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.
