Typical installation and mounting considerations<\/strong><\/span><\/p>\n

\u2022 These statements are intended to be general guidelines and not hard and fast rules.
\n\u2022 The optimal Ultrasonic Level transducer installation is 1\/3 the distance from the side wall and consists of the following:<\/p>\n

* 10:1 Rule \u2013 Typical rule-of-thumb is 1 foot from the sidewall for every 10 feet of bin height.<\/p>\n

* Consider location of the fill stream as well to ensure that is not intersecting the beam path.<\/p>\n

* For obstructions inside the vessel, you should be 1 foot from the obstruction for every 10 feet of distance from the transducer.<\/p>\n

\u2022 All material levels should be considered when selecting the mounting location.<\/p>\n

\u2022 The sound path should be perpendicular to the monitored surface.<\/p>\n

* For liquids, perpendicular to the material surface. This usually means aiming the transducer straight down. (Figure 1).<\/p>\n

* For solids, perpendicular to the angle of repose. This usually means aiming the transducer toward the silo or bin outlet. (Figure 2).<\/p>\n
