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.

Explosions could result in death or serious injury.

 Verify that the operating environment of the gauge is consistent with the appropriate hazardous

locations certifications.

 Installation of device in an explosive environment must be in accordance with appropriate local,

national and international standards, codes, and practices.

 Ensure device is installed in accordance with intrinsically safe or non-incendive field practices.

Electrical shock can result in death or serious injury.

 Ground device on non-metallic tanks (e.g. fiberglass tanks) to prevent electrostatic charge build-up.
 Single lead probes are sensitive for strong electromagnetic fields and therefore not suitable for

non-metallic tanks.

 Care must be taken during transportation of power module to prevent electrostatic charge build-up.
 Device must be installed to ensure a minimum antenna separation distance of 8 in. (20 cm) from all

persons.

 Probes covered with plastic and/or with plastic discs may generate an ignition-capable level of

electrostatic charge under certain extreme conditions. Therefore, when the probe is used in a
potentially explosive atmosphere, appropriate measures must be taken to prevent electrostatic
discharge.

Process leaks could result in death or serious injury.

 Only qualified personnel should install the equipment.
 Install transmitter prior to process start-up.
 Install and tighten process connectors before applying pressure.
 Handle the transmitter carefully.
 Do not remove the transmitter while in operation.
 If the process seal is damaged, gas could escape from the tank when removing the transmitter head

from the probe.

Failure to follow safe installation guidelines could result in death or serious injury.

 Verify that the operating environment of the gauge is consistent with the appropriate hazardous

locations certifications.

 Make sure the transmitter is installed by qualified personnel and in accordance with applicable code

of practice.

 Use the equipment only as specified in this manual. Failure to do so may impair the protection

provided by the equipment.

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).

Transmitter Overview

October 2016

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

Reference Manual

00809-0100-4308, Rev BB

The Upper Reference Point is located at the underside of the transmitter flange or the bottom end of the
threaded adapter, as illustrated in Figure 2-2 on page 4.

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 2-3 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 113.

Note

Measurements may not be possible in the Blind Zones, and measurements close to the Blind Zones will
have reduced accuracy. Therefore, the alarm points should be configured outside these zones.

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 2-4. Multiple communication paths are managed and analyzed in parallel to assure optimal

communication and sustained network reliability even if obstructions are introduced.

Figure 2-4. Emerson Wireless Network

™

Gateways interface with existing host systems using industry standard protocols, and native integration
into DeltaV

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.

™

and Ovation is transparent and seamless.

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 2-5. Interface Level Measurement

Transmitter Overview

October 2016

Tra nsm itter Overv iew

A. Product Level C. Interface 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 109 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 BB

A. Inlet pipe C. Heating coils
B. Agitator

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 30 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 30 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.

00809-0100-4308, Rev BB

 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.

3.4.2 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 160.

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 113 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 Figure3-21. The ground
screw is identified by a ground symbol:

Figure 3-21. Ground Screw

the actual tank height and the configured value.

Non-metallic (e.g. plastic) vessels and installation geometry may introduce an offset for the Upper
Reference Point. This offset may be up to ± 2 in. (50 mm). The offset can be compensated for using
Calibration Offset.

Note

Before running Verify Level, make sure the product surface is calm, the tank is not being filled or
emptied, and the actual level is well above the probe end.

page 101.

 There are rapid level changes in the tank. Select a faster Update

Rate, refer to “Configure Update Rate” on page 60.

 Thin oil layer on top of water that is sometimes detected,

sometimes not. Set the Peak Detection Method to Threshold
Intersection to improve the stability of level measurements in
such applications. Refer to “Resolving thin oil layers” on page 95.

6.3.2 Incorrect or missing interface level reading

Symptom Possible cause and recommended actions

Incorrect Interface Level reading.

Missing Interface Level reading (reported
as NaN).

There are two products in the tank, but
only the product surface or interface is
detected.

There are two products in the tank, but
no readings are reported.

There is only oil in the tank but the
transmitter reports water.

There is only water in the tank but the
transmitter reports oil.

 The Upper Product Dielectric Constant is not correct, see “Upper

Product Dielectric Constant” on page 161.

 Air gap is too big when the Measurement Mode is set to Interface

Level with Submerged Probe. Reduce air gap or switch the
Measurement Mode to Product Level and Interface Level.

 The Measurement Mode is set to Product Level. Set Measurement

Mode to Product Level and Interface Level, refer to “Measurement

Mode” on page 161.

 The Interface Peak is difficult to detect, because the bottom

product has a low dielectric constant, or the signal is attenuated in
the upper product. Check Thresholds. For more information, see

“Example 2: Interface Peak not found” on page 92.

 The upper produc t is too thin to be detected. No action is needed.

See “Interface measurements” on page 109 for minimum
interface thickness for different probe types.

 Check Thresholds, see “Adjusting thresholds” on page 89.
 Check Thresholds, see “Adjusting thresholds” on page 89.

 Check Thresholds, see “Adjusting thresholds” on page 89.
 Make sure the Typical Interface Condition is set to Layer at the

bottom (thin) if you typically have a thin layer at the bottom, see

“Typical Interface Condition” on page 162.

 Check Thresholds, see “Adjusting thresholds” on page 89.
 Make sure the Typical Interface Condition is set to Layer on Top

(Thin) if you typically have a thin layer at the top, see “Typical

Interface Condition” on page 162.
