Inlet and outlet runs
Inlet run: typically  5 × DN
Outlet run: typically  2 × DN
Length of connecting cable
• The permissible cable length L
max
for the remote version depends on the conductivity of
the medium →  19.
• A minimum conductivity of 20 μS/cm is required to measure demineralized water.
