SMU Silo Patrol

The heart of the SiloPatrol® SSEE Inventory Management System is an industry-leading cable-based “Smart” sensor called the Silo Monitoring Unit (SMU) that is designed to perform in some of the harshest and most dynamic level measurement conditions. The SMU with its state-of-the-art sensors including Hall-effect technology can be combined with a variety of operator interface and auxiliary output options to provide a practical vendor / remote managed inventory system designed for your specific requirements.

When a measurement cycle is initiated, either manually or automatically, the SiloPatrol® SSEE sensor (SMU) motor control system deploys
a plumb bob, that is attached to a heavy-duty stainless steel cable, for descent into the vessel. The motor control circuitry regulates an optimal speed of descent that helps to eliminate cable slack, maximizes motor life and ensures that the plumb bob will stop whenit contacts the material surface. The SMU measures the amount of cable deployed during descent via its unique optical sensing system. Once the optical encoder determines that the plumb bob has reached the material surface, the microcontroller reverses the direction of the motor and transmits the distance value. During the ascent of the plumb bob, the SMU measures the amount of cableretrieved in order to reconfirm the distance measurement.



Flexar® smart guided wave radar sensors operate using TDR (time domain reflectometry) principles. In the application of TDR for process level measurement, radar pulses are focused down to the material surface by the unit's wave guide (a heavy duty cable). The time-of-flight of the pulse and its reflection back to the instrument electronics is directly related to the empty distance in the vessel and the material level. The output from the electronics is continuously updated as the level of the material surface changes.

Flexar® units are suited for almost any application, can operate with process temperatures up to 392˚ F (200˚C), can be provided with a variety of process connections and can work reliably with materials having a wide range of bulk densities and dielectric constants. Flexar sensor technology has also been proven in many difficult applications including those where dust levels make it difficult for other technologies to perform reliably, especially at longer ranges.
