Notes:
1. Beam should not detect bin bottom.
If this occurs, use range extension parameters (on transceivers where available) to omit false
echoes.
2. Sound beam must be perpendicular to liquid surface.
When mounting the standpipe and flange, you must ensure that the transducer face will be
parallel with the liquid's surface. Refer to Standpipes (Page 37).
