Term Definition
FeedFactor This is a calculation made by the controller
after every weight conversion that gives an
indication of the maximum flow rate of the
feeder when drive command is equal to 100%
It is calculated as:
FeedFactor = (MF/DC%)*100 where
MF= Massflow and DC = Drive Command.
Feedrate This is the massflow output of the feeder.
Gravimetric control The control is automatic. That is, the
massflow is compared to the setpoint, and if
different, a change in drive command will
occur.
Massflow Standard
Deviation This is the variance of the massflow value as
calculated by the controller.
Measured Standard
Deviation This is the variance of the weight values
captured from the weighing system.
Refill Complete
Weight The point, by weight, at which the refilling
will stop.
Refill Request Weight The point, by weight, at which the refilling
will begin.
STP Sample time period is the length of time for a
weight sample to occur.
Tare The weight of the feeder and hopper, less
material.
Volumetric control The control is manual. That is, the massflow
is calculated if possible, but no comparison to
Setpoint is made and the Drive Command
remains fixed.
