How our gravimetric and volumetric measurement works

While there are many different ways material can be fed, measurement boils down to two types: volumetric and gravimetric.

Volumetric
In this process, material is measured by volume. Because weight is not being measured, a scale is not used but rather a level probe informs the feeding device to stop the flow once a sensor is tripped. This method is less expensive, but provides less specific measurement.

Gravimetric
This process measures material by weight. A scale is involved at the bottom of the device and electronically alerts the feeding method to either adjust the rate, or close once a specific amount is met. This method is more expensive but provides a verifiable, quantifiable means of measuring your material.

The method chosen is completely dependent on your process which can change with new industry demands. Whether you are needing a new system that includes measurement or changing your process from volumetric to gravimetric Nol-Tec has tried and true experience with both applications making your system immediately reliable.

 

Nol-Tec's gravimetric and volumetric measurement — the difference

  • Our technology offers verifiable, quantifiable and reliable measurement to meet your requirements either set by your company or by local regulations
  • We offer the flexibility to retrofit your system between gravimetric and volumetric; ensuring all details are taken in consideration so your system provides measurements that are stand alone and not impacted by outside sources
  • Nol-Tec has over 30 years in system controls which furthers our ability to deliver consistent measurement and integration within your process
