Page 8: Description
The echo is processed by the SITRANS LU180 using Siemens' proven ‘Sonic Intelligence’ techniques. Filtering is applied to help discriminate between the true echo from the material, and false echoes from acoustical and electrical noises and agitator blades in motion. - Page 9 Description SITRANS LU180 Operating Instructions, 06/2016, A5E37100674-AA...
