METER - 

installation

5.1.5 Agitators presence

The level measurement is possible thanks to the  Auto-Tuned statistical fi lter.

Should rarely need to adjust the fi lter setting by editing 2 METER sensor programming parameters:

- FILTER; this parameter is present in the Quick Setup menu and in the Advanced Confi guration “SETUP” menu;

increasing the parameter value, decreases the sensor sensitivity to the level measurement sudden variations.

- F-WINDOW; this parameter is present in the Advanced Confi guration “SERVICE” menu; decreasing the parameter

programmed value, increases the sensor immunity to false echoes.
