Gravimetric & Volumetric Measurement

Verifiable, quantifiable and reliable measurements

When picking the correct system or retrofit, several aspects need to be taken into consideration. Some of these include tolerance, time allowance, and specific process details. We don’t ask you to think of the idiosyncrasies that will make your process successful, Nol-Tec has the knowledge and longevity to identify details so you don’t have to.

Nol-Tec’s Gravimetric & Volumetric Measurement – the difference

While there are many different ways how your material is fed, measurement boils down to either volumetric or gravimetric.

  • Volumetric is where you measure your material by its volume. Because weight is not being measured a scale is not used but rather a level probe that informs the feeding device to stop the flow once the sensor is tripped. This method is less expensive but, again, provides less specific measurement.
  • Gravimetric is where you measure your material by weight. A scale is involved at the bottom of the device and electronically alerts the feeding method to 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.
