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 (charged or discharged) are regulated during transportation by the U.S. Department of
Transportation. They 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. Consult current regulations and requirements before shipping.

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.
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.

Figure 2-3. Upper Reference Point
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 “Accuracy
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.
Figure 2-5. Emerson Wireless Network
Gateways interface with existing host systems using industry standard protocols, and native integration
into DeltaV™and Ovation™is transparent and seamless.
Interference from other radios, WiFi, and EMC sources is avoided through Time Synchronized Channel
Hopping and Direct Sequence Spread Spectrum (DSSS). Also, a layered security implementing industry
standard Encryption, Authentication, Verification, Anti-Jamming, and Key Management ensures that
data transmissions are secure and received only by the Gateway.
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
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
