up to approx. 80 °C. It is particularly recommended to follow this advice during meter
calibration. In absence of cavitation, the flow sensor is typically functioning at lower
operating pressure. See also

2)
ULTRAFLOW® must not be exposed to pressure lower than the ambient pressure (vacuum). This minimises the risk
of transducer damage.
Pressure loss:
Consider the pressure loss of the installed flow sensor for dimensioning of pumps in
your installation. For further details, see

IP6X means that persons handling the instrument are protected against access to hazardous parts even when dealing
with a thin wire of 1.0 mm diameter. In addition, the inside of the instrument is protected against ingress of dust (dust-
tight).
3)
IPX5 means that that the instrument is protected against water jets coming from any directions to the enclosure.
For the Cable Extender Box, this means that the IP class is higher than required by EN 1434 for other enclosures, which
are not to be installed in pipe work. Note that it is the responsibility of the installer to ensure proper mounting of the
cable screw connections as otherwise the IP classification is not valid. Flow sensor and Cable extender box are not
protected against periodically or permanently wet conditions and must not be submerged.
3)
IPX7 means that ingress of water in quantities causing harmful effects are not possible even when the enclosure of the
instrument is temporarily immersed in water.
For Pulse Transmitter/ Pulse Divider, this means that it is well protected and durable in periodically wet conditions. It can
tolerate to be submerged for max 30 min, but only in case of proper mounting of the cable screw connections. It is the
responsibility of the installer to ensure proper mounting of the cable screw connections as otherwise IP classification is
not valid (see
6.11.2.2.4 Cable screw connections
).

When installing a thermal energy meter, the installation recommendations of all three sub-assemblies, i.e. flow sensor,
temperature sensor set and calculator, must be considered. This applies in particular when a temperature sensor is
directly mounted in the flow sensor and when a calculator is mounted directly on a flow sensor.
