Nozzle Location - Siemens SITRANS LR200 Guia De Inicio Rapido

• The end of the shield section should protrude a
minimum of 10 mm (0.4") to avoid false echoes being
reflected from the nozzle.
Location on a manhole cover
• A manhole cover is typically a covered nozzle with a
diameter 610 mm (24") or greater.
• For optimum signal conditions, locate the antenna
off-center, typically 100 mm (4") from the side.

Nozzle location

WARNING: For vessels with conical or parabolic tops, avoid mounting the
instrument at the centre. (The concavity of the top can focus echoes into the centre,
giving false readings.)
Note: Under certain circumstances, it may be acceptable to mount the device at the centre of
a flat-topped tank. Please discuss this with your local Siemens representative.
