Abstract: A MEMS sensor for measuring at least one measured variable, especially a density, a flow and/or a viscosity, a flowing fluid, is described, comprising: at least one microfluidic channel having a channel section excitable to execute oscillations; and an exciter system for exciting a desired oscillation mode, causing the channel section to execute oscillations in a predetermined plane of oscillation. The MEMS sensor has improved oscillation characteristics at least in part because the channel section is composed of an anisotropic material, having directionally dependent elasticity and which is spatially oriented such that a modulus of elasticity determinative for a stiffness of the channel section relative to deflections of the channel section perpendicular to the plane of oscillation is greater than a modulus of elasticity determinative for a stiffness of the channel section relative to deflections of the channel section in the plane of oscillation.

Abstract: The measuring system comprises: a measuring transducer, for producing oscillatory signals dependent on a viscosity of the flowing medium and/or a Reynolds number of the flowing medium; transmitter electronics for driven 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 two measuring tubes. Each of the two measuring tubes opens with an inlet-side measuring tube end into a flow opening and with an outlet-side. The transmitter electronics feeds, by means of an electrical driver signal supplied to the exciter mechanism, electrical excitation power into the exciter mechanism, while the exciter mechanism converts electrical excitation power partially into opposite-equal torsional oscillations of the at least two measuring tubes.

Abstract: A fluid delivery system includes a flow control device and a Coriolis mass flowmeter in fluid communication with the flow control device. The Coriolis flowmeter has a flow-tube made of a high-purity plastic material, such as PFA, making the delivery system suitable for high purity applications. A controller provides a control output signal to the flow control device, which may comprise a pinch valve, so as to vary the flow control device output in response to a setpoint signal and measurement signals received from the flowmeter.
