Solid Flow Meter

The Solid flow meter has been developed for the precise, maintenance-free measurement of quantities of free-flowing bulk goods. The physical principle for recording the weight is based on Newton’s Second Law of mechanics.

The solid flow meter has no moving parts. Thus the flow meters are nearly maintenance free. The solid flow meter are very accurate flow meters over a wide product range. Our solid flow meter system is measuring the mass flow by centripetal force. It is not an impact scale. That is important, when measuring bulk materials because the bulk density is changing in most applications. Changes in bulk density and grain size have a big influence on accuracy of impact scales. The solid flow meter system is affected very little by changes in bulk materials compared to an impact scale. The solid flow meter are available in different sizes according to the maximum flow rate.

TiERMAX helps you to select the right solid flow meter for your application.

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.
