MEASURING SYSTEM FOR MEDIA FLOWING IN A PIPELINE

摘要

A measuring system comprises: a measuring transducer, through which medium flows, for producing oscillatory signals dependent on a viscosity of the flowing medium and/or a Reynolds number of the flowing medium; transmitter electronics for driving the measuring transducer and for evaluating oscillatory signals delivered by the measuring transducer. The measuring transducer includes: an inlet-side flow divider; an outlet-side flow divider; at least two, mutually parallel, straight, measuring tubes, connected to the flow dividers; and an electromechanical exciter mechanism for exciting and maintaining mechanical oscillations of the measuring tubes. Each of the at least two measuring tubes opens with an inlet-side measuring tube end into a flow opening and with an outlet-side. The transmitter electronics feeds electrical excitation power into the exciter mechanism while the exciter mechanism converts electrical excitation power at least partially into opposite-equal torsional oscillations of the at least two measuring tubes.
