A BLH Nobel customer's manufacturing process included multiple critical tanks that required regular weight calibration. The largest, a reactor, weighs 60 tons. Traditionally, they calibrated the vessels by filling them with water, a laborious and expensive process. It took a week for each tank. Aside from filling the tanks, each must be emptied and rinsed. Finally, calibration required thorough drying before resuming production.
BLH Nobel developed a method to elevate the vessels and read the weight change at various stages of the process. This video demonstrates that method.
BLH Nobel's solution allows the calibration of a weighing vessel, silo, or tank in a fraction of the time compared to using flowmeter or weighbridge calibration. BLH Nobel jacks the tank using hydraulics instead of loading with weights or flowmeter. Typically they measure the result in several points and verify the weighing result. BLH Nobel's method is often carried out without modifying the existing frame or structure, as most already have a suitable jacking point at each load cell.
