Mechanical Considerations
Typically the transmitter is top mounted with a
flanged or threaded tank connection, but the probe
can also be installed at an angle of up to 90° from
vertical. When the transmitter is installed, the
housing can be rotated up to 360°.
The probe must be hung, fully extended, through the
entire distance where level readings are desired.
To get best possible performance, the following must
be considered before installing the transmitter:
• Maximum recommended nozzle height is 4 in.
(10 cm) + the nozzle diameter for all probes
except the coaxial. For the coaxial probe there
are no such restrictions.
• Inlets should be kept at a distance in order to
avoid product filling on the probe.
• Avoid physical contact between probes and
agitators as well as applications with strong
fluid movement unless the probe is anchored.
If the probe can move to within 1 ft (30 cm) of
any object during operation then probe
tie-down is recommended.
• Select probe length according to the required
measuring range. Most of the probes can be
cut in field.
However, there are some restrictions for the
standard and HP coaxial probes: these can be
cut up to 2 ft (0.6 m). Probes shorter than 4.1 ft
(1.25 m) can be cut to the minimum length of
1.3 ft (0.4 m).
The HTHP coaxial probe and the PTFE
covered probes can not be cut in field.
• In order to stabilize the probe for side forces, it
is possible to fix or guide the probe to the tank
bottom.
For solids, consider using the 0.24 in. (6 mm)
probe since it has higher tensile strength (see
page Level-14). The probe should have a sag
of
≥ 1 in./100 in. (1 cm/m) to prevent probe
damage.
• Avoid anchoring in solids tanks over 98 ft (30
m) in height. See tensile load table in “Solids”
on page 14.
For more anchoring options, see the Reference
Manual.
