BinMaster Level Controls has introduced a series of extended rotaries for top-of-bin mounting when the rotary is used as a high level alarm. These vertically extended rotaries are desirable as solid material will tend to be higher at the filling point and operators want to prevent filling the bin to the very top and allow for a specified amount of headroom in the bin. For top-of-bin applications, Bin-Master custom manufactures extended rotaries, offering lengths up to 12 ft.
