ThecontinuousowmeasurementisbasedonthefactthatthePC441cancalculatethevolumebymeasuring
theleveldi󰀨erenceduringasetcalculationtime.Forthiscalculationistoexactitisnecessarythatthearea/
levelshouldbealwaysknown.Thiscanbeachievedbysettingthelevelandareaforalllevelwherethepit
changesshape,upto9breakpoints+theareaatzeropointcanbeset.

Example for area calculation:
Rectangle Circle
A = L * W Ex. A = pi * r

Ex.
A =Area A =? A =Area A =?
L =Length L =2.20Meter pi =3.14... D =2.50meter
W =Width W =1.75meter R =Radius=D/2 R =2.5/2=
1.25 meter
A =2.2*1.75 A =3.14*(1.25)
