Solid Flow Meter
The solid flow meter has been specifically engineered for accurate, maintenance-free measurement of free-flowing bulk materials. Its design leverages Newton’s Second Law of mechanics to precisely record weight, making it a reliable choice for industrial applications.
One of the standout features of the solid flow meter is its innovative design, which includes no moving parts. This ensures that the solid flow meter requires minimal maintenance while providing exceptional accuracy across a wide range of products. Unlike impact scales, which are significantly influenced by changes in bulk density and grain size, the solid flow meter system measures mass flow using centripetal force. This unique approach minimizes the impact of variations in bulk materials, delivering highly consistent and dependable results.
Inside the solid flow meter, the material flows over a specially designed curved slide, generating a centripetal force that is directly proportional to the flow rate. Thanks to the advanced force transmission to the load cell, the measurement remains highly accurate, regardless of product density, grain size, or friction. Additionally, the solid flow meter system can be pre-calibrated at the factory for optimal performance.

Solid flow meter
The actual throughput (kg/h or t/h) and the accumulated absolute quantity (kg or t) can be read from the graphic display. The typical system error is +/- 0.5 % (optimum value 0.3 %) from the measurement area. The measuring range of the different solid flow meter sizes starts at 30 kg/h and ends at 300 t/h.
The Solid flow meter system thus offers an extremely accurate, maintenance-free throughput monitoring for all free-flowing solids (product density: 0.02 – 3.5 kg/l). Strongly fluctuating or pulsating transport speeds have minimum effect on the accuracy of measurement. For products which tend to leave deposits, an automatic, electronically powered dust removal system, which uses air jets to remove dust from the measurement slide, is integrated into the device.
By choosing the solid flow meter, you gain a dependable, low-maintenance solution for monitoring free-flowing solids with precision and efficiency.
