Scale-Tron has introduced a new touch screen display for its SiloWeigh silo and admix tank inventory system.  With two sizes of touch screen, the 4” can display up to 4, and the 7” up to 16 vessels, showing the levels of the contents as bar graphs plus digital displays of weight in tons or volume in gallons.  The color of the bar changes as alarm level are passed, giving instant visual indication of action to be taken.  User friendly menus allow setting of alarm values as well as initial setup and calibration.

Scale-Tron’s Silex sensors bolt directly onto the legs of a silo to measure the weight of its contents.  When installed on all four legs of a standard silo, the claimed accuracy is better than 2%,  surpassing the best level sensors; measurement is true weight, not a value derived from a volume calculation.  With no moving parts, reliability is excellent.  Installation can be done in one day on most silos and it is not necessary to climb the silo.  A pressure sensor for admixture tanks is installed in the outlet pipe to give volume with high accuracy.  Any mix of tanks and silos can be displayed on the SiloWeigh-II touch screen;  benefits include easy installation and setup, high accuracy, measurement of divided silos and a cost that is said to be low compared with either running out of material or overfilling, with its environmental consequences.

Options include analog outputs for control systems and alarm relay outputs to sound horns, light warning lamps and activate pinch-off valves.  Inputs from pressure switches on the silos can warn of the need to replace filters.
