Hopper Scale or Flow Scale Datasheet

Frequently Asked Questions

What is a hopper scale?


A hopper scale is an industrial weighing system designed to measure the weight of bulk materials stored or transferred through a hopper. It uses load cells to provide accurate weight data for materials such as seeds, grains, powders, or pellets. Hopper scales are commonly integrated into automated processing lines for batching, inventory control, and flow monitoring.



What is the principle of hopper weighing system?


The hopper weighing system operates based on the principle of load cell technology. When bulk material is loaded into the hopper, the weight is transferred to load cells mounted beneath the hopper. These load cells convert the force into electrical signals, which are processed by a control system (such as a PLC) to display and manage weight readings in real time.



What is a hopper scale or flow scale used for?


A hopper scale or flow scale is used to monitor and control the flow of bulk materials through a processing system. These scales are essential in seed cleaning plants, grain handling systems, and industrial facilities where accurate material weighing, batching, and throughput control are required. They ensure product consistency, reduce waste, and optimize production efficiency.



What is a flow scale used for?


A flow scale is specifically used to measure the continuous flow rate of bulk materials, typically in tons per hour. It enables real-time monitoring of product throughput and is often integrated with SCADA or PLC systems for automated extraction, alarm notifications, and operational control. Flow scales are widely used in agricultural processing, feed mills, and bulk material logistics.
