Control of vortex shedding flowmeters optical fiber.

摘要

DIGITAL CONTROL SYSTEM (10) flowmeters SPILL IN WHIRLWIND OF FIBER OPTIC NEW AND IMPROVED HAS A pre-amp circuit (26) and a computer (56) to correct for temperature effects, linearity and hysteresis. SYSTEM CONTROL (10) EXCEEDS THE nonlinearity INHERENT THE PHENOMENON OF SPILL IN WHIRLPOOL AND ALSO PROVIDES A two-way communication, ACROSS THE INTERFRACES (66, 68) between the central control unit (the computer) and flowmeter OF FIBER OPTIC VORTEX SHEDDING. ENHANCED PREAMP CIRCUIT (26) INCREASES THE RANGE OF BOTTOM Flowmeter SPILL IN WHIRLWIND OF FIBER OPTIC.
