Introduction

Measurement principle

The Rosemount 5408 and 5408:SIS are two-wire non-contacting radar transmitters for continuous level measurement of liquids, slurries, and solids. The measurement principle is fast-sweep Frequency Modulated Continuous Wave (FMCW).

Radar signals are continuously transmitted towards the product surface with a microwave frequency modulated over a span. The level is proportional to the frequency difference between currently received and transmitted signal.

Technology to redefine reliability

The Rosemount 5408 and 5408:SIS are optimized for reliable and accurate performance even in challenging process conditions. FMCW technology maximizes radar signal strength and produces a robust and reliable measurement (with 30 times more power on the surface than traditional two-wire non-contacting radars).

The transmitters can operate with only 12 Vdc lift-off voltage and they are self-powered for up to 2 seconds to maintain operation despite cable glitches or lightning.

Ease-of-use at every touch point

The Rosemount 5408 and 5408:SIS are designed to simplify operator tasks. They deliver ease-of-use at every touch point, from the pictorial user instructions and graphical, intuitive wizards to the PTFE seal that requires no O-ring material for simplifying model selection.

Dedicated to safety

The Smart Diagnostics Suite provides operators with early alerts in case of antenna build-up, weak power supply, or abnormal surface conditions. Also, a local memory enables full insight into the last seven days of measurements, alerts, and echo profiles.

The Rosemount 5408:SIS is the ideal choice for functional safety such as overfill prevention. It is safety certified (SIL 2/SIL 3), supports long proof-test intervals guaranteed to suit your schedule, and can be tested remotely without any process interruption.

Application examples

The Rosemount 5408 and 5408:SIS are 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. Furthermore, non-contacting radar level is ideal 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 Blenders and mixers

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

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.

Open atmospheric applications Still pipe and chamber installations

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

The Rosemount 5408 is an excellent choice for level measurement in tanks with still pipes. It may also be used in chambers, but guided wave radar is generally the best fit for these applications.

Bulk solids Safety applications

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.

The Rosemount 5408:SIS is the ideal choice for safety functions such as overfill prevention, level deviation monitoring or dry-run prevention.

Conditions used for flange strength calculations

Air purging

An air purge connection can prevent clogging of the antenna in extreme applications with dirt or heavy coating. The easiest way to determine if air purging is needed, is to inspect the tank internal conditions at the location intended for the transmitter.

If there is normally a thick layer of product build-up there, air purging is most likely needed. Typical purging media to use is air.

All parabolic antennas come with an integrated air purge connection (see Figure 10).

An air purge connection is also available for cone antennas with flanged connection by selecting option code PC1. This option consists of an antenna with purge holes and a separate air purge ring (see Figure 10).

Installation and mounting considerations

Tank installations

For optimal performance, the transmitter should be installed in locations with a clear and unobstructed view of the product surface.

The transmitter should be mounted with as few internal structures as possible within the signal beam, see “Beam angle and beam width” on page 18.

Do not install the transmitter in the center of the tank.

Do not mount close to or above the inlet stream.

Multiple Rosemount 5408 and 5408:SIS Level Transmitters can be used in the same tank without interfering with each other.

Table 18. Distance to Tank Wall (L)

Figure 11. Recommended Mounting Position

Non-metallic tanks

The walls in non-metallic tanks can be invisible to the radar signal, so nearby objects outside the tank may cause disturbing radar echoes. Wherever possible, the transmitter should be positioned so that objects close to the tank are kept outside the signal beam.

Antenna size

Choose as large antenna diameter as possible. A larger antenna diameter concentrates the radar beam, will be less susceptible to obstruction interference, and assures maximum antenna gain.

Antenna inclination

Ensure the antenna is aligned perpendicular to the product surface (see Figure 12). 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.

Figure 12. Inclination

Nozzle requirements for cone antenna

For best measurement performance, the cone antenna should extend at least 0.4 in. (10 mm) below the nozzle. If required, use the extended cone antenna versions (option code S1 or S2).

Still pipe/chamber installations

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. 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.

Antenna:

All cone/process seal antenna sizes can be used for still pipe/chamber installations.

The gap between the cone antenna and the still pipe should be maximum 0.2 in. (5 mm). If required, order a larger antenna and cut on location. See Figure 17 on page 38 for antenna dimensions.

For more information, refer to the Guidelines for Choosing and Installing Radar in Stilling Wells and Bypass Chambers Technical Note.

Ball-valve installations

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.

Nozzle size (D) Inclination angle (α)

Maximum nozzle height (H)(1)

1. Note that the inside of the nozzle must be smooth (i.e. avoid bad welding, rust, or deposit).
