A novel neural-network based technique is described for the remote condition-monitoring of an in-service gas-turbine flowmeter. The method uses a C language implementation of a modified multi-layer perceptron (MLP) neural networks, which enables detection of the accumulation of contaminating material on the rotor blades that could lead to changes in meter-factor and loss of calibration.

The dynamic response characteristics of flowmeters are often incompletely or incorrectly specified. This is often the result of inadequate dynamic testing. This paper describes a robust method for determining the dynamic response characteristics of flowmeters. The results of frequency response tests on a number of flowmeter technologies are presented. A concise way of specifying the dynamic per...

Abstract. This paper reports on the methodology developed for a new hydraulic interpretation of flowmeter logs, allowing better characterization continental hydrological basins. In course log, different flow stretches are established, mostly corresponding to permeable layers (aquifers), among which there other mainly less (aquitards). such basins sufficient thickness, these may not have same he...

The phenomenon of linear motion conductor in a magnetic field is commonly found electric machineries such as, electromagnetic brakes, induction motor, flowmeter etc. design and analysis the same requires an accurate evaluation induced currents associated reaction fields. finite element method generally employed numerical technique for this purpose. However, it needs stabilization techniques to ...

background & objectives: ischemic stroke is the third leading cause of death and disability in most of the human societies. there is no effective treatment due to complexity of the pathophysiological mechanisms. today, more researches are designed to introduce involving factors and new treatment strategies in brain ischemia. the objective of this study is to introduce an experimental model of t...

Abstract Coriolis mass flowmeters are resonant meters. In this paper, the intrinsic mode of CMF300 model flowmeter under fluid-structure interaction is calculated numerically, and excitation force in working state analyzed. According to results modal analysis, harmonic response analysis was carried out, displacement, stress, strain curves action different frequency loads were obtained. It provi...

The existing viscous and incompressible theory of isothermal sound propagation attenuation in suspensions considers solid particles which are infinitely viscous. We extend the by applying amended Coriolis flowmeter “bubble theory”. Here, drag force is a function both fluid particle Stokes numbers particle-to-fluid ratio dynamic viscosity (Galindo Gerbeth, 1993). Aerosol hydrosol examples presen...
