Multicor ® Coriolis Mass Flow Meters
The Multicor ® Coriolis Mass Flow Meter products provide accurate measuring and feeding of high capacity free to moderately
flowing dry materials for industries such as plastics, chemical, food, grain, pet food, and building materials. High
accuracy, repeatability, and simplicity are some of the critical requirements for measuring and feeding in these process
industries. Schenck AccuRate’s Multicor ® S-80 and S-160 are designed and built upon meeting those needs.
The Multicor ® is a robust, dust tight, in-line direct mass flow measuring device that is not influenced by variations in
material properties, outside forces or plant disturbances. Installs almost anywhere for continuous flow rate measurement,
totalizing, batch control, and continuous feeding. Space-saving, compact design requires no pre-bin, counterbalancing
or damping systems.
Schenck AccuRate offers a variety of controls to go with the Multicor ® products for measuring, feeding, and automatic
on-stream calibration. Fieldbus interfaces including Profibus, DeviceNet, Modbus Ethernet TCP, and AB Ethernet/IP are
also available.
Top 10 Reasons To Buy A Multicor ®
1. Accuracy – utilizing the benefits of Coriolis technology, very high and fast measuring accuracy is achieved.
2. Compact Design – perfect for applications with limited space requirements.
3. Dust Tight Housing – reduces the risk of air borne materials that may cause health and safety hazards.
4. Direct Weighing Technology – outside forces or typical plant disturbances have no effect on measuring and
feeding accuracy.
5. Repeatability – changes in physical material properties do not influence the measuring result and system
accuracy.
6. Simple Verification and Calibration - automatic on-stream check system allows for on-line verification and
calibration without process interruption.
7. Reliable – robust construction ensures long-term operational reliability and minimal downtime.
8. Low Maintenance – efficient design with minimal moving parts requires virtually no maintenance.
9. Simple Installation – without complex platform structures, isolation devices, or external enclosures.
10. Economical – we challenge you to compare the total installed and operating costs of the Multicor ® to any other
solution out there!

Multicor ® Coriolis
Mass Flow Meters
Typical Applications
The benefits of the multicor ®
Coriolis mass flow meter
• By design, the Multicor ® is not affected by changes in
material characteristics such as:
– Density
– Drop Heights
– Material Friction
– Impact Characteristics
Other types of flow meters are typically affected by
changes in material characteristics, which can increase
error percentage and may require the operator to
recalibrate the equipment more frequently.
• Capable of achieving theoretical accuracy and repeatability
of ± 0.5% or better when the flow rate exceeds 2.0 metric
tons per hour.
NOTE: Actual accuracy and repeatability is subject to specific
application parameters and material characteristics.
• Large Capacity – flow rates of up to 160 metric tons per hour
can be reached.
• Compact design is perfect for applications involving
limited space.
• Measures mass flow directly.
• Self-cleaning rotor; low maintenance.
Multicor ®
applications:
• Weighing or tracking inventory of
bulk solids.
• Feeding bulk solids into mills,
extruders, and other process equipment
with the addition of a prefeed device.
• Batching for load-out stations,
mixers, etc.
• Prefeeder control (rotary feeders,
screw feeders, and air slides).

mass flow feeder configurations
Combined with a suitable prefeed device, the Multicor ® makes an excellent mass flow feeding system. Selecting the optimum prefeed
device based on the material characteristics and application requirements will ensure the highest short-term feeding accuracy and
reliability. Below are some common configurations with the Multicor ® and a prefeed device.

Metering /
totalization
Multicor ® can be used
to calculate totalized
amounts of material
from the user’s process.
System will allow user’s
to maintain tight inventory
levels and verify
material amounts added
to their process.
Controlled flow feeding
Multicor ® feeds material to a set point by controlling rotary feeder throughput.
Screw Feeder
SCREW FEEDERS
For poor flowing additives with low feed rates,
screw feeders provide precision accuracy over
a wide control range. The screw feeder offers
flexibility in plant layout with its adjustable
length and angle. Screw feeders also provide a
higher downturn ratio than rotary feeders.
Load-out
application
In a typical load-out application
the Multicor ® measures material
extracted from a silo by a
rotary feeder and
screw
feeder.

is applied. Rotary feeders are also compact
devices and have a low power rating.

Multicor ® Coriolis
Mass Flow Meters
The Coriolis principle
Schenck AccuRate’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% or better. Space efficiency and
overall reliability make the Multicor ® an ideal choice
for feeding, measuring, and batching applications
involving reasonably free-flowing dry materials.
The 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 the Multicor ® ’s housing.
Material enters the unit through an off-center inlet
and discharges through a center outlet below the
measuring wheel.

Specifications / Coriolis Principle
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.” The
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,
the performance of the Multicor ® is not affected by
material density, friction, or in-feed drop height.
