Flow-meter for bulk products Brabender Technologie

The Working Principle


Bulk material supplied from above passes a constant-
speed impeller wheel driven by a three-phase current
motor, diverting the material radially. The tangential
Coriolis force acting on the wheel blades causes drive
torque changes in proportion to the flow rate sensed by
a load cell. Based on torque and speed, the Congrav®
microcomputer computes the current flow rate, which is
both displayed and issued as a signal for recording or
control of a variable-speed upstream feeder (e.g.
screw feeder, rotary valve).
