Compact Mass Flow Meter Based on a Micro Coriolis Flow Sensor
In this paper we demonstrate a compact ready-to-use micro Coriolis mass flow meter. The full scale flow is 1 g/h (for water at a pressure drop < 1 bar). It has a zero stability of 2 mg/h and an accuracy of 0.5% reading for both liquids and gases. The temperature drift between 10 and 50 °C is below 1 mg/h/°C. The meter is robust, has standard fluidic connections and can be read out by means of a...
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 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 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 کاملA Sub-Optimal Look-Up Table Based on Fuzzy System to Enhance the Reliability of Coriolis Mass Flow Meter
Coriolis mass flow meters are one of the most accurate tools to measure the mass flow in the industry. However, two-phase mode (gas-liquid) may cause severe operating difficulties as well as decreasing certitude in measurement. This paper presents a method based on fuzzy systems to correct the error and improve the reliability of these sensors in the presence of two-phase model fluid. Definite ...
