The Simulation of Coriolis Meter Response to Pulsating Flow Using a General Purpose F.E. Code

The effect of flow conditions on the sensitivity of the Coriolis flowmeter

“…Significant progress was made by investigating the effect of flow pulsations (e.g. [3][4][5]), but otherwise there have been relatively few systematic studies dealing with the effects of non-ideal inlet-flow conditions (known as installation effects) on Coriolis flowmeters. In [5] an experimental study of the flow disturbances introduced at the inlet of some commercial Coriolis flowmeters was presented.…”

The performance characteristics of a micro-machined Coriolis flow meter: An evaluation by simulation

“…Ref. [8] describes such a model, which was developed from the 2-D model described in [9], modified by the inclusion of the effects of axial tension and torsion. Details of the appropriate mass, stiffness and 'damping' matrices are given in both [8], for (3-D) and [9], for (2-D).…”

“…The present modelling work was developed from the approach described in [8]. When this FE model is applied to a simple, straight fluid-conveying pipe, the meter can be discretised as Timoshenko beam elements (which include the effects of shear deformation) with two nodes.…”

Coriolis mass flow rate meters for low flows

“…-TR 11.0 Processing precision: From PoP tests, it is seen that the processing precision of 24 bits 18 , and the high dynamic range due to an 8-bit exponent, offered by the IEEE 754 32-bit floating point representation is sufficient to carry out trigonometric calculations and implement IIR digital filters for phasedetection. As such, a typical 32-bit signal-processor (with a 32 bit FPU) is recommended.…”

“…As the repeatability applies to the totalizer at full flow, it is tested at 100 g/h for a period of 1 hour. 18 IEEE 754, Single-precision 32-bit representation: 23 bit fraction + 1 implicit bit 19 MIL-STD-961E TM 3.0 Temperature Ambient temperature testing requires a temperature-controlled environment. A programmable environment chamber shall be used to create predefined temperature ramp for dynamic temperature tests.…”
