Thayer Scale’s loss-in-weight feeders deliver precise, consistent ingredient control across any material, with easy calibration and built-to-survive reliability.
With over 75 years of experience, we offer the largest range of loss-in-weight feeders of any manufacturer. All of our feeders offer integrated material agitation zones, specialized auger designs and a wide range of proprietary feed algorithms to ensure reliable feeding of even the most difficult materials. When paired with one of Thayer Scale’s rugged, counterbalanced platform or cable scales, the combination is a robust gravimetric feeding solution that integrates seamlessly into existing plant processes.

Achieve consistent, reliable metering at the desired flow rate with our volumetric feeding subsystem
Powered by our volumetric feeding subsystem, our loss-in-weight feeders provide consistent, reliable metering of the target material at desired flow rates. To this volumetric feeder, we pair a fully mass-counterbalanced platform or cable scale for maximum signal and accurate, reliable weight measurement.
Thayer Scale’s powerful set of proprietary add-on accessories help with problematic flow issues, such as bridging, flushing, adhesion, and cohesion. In addition, our instrumentation’s powerful software routines optimize the feeder’s performance, including output compensation, disturbance control, linearization, density compensation during refill, temperature compensation, and automated calibrations.
