Operation
Components
Horizontal Sensing Plate
The Millflo reacts to the horizontal component of force
created by the impact of material on the sensing
plate. The Millflo consists of two physical
components:
• the housing which includes the flowguide and
the outlet. It supports the sensing assembly
and guides the material flow.
• the sensing assembly, which includes the
sensing plate and the load cell.

The material travels down the flowguide, striking the
sensing plate and discharging through the outlet. The
force exerted on the sensing plate has both a vertical
and horizontal component. The design of the load cell
is such that it reacts to the horizontal component only;
the vertical component is ignored.
The sensing plate is displaced proportionally to the
material flow and is not susceptible to material build
up, so long as it does not bridge across to the housing.
Positive displacement of the load cell is limited by the
positive stop incorporated in the design of the load cell.
The displacement of the load cell is sensed by its strain
gauges. These convert the excitation signal from the
electronic integrator to produce a signal proportional
to material flow.
