Mechanical Installation
2.2 Introduction
This section describes the mechanical installation. Start by reading the General Installation
Requirements for your antenna. This includes Nozzle and Free Space Requirements. The last part of this
section includes mounting instructions for all antenna types, including special requirements for still
pipe/bridle installations and applications.
2.2.1 Tools
The following set of tools are needed for installation of a Rosemount 5600 Series Radar Level Transmitter:

Screw driver

Adjustable wrench

Allen key

Circlip plier (snap ring plier)

Hook spanner (comes delivered with the transmitter)
2.3 General installation requirements
Position the transmitter in a way that allows the microwaves to propagate without disturbance from the
tank wall. In order to achieve optimum performance you should consider the following recommenda-
tions:

Try to avoid obstacles in the radar beam.

Mount the transmitter away from pipe inlets which cause turbulent conditions.

Choose as large antenna as possible to ensure maximum antenna gain.

For best measurement performance it is recommended that the antenna tip ends outside the nozzle,
see
Figure 2-2 .
2.3.1 Customer-supplied flanges
The simple design of cone antennas tank connection allows the use of customer supplied flanges. If a
hole is drilled in a standard blind flange the pressure performance may be reduced. In such a case the
flange should be marked with new rating for Maximum Allowed Working Pressure (MAWP).
2.3.2 Nozzle requirements
In order to allow the microwaves to propagate undisturbed, the nozzle dimensions should be kept within
the specified limits for the different antennas.
