2.1 Theory of operation

The Rosemount™ 3308 Series is the first true wireless level transmitter that is based on the Time Domain Reflectometry (TDR) principle. Low power nano-second-pulses are guided along a probe submerged in the process media. When a pulse reaches the surface of the material it is measuring, part of the energy is reflected back to the transmitter, and the time difference between the generated and reflected pulse is converted into a distance from which the total level or interface level is calculated (see Figure 2-1). See

Figure 2-2 for a schematic overview of the signal processing.

Transmitter Overview

January 2018

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

Reference peak

This peak is caused by the transition between transmitter and the tank vapor space or air. It is used by the transmitter as a starting reference point for distance to the level surface.

Product surface peak

This peak indicates the product level and is caused by a reflection from the product surface.

Interface peak

This peak indicates the interface level. The peak is caused by reflection from the interface between an upper product and a bottom product with a relatively high dielectric constant. This peak is identified when the Measurement Mode is set to Product Level and Interface Level or Interface Level with Submerged Probe.

Probe end peak

It is caused by reflection from the probe end. If the probe is grounded, the peak will be positive. If the probe end is submerged in a high dielectric media, such as water, it will not be visible.

Upper reference point

The Upper Reference Point is located at the underside of the threaded adapter, transmitter flange, or Tri Clamp, as illustrated in Figure 2-3 on page 5.

Transmitter Overview

Zero reference point

The Zero Reference Point is selected by the user and is usually located close to or at the bottom of the tank. The Zero Reference Point can be set to any position in the tank by adjusting the Tank Height.

Tank height

The Tank Height is the distance from the Upper Reference Point to the Zero Reference Point. The transmitter measures the distance to the product surface and subtracts this value from the Tank Height to determine the level.

Probe length

The probe length is the distance between the Upper Reference Point and the end of the probe. If a weight is used at the end of the probe it shall be included.

Blind zones

The measuring range depends on probe type, dielectric constant of the product and installation environment, and is limited by the Blind Zones at the very top and bottom of the probe. In the Blind Zones, the accuracy exceeds ±1.18 in. (30 mm), and measurements may not be possible. Measurements close to the Blind Zones will have reduced accuracy.

Figure 2-4 illustrates how the measuring range is related to the Blind Zones and the areas with reduced

accuracy. Values for different probe types and dielectric constants are presented in section “Ac cu ra cy

over measuring range” on page 114.

2.2 Wireless by Emerson

The Emerson Wireless network is a self-organizing solution. Wireless field instruments send data to a Gateway, directly or routed through any of the wireless devices in the network, as illustrated in

Figure 2-5. Multiple communication paths are managed and analyzed in parallel to assure optimal

communication and sustained network reliability even if obstructions are introduced.

2.3 Application characteristics

2.3.1 Tank shape

The guided wave radar transmitter is insensitive to the tank shape. Since the radar signal travels along a probe, the shape of the tank bottom has no effect on the measurement performance. The transmitter handles flat or dish-bottom tanks equally well.

Transmitter Overview

January 2018

2.3.2 In-tank obstructions

The Rosemount 3308 Series Transmitter is relatively insensitive to objects in the tank since the radar signal is transmitted along a probe.

Avoid physical contact between probes and agitators as well as applications with strong fluid movement unless the probe is anchored. If the probe can move within 1 ft. (30 cm) away from any object, such as an agitator, during operation then probe tie-down is recommended.

In order to stabilize the probe for side forces, you have the option to either hang a weight at the probe end (flexible probes only) or fix/guide the probe to the tank bottom.

2.3.3 Interface level measurement

Rosemount 3308 Series Transmitter is well suited for measuring the interface of oil and water, or other liquids with significant dielectric differences.

Figure 2-6. Interface Level Measurement

Reference Manual

00809-0100-4308, Rev CB

A. Product Level B. Interface Level

All probes can be used for measuring interfaces. Single probes are the preferred choice in almost all applications but depending on the application and installation geometries a coaxial probe or a flexible twin probe may be a better fit.

For measuring the interface level, the transmitter uses the residual wave of the first reflection. Part of the wave, which was not reflected at the upper product surface, continues until it is reflected at the lower product surface. The speed of this wave depends fully on the dielectric constant of the upper product.

The maximum allowable upper product thickness/measuring range is primarily determined by the dielectric constants of the two liquids. Target applications include interfaces between oil/oil-like and water/water-like liquids. For such applications the upper product dielectric constant is low (<3) and the lower product dielectric constant is high (>20). Refer to “Interface measurements” on page 119 for further interface application guidelines.

Emulsion layers

Sometimes there is an emulsion layer (mix of the products) between the two products which, depending on its characteristics, will affect interface measurements. Please consult factory for guidelines on how to handle emulsion layers.

3.3 Review mounting considerations

Before installing the Rosemount 3308 Series Transmitter, consider recommendations for sufficient free space, mounting position and special needs for non-metallic tanks.

3.3.1 Recommended mounting position

When finding an appropriate mounting position for the transmitter, the conditions of the tank must be carefully considered. The transmitter should be mounted so that the influence of disturbing objects is reduced to a minimum. For easy access to the transmitter make sure that it is mounted with sufficient service space.

