Terbold Posts: 6 Rating: (2)	Hi , Ihave a9 m high silo with Hexane andare using the following radar7ML5431-0DB20-1BG1. The measurement is not always stable, there are fluctuation in the reading, in particular diring the filling.I have been told, that a bigger horn would give a higher performance here. Is it possible to change the existing 2 " horn to a 3" or 4 " horn afterwards ? TX !

Ordernumber ==> A5E01151571 I can imagine, that the signalstrength of the2 " horncould be too poorfor a medium with a DK of only 1.9 like Hexane, inparticular if there is a movement at the surface during the filling. Becauseof the DN80flange of your LR250, the 4 " antenna will not fix. Anyhow, the perfomance of the 3" hon will increase the performance also. Please note,that the biggest horn will give you always the best performance. Cheers
