For example, each measurement system can include a multiphase Coriolis meter and a water cut meter. Each measurement system suitably includes the capability to provide dynamic uncertainty estimates related to measurement of the multiphase flow.

Devices and methods include a Coriolis flow meter including a first and second manifolds made from a polymer material. Each manifold includes a respective tubular port extension extending outward from a surface of the manifold. A flow-sensitive tube made from the polymer material is attached at a first end to the first tubular port extension and attached at a second end to the second tubular port extension. An isolating structure is clamped around a portion of the first tubular port extension and positioned adjacent to the surface of the first manifold. The isolating structure is made from a second material different from the polymer material.

A system and method of maintaining back pressure located downstream of the flow meter maintains the pressure downstream of the flow meter in relation to the surface back pressure (SBP). At least one flow control device is located downstream of the flow meter. The flow control device (the BPV) automatically maintains the downstream pressure to less than or equal to fifty percent (50%) of the surface back pressure. A pressure regulator sets the back pressure to allow for a standalone device. Additional valves allow adjustment of the back pressure and allow for pressure relief and full flow bypass.

Monitoring a mass flowmeter includes ascertaining a resonant frequency of a bending oscillation, wanted mode, and a density measured value of a medium as a function of the frequency. A bending oscillation is excited outside of resonance with an excitation signal having an amplitude and a frequency ( times the resonant frequency of the bending oscillation, wanted mode). An amplitude of a sensor signal of the bending oscillation outside of resonance is ascertained. A value of an integrity function of the measuring tube depending on a ratio of the sensor signal amplitude to the excitation signal amplitude of the bending oscillation is ascertained. The integrity function depends further on a density term of a transfer function that models contributions of a plurality of oscillation modes to the sensor signal. This function is reduced to reference conditions, and/or transformed to an integrity value, which has no cross sensitivities for media density.
