2 Transmitter overview

2.1 Measurement principle

The Rosemount 5408 is a two-wire transmitter for continuous level measurements using
fast-sweep Frequency Modulated Continuous Wave (FMCW) technology.

The transmitter continuously emits signal sweeps with a constantly varying frequency
towards the product surface. Since the transmitter continuously changes the frequency of
the transmitted signal, there will be a difference in frequency between the transmitted
and the reflected signals (see Figure 2-1).

The frequency of the reflected signal is subtracted from the frequency of the signal
transmitted at that moment, resulting in a low frequency signal which is proportional to
the distance to the product surface. This signal is further processed to obtain fast, reliable,
and highly accurate level measurements.

2.2 Process characteristics

2.2.1 Dielectric constant

2.2.2 Foam and turbulence

A key parameter for measurement performance is reflectivity. A high dielectric constant of
the media provides better reflection and enables a longer measuring range.

Foaming liquids or turbulence may cause weak and varying surface echo amplitudes. The
effects of turbulence are usually minor, but in the most challenging conditions, the

10 Reference Manual

Reference Manual Transmitter overview

00809-0300-4408 April 2022

transmitter may be mounted in a still pipe. In addition, measurement performance can be
optimized by configuring the appropriate process conditions settings.

Measurement in foamy applications depends largely on the foam properties. When the
foam is light and airy, the actual product level is measured. For heavy and dense foam, the
transmitter may measure the level of the foam’s upper surface.

The Double Surface Handling function allows the user to select if the foam layer or product
surface should be used as output.

Process conditions
Double surface handling

2.2.3 Dust

Dust is often present in solids applications, and even if the non-contacting radar is not
affected by the dust in the vapor space, dust can be sticky and create a layer on the
antenna. If this layer becomes too thick, it may affect the measurement. This is best
managed by using air purging.

2.2.4 Solid surface

Solids have some common characteristics which may cause weak and varying surface
reflections. The surface is rarely flat or horizontal, the angle of the sloping surface differs
during filling and emptying, and the dielectric constant of many solids is fairly low. Table

2-1 presents common characteristics of some solids applications.

The parabolic antenna is ideal for applications with weak surface reflections. A larger
diameter concentrates the radar beam and ensures maximum antenna gain. The parabolic
antenna comes with a swivel connection that adjusts for angled tank roofs.

2.3 Vessel characteristics

2.3.1 In-tank obstructions

The transmitter should be mounted so that objects such as heating coils, ladders, and
agitators are not in the radar signal path. These objects may cause false echoes resulting in
reduced measurement performance. However, the transmitter has built-in functions
designed to reduce the influence from disturbing objects where such objects cannot be
totally avoided.

Vertical and inclined structures cause minimal effect since the radar signal is scattered
rather than directed back to the antenna.

2.3.2 Tank shape

The shape of the tank bottom affects the measurement signal when the product surface is
close to the tank bottom. The transmitter has built-in functions which optimize
measurement performance for various bottom shapes.

2.4 Application examples

The Rosemount 5408 is ideal for level measurements over a broad range of liquid and
solids applications. The transmitters are virtually unaffected by changing density,
temperature, pressure, media dielectric, pH, and viscosity. Non-contacting radar level is

12 Reference Manual

Reference Manual Transmitter overview

00809-0300-4408 April 2022

ideal for harsh conditions such as corrosive and sticky media, or when internal tank
obstructions are a limiting factor.

Storage and buffer tanks

The Rosemount 5408 provides accurate and reliable level measurement for both metallic
or non-metallic vessels containing almost any liquid (e.g. oil, gas condensate, water,
chemicals).

Reactors

The Rosemount 5408 is ideal for the most challenging applications, including reactors
where there can be agitation, foaming, and condensation, as well as high temperatures
and pressures.

Blenders and mixers

The Rosemount 5408 can help you withstand the rigors of blenders and mixing tanks. Easy
to install and commission, it is also unaffected by virtually any fluid property change.

Rosemount 5408 Level Transmitter 13

Transmitter overview Reference Manual

April 2022 00809-0300-4408

Open atmospheric applications

The Rosemount 5408 measures reliably in open applications, from short range sumps or
ponds to long range dams.

Still pipe and chamber installations

The Rosemount 5408 is a great choice for level measurement in tanks with small diameter
still pipes. It may also be used in chambers, but guided wave radar is generally the best fit
for these applications. For more information on using the Rosemount 5408 in still pipes
and chambers refer to the Best Practices for Using Radar in Still Pipes and Chambers

Technical Note.

Bulk solids

The Rosemount 5408 is the ideal solution for small- to medium-sized silos with rapid level
changes. The narrow beam avoids internal obstructions while still keeping good level
measurement.

2.5 Components of the transmitter

Figure 2-3 shows the different components of the transmitter. There are different antenna

types and sizes available for various applications.

3.3.2 Free space requirements

If the transmitter is mounted close to a wall or other tank obstruction such as heating coils
and ladders, noise might appear in the measurement signal. See Table 3-1 for
recommended clearance.

For easy access to the transmitter, mount it with sufficient service space (see Table 3-2).

Description Distance

Service space width (A) 20 in. (500 mm)

Service space height (B) 24 in. (600 mm)

3.3.3 Antenna size

Choose as large antenna diameter as possible. A larger antenna diameter concentrates the
radar beam and ensures maximum antenna gain. Increased antenna gain permits greater
margin for weak surface echoes.

In addition, a larger antenna diameter results in a smaller beam angle and thereby, less
interference from any internal structures in the tank.

3.3.4 Antenna inclination

Ensure the antenna is aligned perpendicular to the product surface (see Figure 3-4). The
parabolic antenna comes with a swivel connection that adjusts for angled tank roofs.

Note that if the surface echo is weak in solids applications, then a small inclination of the
parabolic antenna toward the surface slope may improve the performance.

3.3.8 Still pipe/chamber installations

(H)

(1)

Installation in still pipe/chamber is recommended for tanks where there are excessive
foaming or turbulence. Still pipe/chamber may also be used to avoid disturbing objects in
the tank.

For more information and installation requirements, refer to the Best Practices for Using
Radar in Still Pipes and Chambers Technical Note.

Still pipe

Consider the following still pipe requirements:

Pipe

• Pipes should be an all-metal material.

• Pipe should have a constant inside diameter.

• The inner surface must be smooth and clear of any rough edges. (Smooth

pipe joints are acceptable, but may reduce accuracy.)

• The end of the pipe must extend beyond the zero level.

Holes

• Maximum hole diameter is 1 in. (25 mm).

• Minimum distance between holes is 6 in. (150 mm).

• Holes should be drilled on one side only and deburred.

• Drill one hole above maximum product surface.

Rosemount 5408 Level Transmitter 29

The transmitter can be isolated from the process by using a valve:

• Use a full-port ball valve.

• Ensure there is no edge between the ball valve and the nozzle or still pipe, the inside

should be smooth.

• Valves can be combined with still pipes.

• The ball valve should have the same inner diameter as the still pipe.

Prerequisites

Note

In high vibration applications, the transmitter housing must be fully engaged into the
sensor module to meet the vibration test specifications. This is achieved by rotating the
transmitter housing clockwise to thread limit.

Procedure

1. Loosen the set screw until the transmitter housing can rotate smoothly.

2.

First, rotate the housing clockwise to the desired location. If the desired location
cannot be achieved due to thread limit, rotate the housing counterclockwise to the
desired location (up to 360° from thread limit).

3. Re-tighten the set screw.
