Low-Maintenance Continuous Level Measuring System

The Series DBOB is a low-maintenance, electromechanical device designed for the continuous measurement of level or volumes in silos, tanks, or hoppers. The DBOB utilizes an internal motor that drives a weight suspended by a firm stainless steel tape down to the bulk material level. Upon reaching the material, the unit reverses and the weight is drawn back into the upper stop position. The distance the weight descends is electronically measured based on the internal rotations of the unwinding tape. The DBOB is user-programmable to output either a height signal or a volumetric signal based on the vessel geometry. The unit’s two programmable relays offer even more customization. The 1½-in. NPT process connection allows for simple installation on horizontal surfaces and an optional aiming flange is available for inclines.
