Abstract
An evaluation system for evaluating a flow rate of a fluid coming from a tank, the system including measurement device suitable for measuring a fluid level in the tank and including estimation device for estimating the flow rate of the fluid using an unscented Kalman filter, the estimation device including an obtaining device for obtaining the raw fluid flow rate and correction device connected to the obtaining device and to the measurement device and configured to correct the raw flow rate as obtained by the obtaining device as a function of the level measured by the measurement device. A method performed by such a system.
Claims15
An evaluation method for evaluating a flow rate of a fluid coming from a tank, the method comprising:
- measuring a level of the fluid in the tank;
- and
- estimating the flow rate of the fluid by using an unscented Kalman filter, said estimating comprising obtaining a raw fluid flow rate value and, when a level measurement is available, correcting the obtained raw flow rate value as a function of the level measurement.
An evaluation system for evaluating a flow rate of a fluid coming from a tank, the system comprising:
- a detector suitable for measuring a fluid level in the tank;
- and
- circuitry configured to estimate a flow rate of the fluid using an unscented Kalman filter by obtaining the raw fluid flow rate and correcting the obtained raw flow rate as a function of the level measured by the detector.
