The Model MSV gravimetric feeder from Thayer Scale pairs a rugged, economical volumetric feeder with a low-profile, mass-counterbalanced scale, resulting in a gravimetric feeder that provides highly responsive feed-rate control and accuracy in a small form-factor package. It reportedly offers precise rate control for free-flowing pellets and granules. Its design is compact, easy to clean, and economical, providing flexibility and efficient use of floor space. 

The new MSV feeder includes Thayer Scale’s low-profile cable scale, which utilizes a micro-lever system that counterbalances the tare weight, resulting in load-cell utilization significantly higher than other options. The higher load-cell utilization provides numerous benefits, including higher accuracy, typically 0.25% of feed-rate, fast responsiveness to changes in set point or material density fluctuations, resulting in higher accuracy material delivery and the elimination of “dead zones” common in gravimetric feeding applications.

Higher load-cell utilization also enables the MSV feeder to operate with longer gravimetric cycles, requiring fewer refills and a lower percentage of the gravimetric cycle operating in volumetric or “settling” mode. 
The system is designed to operate with the Thayer Scale Differential Screw solution, enabling consistent, pulse-free delivery of material across a wide operating range.
