MASS FLOW METERS

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

MULTICOR® MASS FLOW METER

CORIOLIS PRINCIPLE

The 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 affected by material density, friction or in-feed drop height.
  • Flow rates up to 10,500 cubic ft/hr.
  • Continuous weighing, batching and gravimetric feeding applications.
  • Low installed height.

DEFLECTION CHUTE MEASURING PRINCIPLE

The deflection chute measuring system used in our 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%.
  • Ideal for relatively high flow rates of free-flowing or pulverized materials.
  • 30 to 600 tons per hour.
  • Material temperatures from 0 to 500° F (260° C).
MULTISTREAM B-80 SOLIDS FLOW METER

IMPACT PLATE MEASURING PRINCIPLE

The impact plate measuring principle used in the 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%.
  • Compact design - no loss of headroom due to additional chutes.
  • Dust-tight stainless steel housing.
  • Cost effective, simple integration -offset-free arrangement of inlet and outlet.
  • Weighing electronics can be integrated in the mechanical system.
