3D Silo Volumetric & Profile Detection Solution for Delicate Processes

iSilo™ is perfectly suited for monitoring small to average-sized silos. Based on the award-winning indurad iDRR™ sensor technology, iSilo™ provides real-time information on filling height, 2D/3D illustrations of the silo contents and complete production history on a reliable basis. The several inflow and outflow points of this solution have proven to be an especially helpful feature. In opposition to the iDome™ Solution, iSilo™ is based on a single iDRR™ Sensor.

How does it work?

Solution Layout: One indurad DualRangeRadar (iDRR™) sensor is installed underneath the silo roof. The sensor is connected to the indurad RadarProcessingUnit (iRPU™), which is installed nearby and creates the volumetric information and 3D images of the silo contents.

Why is it an improvement?

Common Technologies to measure the contents of silos all come with a huge number of disadvantages and limitations:

1D Level Gauge Radars

  • Are restricted to single-point probes
  • Automatically assume the surface to be flat
  • Are difficult to adjust mechanically on the roof

Ultrasonic measurement devices

  • Are easily distorted by machine drive noises
  • Have problems with dust clouds, changing temperatures or pressure

Breaking Limitations: iSilo™ pushes the limits for level gauge measurement with regard to information, performance, reliability and accuracy:

  • Provides critical information as multiple area specific min and max set points
  • Provides information about dead material at walls to prevent collapse and ratholes
  • Allows to work under pressure and temperature changes as present in high altitude
  • Allows to work in strong metallic environments with cell-based filters for structural steel beams
  • Flat polycarbonate sensor window with anti-stick surface coating leaves no corner for mud buildup
  • IECEx / ATEX approval for Zone 21, 22 dust ex as well as M2 in UG Coal Mining

What are the Benefits?

Based on the award-winning indurad radar sensor technology, iSilo™ allows for high-precision real-time measurements in silos even in high dust concentration levels, during extreme temperature fluctuations and all other environmental factors commonly encountered in silo environments. It provides:

  • Remote commissioning instead of spending nights on the silo roof
  • Real-time filling height information
  • Automatic selection of input/output gates
  • Prevention against silo downtime
  • 3D illustrations of silo contents (liquid and solid fillings)
  • Highly dynamic scanning cycles of 15 scans/second
  • High/low temperature proof for monitoring dangerous materials such as clinker

Where is it used?

Industries/Materials: iSilo™ is installed in customer sites around the world in a wide spectrum of silos with varying contents. iSilo™ is a highly reliable and worry-free volumetric measurement solution for industries that demand exact and permanently up-to-date information about the development of the contents in their storage facilities for quick reaction times:

  • Material handling, power plants and steel (coal, ore)
  • Mining, stone and soil (rock, sand, gravel)
  • Chemical industry (fertilizer, salt)
  • Agriculture (soybeans, grains, meal products)
