above the feeder, which must be replenished with material from time to time, without interrupting the dispensing process. The whole mechanical system (including the hop-per) must be weighed to allow the loss of weight principle to operate. The ability of loss of weight feeders to provide a contin-uous delivery of material at a predetermined ...
The filter should be programmed to recognize also strong disturbances and take action in consequence. If the feeder is not anymore able to calculate accurately a loss of weight, it will turn automatically to volumetric feeding, fixing the speed of the dosing tool.Such measure is an approximation and can only be acceptable if the feeder stays in volumetric mode for a short time.
The demand for greater accuracy in analytical instruments has prompted the automation of sample and solution preparation based on the more accurate 'solvent weight' to 'sample weight' gravimetric feeder method. A gravimetric feeder is a self-calibrating feeder system that doses based on the weight in speed.
