Pacific Sensor Technologies supplies 3D level scanner to food processor got accurate volume measurement

Pacific Sensor Technologies  supplied a 3D level scanner to a food processing customer who needed accurate bin volume measurements in their operation.
 
The food processor needed highly accurate volume measurements in order to know when to prepare to refill the bin, as the bin was almost always emptied completely before being filled again to prevent damage to the material.
 
Seeking both accuracy and stability at batch empty rates of approximately one-half ton per minute, the customer was primarily interested in headroom or distance to product from the top of the silo. The material was very dusty and prone to sidewall build-up and bridging with the material surface being characterised by highly uneven topography during the emptying process.
 
The 3D level scanner solution was evaluated against radar systems from several different vendors.
 
The MV model of the 3D level scanner was mounted on a 100’ tall x 27’ diameter carbon steel silo containing granular rice. The device was mounted on an existing flange using the BinMaster’s adapter plate and mounted one-sixth in from the silo diameter. The silo has a centre fill, centre discharge configuration.
 
The low frequency acoustics-based technology was able to penetrate the extremely dusty internal bin environment. Unlike the single point measurement radar devices, the 3D level scanner samples multiple measurements within a 70-degree beam angle inside the bin.
 
The customer was able to more closely manage inventory and schedule refilling at an optimal time and provide a more accurate estimate of bin volume by allowing material to settle in the bin and then visually mapping the contents. Based upon the success of the first silo, 27 units of the 3D level scanner were installed at the location.
 
Key benefits of MV model 3D level scanners:

  • Sampling measurements from multiple points provides a more precise headroom measurement and bin volume than a single point measurement device
  • Advanced mapping and visualisation software available on the MV model is helpful when used in material prone to sidewall build-up and bridging
  • Calculating volume after an empty or fill cycle, when there is a ‘cone down’ or ‘cone up’ is more accurate when multiple point measurement is done
