Level based flow solution with a pressure sensor mounted on the mains for actual head
compensation
Use either a given static head or mount a pressure sensor on the outgoing mains to get the actual head. If a
pressuresensorismountedinthemainsdischargepipe,thecontrollerwillautomaticallycompensateforany
variances in the head. Having a pressure sensor mounted on the mains can also warn for potential problems
with a high mains pressure.
Suchaproblemcanoccurdueto:
Air entrapment in the mains
High load from other stations
Thiswillthennaturallyhaveanimpactonthecalculationsbutmoreimportantlyonthecostofpumping.
Lifting elevation = 18 m
Mid level 2.5 m from
lowest level
M = 18 m - 2.5 m = 15.5 m
Overflow at 5 m from
lowest level
H = 18 m - 5 m = 13 m
Lowest level 0 m
L = 18 m - 0 m = 18
m
