Case Study
Calcium Carbonate (Powder) : Roofing Shingles
Results: Once the CentriFlow® Meter was installed and the calibration was completed, the meter performed well within the desired accuracy of ±0.25% of the full scale volumetric flow rate. The accuracy of the CentriFlow® Meter allowed for the calcium carbonate filler and liquid asphalt ratio to be controlled within a tight tolerance. This tight control over the operation allowed for major savings in materials as well as a better manu
