7.5.1
Flow sensor orientation
In installations in humid environments, you must always be careful to avoid water penetration in the meter electronics.
In general, wires/cables must hang freely downwards after cable connections to form a drip nose for drainage of water
and condensation. By horizontal installation, the plastic housing of ULTRAFLOW® 54/34 must be 45° around the
pipe axis and ULTRAFLOW® 54 (Type 65-5-XXHX-XXX) must be positioned on the side (see

Figure 19. Orientation of (a) ULTRAFLOW® 54 and (b) ULTRAFLOW® 34
as well as (c) ULTRAFLOW® 54 (Type 65-5-XHXX-XXX) around the pipe axis
in humid environments at horizontal installation.
ULTRAFLOW® 34 can be installed in environments with periodically condensing humidity, but ought neither be insulated
nor enclosed as condensation formed around the meter is thereby entrapped. Should you after careful consideration
decide to insulate ULTRAFLOW® 34 after all, the electronics case must at least remain uninsulated.
7.5.2
Orientation of Pulse Transmitter and Pulse Divider
Mounting Pulse Transmitter and Pulse Divider, the cable connections must always be horizontally or downwards oriented
in order to avoid the risk of water and condensation being led into the electronics box via the cables. This is especially
important in moist environments.
Furthermore, wires/cables must in general hang freely downwards after cable connections to form a drip nose for
drainage of water and condensation.
