Impact Weighers

Australian-Made reliable impact weighing systems.

Improve accuracy, reduce waste, and optimise process control onsite with SRO Technology’s robust, Australian-Made impact weighers. Designed for minimal maintenance and seamless integration, our systems provide precise, real-time measurement of bulk materials – helping you make better decisions, control costs, and maintain consistent product quality.

Impact weighers (also known as impact flow meters) measure material flow rate and totalised weight as product free-falls onto a calibrated impact plate. Unlike traditional conveyor belt weighers, impact weighers are ideal for vertical or inclined applications, making them ideal for compact spaces or gravity-fed processes.
