9.3 Water Meter
For information on the water meter installation, please refer
to the manufactures manual. Pay attention to the installa-
tion position, flow direction and the calming section.
Basic rule: The water meter should have 10 nominal
diameters straight pipe ahead of the meter and 5 nominal
straight pipe diameters after to ensure proper flow through
the meter

9.4 Sacrificial Anode
The LORENTZ Sacrificial Anode is designed for use with
LORENTZ pump ends. Where solar pump ends operate in ag-
gressive water conditions acidic water can attacks the pas-
sive layer of the high quality-steel pump end. This corrosion
reduces the life time of the product. The LORENTZ Sacrificial
Anode contributes to the protection of the pump system
from this type of corrosion and extends the pumps life.
For further information about the Sacrificial Anode please
refer to the COMPASS datasheet.
