ABSTRACT:
A device for installation on the auger filler cone of dry product dispensing equipment which comprises one or more ultrasonic resonators arranged so as to measure the acoustic impedance of the product within the auger filler cone without interfering with the flow of the augered product. The acoustic impedance can be calibrated to give a density measurement. The device is particularly well-suited for measuring the density of a dry product in the dispensing equipment used in the packaging industry, where a specified amount by weight must be dispensed into containers. Since an auger-type filling machine dispenses a precise volume for each degree of rotational movement of the auger, constant monitoring of the density of the product within the auger cone allows the weight of the dispensed product to be rapidly and accurately determined during the filling process.
