15.8.4 Deactivating the damping of the liquid velocity values
By default, the liquid velocity values are not damped.
But if the damping of the liquid velocity values is active, do the following to deactivate it:
→
Go to the
CONFIGURATION
view.
→
SAW sensor
→
Confirm to access the Parameter view.
→
Stand. meas. values
→
Liquid velocity
→
Damping The Current settings are displayed
→
Choose
None
The
New settings
are displayed.
→
Save.
The damping of the liquid velocity values is inactive.
15.8.5 Activating the monitoring of the liquid velocity
Because of a malfunction in the process or in the flow rate sensor, the measured liquid velocity value can be
too high or too low.
A monitored value can be:
• in the normal operating range.
• in the warning range,
• in the error range.
You can set 4 limit values: 2 error limits and 2 warning limits.
→
To set the limit values, see chapter 15.8.7 Changing the error limits, the warning limits and the hysteresis
of the liquid velocity.
Fig. 52 in 15.4.5 explains how the device reacts when the monitored value enters in another range (for
example, from the normal range into the warning range). The reaction time depends on the hysteresis value
and if the monitored value increases or decreases.
By default, the monitoring of the liquid velocity and the diagnostics are all disabled.
To activate the monitoring of the liquid velocity, do the following:
→
Go to the CONFIGURATION view.
→
SAW sensor
→
Confirm to access the Parameter view.
→
Stand. meas. values
→
