Rosemount 5300 Series
Level-16
• For optimal single lead probe performance in
non-metallic vessels, the probe must either be
mounted with a 2-in. / DN 50 or larger metallic
flange, or be screwed into an 8-in. (200 mm)
or larger metal sheet (see the Reference
Manual for placement).
• Installation on a thick concrete silo must be
made flush with the lower edge, with metal
shielding (see illustration to the right).
• If there is a chance the probe comes into
contact with a wall, nozzle or other tank
obstruction, the coaxial probe is the only
recommended choice.
Minimum clearance is given in the table below.
• For solids: Installation of probes is preferably
carried out when the silo is empty.
Check the probe regularly for defects.
For more information on mechanical installation, see
the Reference Manual (document number
00809-0100-4530)

(1) Requires special configuration and setting of Upper Null Zone and may affect the maximum measuring range..
(2) Minimum clearance from tank bottom for the coaxial and rigid single probes is 0.2 in. (5 mm).
(3) The centermost lead must be at least 0.6 in. (15 mm) away from the pipe/bypass wall.
(4) The probe must be centered in the pipe/bypass. A centering disc (see “Centering Discs” on page 13 and “Ordering Information” on page 32) can be used to
prevent the probe from contacting the bridle wall.
