Precise fluid flow control is one of the most important aspects of many chemical processing systems, both reactive and analytical. Recent research has led to a sensor capable of very precisely measuring mass flows up to 1g/h, based on the Coriolis principle. However, applying such a measurement in a flow control system is not yet possible, as valves capable of regulating such small flows do not...

This research article highlights Omega type Coriolis Mass Flow Sensor (CMFS) used for measuring direct mass flow. CMFS works on the principle of Coriolis effect. In this research article omegatype, CMFS has been investigated for evaluatingresonant frequency. Modelling of CMFS can be split into two domainsstructural and fluid. The omega shaped tube, forming the structural part and the fluid flow...

We have designed, fabricated and tested a micromachined Coriolis flow sensor for the measurement of hydrazine (N2H4) propellant flow in a micro chemical propulsion system (μCPS). The sensor will be used for measurement and characterization of the μCPS in a simulated space vacuum environment. To reach the required flow range a bypass system is integrated. Initial measurements demonstrate an incr...

We present analytical results allowing to understand the influence of usually neglected vertical component of the Coriolis force and of the vertical velocity contribution in its horizontal component upon wave-trapping in shear flows in stratified fluid, and upon related inertial instability.

One of the challenging problems in the Oil & Gas industry is accurate and reliable multiphase flow rate measurement in a three-phase flow. Application of methods with minimized uncertainty is required in the industry. Previous developed correlations for two-phase flow are complex and not capable of three-phase flow. Hence phase behavior identification in different conditions to designing and mo...

An air flow meter for measuring the intake air of an automobile engine is presented. It is based on a miniaturized silicon thermal mass flow sensor using a thick porous Si (Po-Si) layer for local thermal isolation from the Si substrate, on which the sensor active elements are integrated. The sensor is mounted on one side of a printed circuit board (PCB), on the other side of which the readout a...
