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

August 2017

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.

2.3 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.

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 CA

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.

2.4 Application examples

The Rosemount 3308 Series Transmitter is suited for aggregate (total) level measurements on a wide range of liquids, semi-liquids, and liquid to liquid interfaces.

Moreover, the reliable and accurate guided wave radar technology offers a versatile solution that is virtually unaffected by process conditions such as temperature, pressure, vapor gas mixtures, density,

turbulence, bubbling/boiling, varying dielectric media, pH, and viscosity.

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 CA

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.

PRELIMINARY

Reference Manual

00809-0100-4308, Rev CA

 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 Ta b le 3 -1 , must be maintained.
