIBRATION CHARACTERISTICS Russian patent published in 2002 - IPC

FIELD: metering mass flow of material under high pressure. SUBSTANCE: flowmeter has at least one flow pipe set in vibration by means of exciter and deformed under action of flowing material. Flow pipes have fibers oriented relative to longitudinal axis of tube over circumference, over helical line , or in parallel to this axis. Chosen sections of flow pipes may be made of composite anisotropic materials incorporating fibers. Strain gage is attached to tube surface. EFFECT: enhanced sensitivity in metering mass flow of material under high pressure. 19 cl, 20 dwg
