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.
NOTICE
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 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 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. |

APPLICATION |
The Rosemount 3308 transmitter is suited for aggregate (total) level |
EXAMPLES |
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 for 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 possible to convert the HART 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 Rosemount 751 Field 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 of 250 within the loop is required.

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 known. 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.

CHARACTERISTICS |

Heating Coils, Agitators
Tank Shape
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.
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.

WIRELESS CONSIDERATIONS
General
The Wireless Guided Wave Radar Transmitter has the capability to measure level, distance, interface level or volume. The Rosemount 3308 converts the measurement data into mapped variables and diagnostic information that are transmitted through a wireless signal.
Power Up Sequence
The Smart Wireless Gateway (Gateway) should be installed and functioning properly before any wireless field devices are powered. Install the Black Power Module, SmartPower™ Solutions model number 701PBKKF into the 3308 transmitter to power the device. Wireless devices should also be powered up in order of proximity from the Gateway, beginning with the closest. This will result in a simpler and faster network installation. Enable Active Advertising on the Gateway to ensure that new devices join the network faster. For more information, see the Gateway Product Manual (Document Number 00809-0200-4420).
Antenna Position
The antenna should be positioned vertically, either straight up or straight down. It should be approximately 3 ft (1 m) from any large structure, building, or conductive surface to allow for clear communication to other devices.
