Overview
Process Automation Gamma type mass meters can be applied to screw feeders to provide accurate feed control.

Operation
A screw feeder, designed as a proportioning device, will have a throughput proportional to the rotational speed of the screw - provided that the screw is full at all times with a material of constant bulk density. With the addition of the Process Automation Gamma Mass Meter, the throughput may be more accurately computed by measuring the mass of material in the screw.

The standard Process Automation UNIPRO® signal processor is used with the gamma mass meter fitted to the screw feeder.

Signal processing is performed by our UNIPRO® weighing transmitter.
