THEORY OF OPERATION The Rosemount 3300 Series Radar Transmitter is a smart, two-wire 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.

APPLICATIONS	The Rosemount 3300 Series Radar Transmitter program 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 3300 transmitters suitable for a wide range of
	applications:
Figure 2-2. Application
examples	Boiling conditions with
	vapor and turbulence. For
	these applications the
	Coaxial probe is particularly
	suitable.

Rosemount 3300 Series

SYSTEM	The Rosemount 3300 Series Radar Transmitter is loop-powered which
ARCHITECTURE	means it uses the same two wires for both power supply and output signal.
	The output is a 4-20 mA analog signal superimposed with a digital HART
	signal.
	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 a Field Communicator or a
	PC with the Radar Configuration Tool software. Rosemount 3300 Series
	transmitters are also compatible with the AMS Suite software which also can
	be used for configuration.
	For HART communication a minimum load resistance of 250 Ohm within the
	loop is required.

Dead Zones	The measuring range depends on probe type and properties of the product.
	The Upper Dead Zone is the minimum measurement distance between the
	upper reference point and the product surface. The Upper Dead Zone varies
	between 4 - 20 in. (0.1 and 0.5 m) depending on probe type and product.

At the end of the probe the measuring range is reduced by the Lower Dead Zone. The Lower Dead Zone also varies depending on probe type and product.

Figure 2-5 illustrates how the measuring range is related to the Dead Zones:

PROCESS	The Rosemount 3300 Series has a high sensitivity due to its advanced signal
CHARACTERISTICS	processing and high signal to noise ratio, which makes it able to handle
	various disturbances. However, the following circumstances should be
	considered before mounting the transmitter.
Coating	Coating on the probe should be avoided since the sensitivity of the transmitter
	may be decreased leading to measurement errors. In viscous or sticky
	applications, periodic cleaning may be required.
	For viscous or sticky applications, it is important to choose a suitable probe:

Table 2-3. Probe type guide for different product viscosity

Bridging

Coaxial	Twin Lead	Single Lead
	Maximum viscosity
500 cP	1500 cP	8000 cP(1)(2)
	Coating/Build-up
Coating not recommended	Thin coating allowed, but no	Coating allowed
	bridging

(1)Consult factory if agitation/turbulence and high viscous products.

(2)HTHP and HP single probes should be used with precaution in viscous or crystallizing media. Cooling of high temperature vapor in the upper part of the probe may lead to condensation and deposition that blocks the measurement signal.

Maximum measurement error due to coating is 1-10% depending on probe type, dielectric constant, coating thickness and coating height above product surface.

Heavy coating that results in product bridging across the two probes for twin lead versions, or between the pipe and the inner rod for coaxial probes, will cause erroneous level readings and must be prevented. Single lead probes are preferred in this case. If a Twin Lead probe is required, regular cleaning may be necessary.

Foam	How well the Rosemount 3300 Series Radar Transmitter measures in foamy
	applications depends upon the properties of the foam; light and airy or dense
	and heavy, high or low dielectrics, etc. If the foam is conductive and creamy
	the transmitter will probably measure the surface of the foam. If the foam is
	less conductive the microwaves will probably penetrate the foam and
	measure the liquid surface.
Vapor	In some applications, as ammonia, there is heavy vapor above the product
	surface that will influence the level measurement. The Rosemount 3300
	Series Radar Transmitter can be configured to compensate for the influence
	of vapor.

Interface

Figure 2-6. Interface measurement with a Rosemount 3302 and a Rosemount 3301 (fully immersed probe).

The maximum measuring range differs depending on application according to:

•Disturbing objects close to the probe.

•Media with higher dielectric constant (εr) gives better reflection and allows a longer measuring range.

•A calm surface gives better reflection than a turbulent surface. For a turbulent surface the measuring range might be reduced.

•Surface foam and particles in the tank atmosphere are also circumstances that might affect measuring performance.

•Coating/contamination can reduce the measuring range.

•Disturbing EMC environment in tank.

Rosemount 3302 is the ideal choice for measuring the interface of oil and water, or other liquids with significant dielectric differences. It is also possible to measure interface with a Rosemount 3301 in applications where the probe is fully immersed in the liquid.

BRIDLE

Coaxial, Rigid twin, Flexible twin and Rigid Single lead 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.

Figure 2-7. Reduction of maximum measuring range for Flexible Twin Lead probe

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 (see “Dielectrics” on page 4-21).

•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.

For the flexible twin lead probe, the reduction of maximum measuring range (65 ft/20 m), can be gained from Figure 2-7 on page 2-10.

However, characteristics varies widely between different applications. For other product combinations, consult factory.

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.

VESSEL CHARACTERISTICS

Heating Coils, Agitators

Tank Shape

The Rosemount 3300 Series Radar 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.
