We report on a novel capacitive detection principle for Coriolis mass flow sensors which allows for three times increased sensitivity. Capacitive Coriolis mass flow sensors are normally read out by two electrodes that measure the ratio between the actuation mode and the Coriolis mode, which is induced by the mass flow. This ratio results in a phase shift between the two electrodes. By adding tw...

In recent years, the interest in integrated microfluidic systems has been steadily growing. In these systems (for instance (bio)chemical and DNA analysis and synthesis devices), accurate dosing of liquids and/or gases is of great importance. To achieve this, accurate (mass) flow sensing is necessary. This project is dedicated to the development of a new micro Coriolis flow sensor. The inherent ...

The purpose of the article is to analyze main results works that are used in calculations elevators with moderate speed modes, clarify suitability their individual positions for developing parameters centrifugal unloading high-speed elevators. Works devoted study operation elevators, which have not received a decent interpretation and development, considerable interest. As efficiency determined...

A consolidation of literature indicating the advances in the field of mass flow measurement is presently not available. Last published review paper on Coriolis mas flow meter (CFM) was in 2006. This work is an attempt is made to summarize the available works on Coriolis mass flow meter. The literature is classified into three major groups. The first group gives the summary of construction and t...

Energy equation for turbulent flow in a rotating system was derived in terms of second order correlation tensors, where the correlation tensors were functions of space coordinates, distance between two points and time. To reveal the relationship of turbulent energy between two points, one point was taken as origin of the coordinate system. Due to rotation, the Coriolis force played an important...

This article presents a model study of the dynamics icebergs and surface floats in Labrador Sea. The was forced with data on wind above ocean surface, waves, currents. These were obtained from reanalysis near-surface characteristics atmosphere for year 2008. Icebergs launched an area north coast to east Greenland generally move southeastward until they reach boundary current “highway”. After th...

Experiments and simulations from a variety of sample sizes indicated that the centrifugal force significantly affects the domain-chaos state observed in rotating Rayleigh-Bénard convection-patterns. In a large-aspect-ratio sample, we observed a hybrid state consisting of domain chaos close to the sample center, surrounded by an annulus of nearly stationary nearly radial rolls populated by occas...

Structural Integrity Meter Verification is a robust new Coriolis verification technology which uses the onboard electronics to very accurately measure the stiffness of the flowtubes. The flow tube stiffness is directly related to the flow calibration factor and is uninfluenced by process conditions. Meter Verification compares the measured stiffness to the factory baseline stiffness to confirm ...

− The weight vector theory for Coriolis flow meters has been the subject of research presented by Hemp and co-workers in various articles. The underlying theory may not be easily understood. This paper explains the application of the weight vector theory for Coriolis flowmeters. The theory is applied to simple theoretical meter configurations consisting of a single straight pipe. The applicatio...
