Micro Coriolis Flow Sensor
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 ...
متن کاملMeasurement of Gas-Liquid Two-Phase Flow in Micro-Pipes by a Capacitance Sensor
A capacitance measurement system is developed for the measurement of gas-liquid two-phase flow in glass micro-pipes with inner diameters of 3.96, 2.65 and 1.56 mm, respectively. As a typical flow regime in a micro-pipe two-phase flow system, slug flow is chosen for this investigation. A capacitance sensor is designed and a high-resolution and high-speed capacitance measurement circuit is used t...
متن کاملA Compact Micro Coriolis Mass Flow Sensor with Flow Bypass for a Monopropellant Micro Propulsion System
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...
متن کاملMicro Coriolis Mass Flow Sensor for Chemical Micropropulsion Systems
We have designed a micromachined micro Coriolis flow sensor for the measurement of hydrazine (N2H4, High Purity Grade) propellant flow in micro chemical propulsion systems [1]. The sensor measures mass flow up to 6 mg/s for a single thruster or up to 24 mg/s for four thrusters. The sensor will first be used for measurement and characterization of the micro thruster system in a simulated space v...
متن کاملThe Micro-Pillar Shear-Stress Sensor MPS3 for Turbulent Flow
Wall-shear stress results from the relative motion of a fluid over a body surface as a consequence of the no-slip condition of the fluid in the vicinity of the wall. To determine the two-dimensional wall-shear stress distribution is of utter importance in theoretical and applied turbulence research. In this article, characteristics of the Micro-Pillar Shear-Stress Sensor MPS(3), which has been ...