Figure 3-1. Mounting Position

Reference Manual

00809-0100-4308, Rev CB

A. Inlet pipe B. Agitator C. Heating coils

The following guidelines should be considered when mounting the transmitter:

 Do not mount close to inlet pipes.  Do not mount close to agitators. If the probe can move to within 12 in. (30 cm) away from an agitator,

the probe should be anchored. See “Anchor the probe” on page 33 for more information.

 If the probe tends to sway due to turbulent conditions in the tank, the probe should be anchored. See

“Anchor the probe” on page 33 for more information.

 Avoid mounting close to heating coils.  Position the probe such that it is subject to a minimum of lateral force.  Make sure the probe does not come into contact with the nozzle or other objects in the tank.

Installation

Page 29

Reference Manual

00809-0100-4308, Rev CB

 Make sure the nozzle does not extend into the tank.

Note

Violent fluid movements causing high sideway forces may break rigid probes.

If the probe is mounted close to a wall, nozzle or other tank obstruction, noise might appear in the level signal. Therefore the following minimum clearance, according to Tab l e 3 - 1, must be maintained.

3.3.4 Installation in still pipe/chamber

General chamber considerations

A chamber or pipe installation is the preferred option due to the increase in stability and performance of the transmitter. When selecting a smaller diameter chamber or pipe (such as 2-in.) a flexible probe is not suitable due to the chance of it coming into contact with the walls, and relatively large side inlets may interfere with the signal.

When gas lift and/or turbulence may occur (e.g. boiling hydrocarbons), a 3- or 4-in. chamber/pipe diameter is recommended for maximum measurement reliability. This is especially true in high pressure and high temperature installations.

Rosemount 9901 Chamber

Rosemount 9901 allows external mounting of process level instrumentation. It supports a variety of process connections, and optional drain and vent connections. The Rosemount 9901 chamber is designed to the ASME B31.3 standard, and is Pressure Equipment Directive (PED) compliant. Use option code XC to order together with the Rosemount 3308 Series Transmitters.

Figure 3-7. Side-and-Side and Side-and-Bottom Chambers

Reference Manual

00809-0100-4308, Rev CB

The probe length to use for a Rosemount 9901 chamber can be calculated with this formula:

Side-and-side dimension:

Probe length=Centre-to-centre dimension + 19 in. (48 cm)

Side-and-bottom dimension:

Probe length=Centre-to-centre dimension + 4 in. (10 cm)

Use a centering disc the same diameter as the chamber if the probe length >3.3 ft. (1 m). See Table 3- 5

on page 28 for which disc to use.

For additional information, see the Rosemount 9901 Chamber for Process Level Instrumentation Product

Data Sheet.

Considerations when changing to Rosemount 3308 Series:

 The 3308 Series flange choice and probe length must be correctly matched to the chamber. Both

standard ANSI and EN (DIN), as well as proprietary chamber flanges, are available. See Table A-19 on

page 146 to identify the proprietary flanges.

 See Table 3-5 on page 28 for guidelines on which disc size to use.  See Tab l e 3 - 3 for guidelines on the required probe length.

Probe type in chamber considerations

Installation

When installing a Rosemount 3308 in a chamber, the single lead probe is recommended. The probe length determines if a single rigid or single flexible probe should be used:

 Less than 19.7 ft. (6.0 m): Rigid single probe is recommended. Use a centering disc for probe > 3.3 ft.

(1 m). When mounting space is limited, use a flexible single probe with a weight and centering disc.

 More than 19.7 ft. (6.0 m): Use flexible single probe with a weight and centering disc.

PTFE covered probes are not recommended for chamber/pipe installations.

3.4.2 Shorten the probe

In order to leave some clearance distance between the probe end and the tank bottom, the probe might have to be shortened. The goal is to have the probe hang straight so that it does not touch the wall. 2 in. (5 cm) is a suggested value. The probe can be shortened in field. Use the following form to calculate the probe length:

Probe Length = Tank height - 2 in. (5 cm)

After shortening the probe make sure to update the transmitter configuration to the new probe length, see “Probe length” on page 162.

3.5 Anchor the probe

In turbulent tanks it may be necessary to fix the probe. Depending on the probe type, different methods can be used to guide the probe to the tank bottom. This may be needed in order to prevent the probe from hitting the tank wall or other objects in the tank, as well as preventing a probe from breaking.

3.5.1 Flexible single/twin lead probe

The flexible single lead probe itself can be used for anchoring. Pull the probe rope through a suitable anchoring point, e.g. a welded eye, and fasten it with a chuck.

The length of the loop will add to the Blind Zone. The location of the chuck will determine the beginning of the Blind Zone. See “Accuracy over measuring range” on page 114 for further information on Blind Zones.

The Probe Length should be configured as the distance from the Upper Reference Point to the top of the chuck.

3.7 Ground the device

The Rosemount 3308 Series Wireless Guided Wave Radar transmitter operates with the housing grounded or floating. Floating systems can cause extra noise that may affect many types of readout devices. If the signal appears noisy or erratic, grounding at a single point may solve the problem.

Grounding of the electronics enclosure should be done in accordance with local and national installation codes. Grounding is accomplished by using the external case grounding terminal.

Non-metallic tanks

Ground device on non-metallic tanks (e.g. fiberglass tanks) to prevent electrostatic charge build-up.

There is one grounding screw connection provided, located on the housing, see Figure 3-19. The ground screw is identified by a ground symbol:

Figure 3-19. Ground Screw

Reference Manual

00809-0100-4308, Rev CB
