The Models 402/402X and 404X/404Z Series, and the Models 405, 406, and 408 'Weight-Loss' Weigh Feeders feature a Platform type weighing system specifically designed by Acrison for continuous or batch weighing of dry solids or liquids on a weight-loss basis. The weighing systems of these particular model feeders incorporate technologically advanced, lever mechanisms (scales) utilizing Acrison designed and manufactured stainless steel flexures for all pivotal connections. Frictionless in operation, these performance-proven weighing systems are extremely stable, rugged, and counterbalanced so that only the net weight of material in the metering mechanisms (and in their supply hoppers or tanks) is accurately weighed. Acrison’s various contollers and control systems encompass the latest technologies and algorithms to ensure optimum levels of performance.


  • Metering Accuracy - is typically +/- 0.25 to 1% or better (error) at two sigma based on a given number of consecutive one minute weighments
  • Versatile - wide range of metering mechanisms are available providing the ability to effectively handle an extremely broad variety of dry solid material.
  • Unique Ratiometric Digital Weight Resolver - is extremely precise, calibration and adjustment-free, and cannot be damaged by any amount of shock or overload the weighing system may experience
  • Weighing Mechanism - extremely stable, ruggedly constructed, and permanently calibrated; longevity is unsurpassed
  • Dust-Tight Construction - provides total product confinement from inlet to outlet
  • All Steel Construction - provides long-term durablitity with minimal maintenance requirements


  • Weighing System:
    • Technologically advanced, state-of-the-art lever network utilizing Acrison designed and manufactured heavy-duty stainless steel flexures for all pivotal connections
    • Acrison Flexures provide optimum structural rigidity of the lever network, frictionless operation and ensure permanence of the weighing system’s accuracy and calibration
  • Ratiometric Weight Resolver System:
