5. Flowrate Function
5.1
Real-time Flowrate
Flowrate calculation principle
：
Everytime when start, make note for turn on time
t0
，
start feeding, till empty finish a
whole process. Set discharge value as
DiscVal(1).
Before start the second process, make
note the second start time
t1
，
then will know the time of
dT(1)
，
start the second feeding.
Can calculate Flowrate
Flux= K*DiscVal(1)/dT(1)
through the first time of empty time
and discharge value.
Where: K is the conversion coefficient (because DiscVal(x) is based on system demarcated
Unit and Decimal, dT(x) is displayed as Unit 0.1s, and Flowrate is displayed as t/h or Kg/h,
conversion rules are described below).
Similarly, you can save DiscVal(x) and dT(x)(x=1,2,3,4,5,6) in a column.
If FluxLen (Flowrate window length) is 1, DiscVal(x) and dT(x) are updated every
time DiscVal(x) is executed.
Real time Flowrate
Flux =K*DiscVal(1)/dT(1)
If
FluxLen>1
，
set
FluxLen=n
，
run time is
k
When
k<n
，
the collection queue is not full
Flux=K*(DD…+DiscValk)/(dT1+dT2+…+dTk)
When
k>n
，
the newly sampling data replaces the oldest data, that is, the ACUM in the
queue of the Flowratedata team is the latest N data
Flux=K*(DD…+DiscValn)/(dT1+dT2+…+dTn)
