Abstract
Official abstract text for this publication.
This method comprises taking a first pressurized gaseous phase sample in a flow channel and transferring the first sample in the measuring channel. It comprises activating a second sensor to collect a first piece of information representative of the first pressurized sample. The method comprising taking a second pressurized liquid phase sample, transferring the second sample in the measuring channel and activating the second sensor a second piece of information representative of the second pressurized sample. The method comprises the computation of at least one calibration coefficient connecting the property to the or each piece of information received from the sensor, based on the first piece of information and the second piece of information.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for calibrating, under flow conditions, a device for measuring at least one property of a pressurized polyphase fluid circulating in a pipe, the property being computed using at least one piece of information received from a first sensor placed opposite the fluid circulating in the pipe, the polyphase fluid comprising at least one liquid phase and a gaseous phase, the method comprising: circulating the pressurized polyphase fluid through a flo…
