5.6.2 "Linearization settings" menu
One last action possible on the flow is the linearization of the result. Depending on the flow, the flow is
corrected by X % based on a pre-defined table:
The parameter Q ref defines the maximum flow used for the linearization. The points of the table are then
defined as a percentage of this maximum.
The rectifier coefficient must be defined by the user:
- A coefficient of 1 does not change anything in the result.
- A coefficient of 0.8 reduces the value of the flow by 20 % at this point, etc.
There are two tables, one for positive flows and one for negative flows.
5.6.3 "Advanced settings" menu
1) Simulation mode
The flow meter can be used:
 in Measurement mode (normal operation of the flow meter),
 in Velocity simulation mode.
Enter the value of the flow required and the sine wave (as a percentage) applied around this value.
Comment: A modulation of 0 % keeps the flow velocity constant. A modulation of 100 % fluctuates the
simulated velocity between 0 and 2 times the indicated value.
To simulate the level, go to the input/output settings and change the simulation value in the input
corresponding to the level measurement (see chapter dedicated to inputs/outputs).
