Using impact plate, measuring chute and Coriolis technologies, SCHENCK Weighing Systems manufactures a family of solids flow meters. Working with SCHENCK application engineers, customers are given the ability to choose the technology, performance level and price that's best for the job.

IMPACT PLATE MEASURING PRINCIPLE

The impact plate measuring principle used in SCHENCK's Multistream B-80 is based on the reactive force generated when a dry material, directed by an inlet pipe, strikes a steel impact plate mounted at a defined angle. The horizontal component of the reactive force is sensed by a load cell and processed electronically into flow rate and total weight values, with accuracies of ±2%.

DEFLECTION CHUTE MEASURING PRINCIPLE

The deflection chute measuring system used in SCHENCK's DLM Solids Flow Meter is also based on reactive force but a curved guide chute is used in place of an impact plate. As a result, impact or shock is replaced by radial acceleration and chute deflection that a load cell detects. This signal is then electronically processed to produce flow rate and total weight values at accuracies generally better than ± 2% and with repeatability of 0.5%.

CORIOLIS PRINCIPLE

SCHENCK's Multicor mass flow meter line uses the science of particle acceleration and its resultant forces to measure flow rate and total weight at accuracies of ± 0.5%. Space efficiency and overall reliability make Multicor an ideal choice for feeding, measuring and batching applications involving reasonably free-flowing dry materials.

Multicor consists of a partitioned measuring wheel, mounted on a drive shaft inside a central dust tight housing. The drive shaft is driven by an electric motor mounted outside Multicor's housing. Material enters the unit through an off-center inlet and discharges through a center outlet below the measuring wheel.

In operation, the measuring wheel rotates at a constant speed. Material entering the unit flows into the top of the measuring wheel and is deflected outward in a radial direction creating a "Coriolis force". Multicor sees this force as a change in torque which is detected by a strain gauge load cell. The output of the load cell is electronically processed to produce flow rate and total weight values at accuracies of +/- 0.5%. Best of all, unlike other flow meters on the market, Multicor's performance is not effected by material density, friction or in-feed drop height.
