The Dynatrol® GSS Level Detector is designed for application to either high, intermediate, or low-point level detection of bulk solids","The GSS Level Detector is constructed to handle extremely light weight applications that are difficult to measure or detect a reading. Reliable operation can be achieved with this control where other types of controls may fail to operate.","Versatile:This level detector operates successfully with consistent results on difficult product applications such as fine, low density powders and materials as light as ½ lb. per cubic foot.","No Adjustment Required:All level switch components have been constructed for long operating life and require no field adjustments.","Simple Installation:Simple installation is made in the tank side through a 3\/4\" half-coupling at the point of desired level detection.
