NOTICE

Failure to follow these installation guidelines could result in death or serious injury:

• Only qualified personnel should perform the installation Explosions could result in death or serious injury: Installation of this transmitter in an explosive environment must be in accordance with the

appropriate local, national, and international standards, codes, and practices. Please review the Product Certifications section for any restrictions associated with a safe installation.

• Before connecting a Field Communicator in an explosive atmosphere, ensure the

instruments are installed in accordance with intrinsically safe or non-incendive field wiring practices

Process leaks may cause harm or result in death:

• Do not remove the transmitter while in operation

• Install device prior to process start-up

• Install and tighten process connectors before applying pressure

Electrical shock can result in death or serious injury:

• Avoid contact with the leads and terminals. High voltage that may be present on

leads can cause electrical shock

This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: This device may not cause harmful interference. This device must accept any interference received, including interference that may cause undesired operation. This device must be installed to ensure a minimum antenna separation distance of 20 cm (8 in.) from all persons.

Power Module Considerations

Each Power Module contains two "C" size primary lithium/thionyl chloride batteries. Each battery contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack. Under normal conditions, the battery materials are self-contained and are not reactive as long as the batteries and the pack integrity are maintained. Care should be taken to prevent thermal, electrical or mechanical damage. Contacts should be protected to prevent premature discharge.

Battery hazards remain when cells are discharged. Power modules should be stored in a clean and dry area. For maximum battery life, storage

temperature should not exceed 30° C. The Power Module may be replaced in a hazardous area. The Power Module has surface

resistivity greater than one gigaohm and must be properly installed in the wireless device enclosure. Care must be taken during transportation to and from the point of installation to prevent electrostatic charge build-up.

Shipping considerations for wireless products

The unit was shipped to you without the Power Module installed. Please remove the Power Module prior to shipping the unit.

Each Power Module contains two "C" size primary lithium/thionyl chloride batteries. Primary lithium batteries are regulated in transportation by the U.S. Department of Transportation, and are also covered by IATA (International Air Transport Association), ICAO (International Civil Aviation Organization), and ARD (European Ground Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure compliance with these or any other local requirements. Please consult current regulations and requirements before shipping

THEORY OF OPERATION The Rosemount 3308 Wireless Guided Wave Radar Level Transmitter is a

continuous level transmitter that is based on Time Domain Reflectometry (TDR) principles. Low power nano-second-pulses are guided along a probe immersed in the process media. When a pulse reaches the surface of the material it is measuring, part of the energy is r eflected 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 below).

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. A calm surface gives better reflection than a turbulent surface.

Figure 2-1. Measurement Principle.

APPLICATION EXAMPLES

The Rosemount 3308 transmitter is suited for aggregate (total) level measurements on most liquids, semi-liquids, and liquid/liquid interfaces.

Guided microwave technology offers highest reliability and precision which ensure measurements are virtually unaffected by temperature, pressure, vapor gas mixtures, density, turbulence, bubbling/boiling, low level, varying dielectric media, pH, and viscosity.

Guided wave radar technology in combination with advanced signal processing make the Rosemount 3308 transmitter suitable fo r a wide range of applications.

SYSTEM ARCHITECTURE

Figure 2-2. System architecture.

The Rosemount 3308 transmitter is battery powered with wireless communication which means the unit works completely independent.

By using the optional HART Tri-loop, it is possib le to convert the HAR T signal to up to three additional 4-20 mA analog signals.

With the HART protocol it is possible to use multidrop configuration. In this case communication is restricted to digital since current is fixed to the 4 mA minimum value.

The transmitter can be connected to display Ros em o un t 75 1 Fi eld Signal Indicator or it can be equipped with an integral display.

The transmitter can easily be configured by using the AMS suite software or by using a Field Communicator. A PC with the Radar Configuration Tool software can also be used for configuration.

For HART communication a minimum load resistance o f 250  within the loop is required.

Rosemount 3308

Interface Rosemount 3308 is the ideal choice for measuring the interface of oil and

water, or other liqui ds with significant dielectric differences.

Figure 2-3. Interface measurement with a Rosemount 3308

All probes can be used for measuring interfaces. The coaxial probe is the preferred choice for clean liquids and when the bridle is not fully immersed . In applications with a fully immersed probe, the twin lead probes are recommended for nozzle installations, and the rigid single lead probe is best for bridle mounting.

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.

If interface is to be measured, the following criteria have to be fulfilled:

• The dielectric constant of the upper product must be kn own. The Radar Configuration Tools software has a built-in dielectric constant calculator to assist users in determining the dielectric constant of the upper product.

• The dielectric constant of the upper product must have a lower dielectric constant than the lower product in order to have a distinct reflection.

• The difference between the dielectric constants for the two products must be larger than 10.

• Maximum dielectric constant for the upper product is 10 for the coaxial probe and 5 for twin lead probes.

• The upper product thickness must be larger than 8 inches (0.2 m) for the flexible twin lead probe and 4 inches (0.1 m) for the rigid twin lead and coaxial probes in order to distinguish the echoes of the two liquids.

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), and the maximum measuring range is only limited by the length of the coaxial and rigid twin lead probes.

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.

V E SSEL CHARACTERISTICS

Heating Coils, Agitators The Rosemount 3308 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, it is possible to hang a weight at the probe end (flexible probes only) or fix/guide the probe to the tank bottom.

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 virtually no effect on the measurement performance. The transmitter handles flat or dish-bottom tanks equally well.
