3D from BinMaster

Get connected to your inventory with the only level sensor that measures and maps multiple points on the material surface. A 3D image representing the topography inside the silo indicates buildup, cone up or down conditions. 3DVision software accounts for irregular material surfaces when calculating volume.

The 3D Level Scanner’s acoustics-based technology penetrates dust ensuring reliable measurements. This non-contact technology accurately measures solids and powders, including low-dielectric materials. It is hazardous location certified for CFM Class I & II and IECEx/ATEX.

And you can get it only from BinMaster.

Acoustics-based technology

The 3DLevelScanner uses acoustics-based technology. Three transducers send extremely low frequency sound waves to the material surface, making a sound that sounds like chirping crickets. The sensor receives echoes back from multiple points on the surface which are converted to distance measurements.

Advanced algorithms in the software assign each measurement an XYZ coordinate that is mapped into a 3D image. Optional software generates a graphical representation of the material topography in the bin. Surface variations are accounted for in volume calculations.

What makes the 3D Scanner unique?

  • Measures multiple points on the material surface
  • Generates a 3D image of the material topography
  • Volume accuracy surpasses any single-point device
  • Reports minimum, maximum, and average distances
  • Detects cone up or down conditions
  • Sees sidewall buildup that could cause structural damage
  • Measures topography in segmented silos
  • Accurate volume in large bins using multiple scanners


View Multiple Bins on One Screen

Installed on a local network, easy-to-use MultiVision software gives plants the ability to view multiple bins in a single window. Automated high or low-level alerts simplify inventory oversight. With one click, users can zoom into detailed information and the 3D profile for a single bin.

Why Plants Like MultiVision

  • All users view the same inventory data
  • Inventory updates automatically
  • Each user can customize their screen
  • Compatible with all 3DLevelScanner models
  • Reports valued by purchasing, finance, and logistics

3D Models

M Maps and Measures

The M model takes measurements within a 70° beam angle. It reports the highest, lowest, and average level. 3DVision software provides highly accurate level and volume data.

MV Adds 3D Image

The MV has all the capabilities of the M model, but also generates a 3D representation of the material surface. Plants that work with materials that bridge, rat hole, or build up along bin walls may prefer to add 3D imagery.

MVL Measures Big Bins

The MVL provides volume accuracy in large diameter bins. Mount multiple scanners in strategic locations to account for surface variations across the material surface. The software synchronizes the level data from all sensors to create a single 3D image and calculate bin volume.

S for Average Volume

The S model determines the average volume of stored materials based on a 30° beam angle. It is used to measure materials in silos up to 14’ diameter and 200’ tall.

RL Single-Point Measurement

The RL model measures at a 15° beam angle and reports a single distance. It excels in harsh, high dust environments and problematic low dielectric materials. It provides reliable level data and is most frequently used in narrow silos or silos with structure.

HT for High Temps

With an operating temperature up to 356°F (180°C), the HT model is suited for materials like clinker, fly ash, frac sand, and alumina.

**Note: The M and MV can be used on larger diameter bins than specified, but with decreased accuracy since the beam angle will not span the entire surface. The MVL is used on large diameter bins to increase volume accuracy.

A solution for every situation

0° Mounting Flange

The 3DLevelScanner mounts through an 8-1/2” or larger opening in the bin roof. To secure and stabilize the sensor on flat bin roofs, a 0° mounting flange suspends the transducer into the bin while keeping the sensor head outside of bin for programming access.

Angled Mounting Flange

It is essential the 3DLevelScanner mounts vertically and perpendicular to the ground. To ensure the sensor installs properly on angled bin roofs, BinMaster offers mounting flanges for 5°, 10°, 15°, 20°, and 30° angles.

Neck Extensions

The 3DLevelScanner optional neck extensions lower the transducer assembly below structure or obstacles that may interfere with operation. Neck extensions also are used for mounting on thick cement bin roofs or on a raised socket where distancing the head from the transducer is necessary.

Neck extensions come in 1’, 2’, 4’, 6’, and 10’ lengths. They are available with galvanized or stainless-steel pipe. If desired, the extension pipe can be supplied and machined by the customer.
