Guided wave radar

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 left).

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.

Thanks to innovative technologies, inherited from market leading Rosemount guided wave radars 3300 and 5300 Series,

Rosemount 3308 Series enables reliable measurements combined with long battery life.

Emerson Smart Wireless

Emerson Smart Wireless is a self-organizing network solution.

Wireless field instruments send data to a Gateway, directly or routed through any of the wireless devices in the network.

Multiple communication paths are managed and analyzed in parallel to assure optimal communication and sustained network reliability even if obstructions are introduced.

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.

The Rosemount 3308 Series joins the Emerson Wireless portfolio, whose wireless network experience totals billions of operating hours, hundreds of thousands field devices, and tens of thousands of networks around the world.

Interface measurements

Rosemount 3308 Series

The Rosemount 3308 Series is well suited for interface measurements, including applications where the probe is fully submerged in the liquid:

Considerations

Interface Level

Product Level

Interface Level

Interface Measurement Interface Measurement with fully submerged probe

If interface is to be measured, follow these criteria:

 The dielectric constant of the upper product must be known and should not vary. The AMS

Wireless Configurator and Field Communicator have a built-in dielectric constant calculator to assist the user 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 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 5.

 Minimum detectable upper product thickness is 4 in. (10 cm).

For guidelines on emulsion situations, consult your local Emerson Process Management representative.

Interface measuring range

Considerations

Rosemount 3308 Series

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, with a low (<3) dielectric constant for the upper product and a high (>20) dielectric constant for the lower product. For such applications, the maximum measuring range is limited by the length of the coaxial and rigid single lead probes.

For flexible probes, the maximum measuring range is reduced by the maximum upper product thickness, according to the diagram below. However, characteristics may vary between the different applications.

Accuracy over measuring range

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.

The following conditions will impact the Blind Zones:

 If the single lead probes or twin probes are installed in a nozzle, the nozzle height shall be added to the specified

Upper Blind Zone.

 The measuring range for the PTFE covered Flexible Single Lead probe includes the weight when measuring on a high dielectric media.

 When using a metallic centering disc, the Lower Blind Zone is

8 in. (20 cm), including weight if applicable. When using a

PTFE centering disc, the Lower Blind Zone is not affected.

Other Mechanical Considerations

Weight

Make sure the nozzle does not extend into the tank.

To get best possible performance, the following must be considered before installing the transmitter:

 Inlets should be kept at a distance in order to avoid product filling on the probe.

 Avoid physical contact between probes and agitators, as well as applications with strong fluid movement unless the probe is anchored.

 Probe tie-down is recommended if the probe can move to within 1 ft. (30 cm) of any object during operations.

 In order to stabilize the probe for side forces, it is possible to fix or guide the probe to the tank bottom

Flexible single lead probe with chuck.

 Single lead probes are not suited for non-metallic tanks or open atmosphere applications, due to high susceptibility to strong electromagnetic fields.

Engineered solutions

Pxxx

When standard model codes are not sufficient to fulfill requirements, please consult the factory to explore possible Engineered Solutions. This is typically, but not exclusively, related to the choice of wetted materials or the design of a process connection. These Engineered

Solutions are part of the expanded offerings and may be subject to additional delivery lead time. For ordering, factory will supply a special P-labeled numeric option code that should be added at the end of the standard model string. See example model string below.

Example Model String:

Chamber / pipe installations

General Chamber Considerations

Rosemount 9901 Chamber

Existing Chamber

The recommended minimum chamber diameter is 4 in. (100 mm) for Single Flexible probe and 3 in. (75 mm) for the Single Rigid probe. The probe should be centered to prevent it touching the sides of the well.

PTFE covered probes are not recommended for chamber/pipe installations.

Rosemount 9901 allows external mounting of process level instrumentation. It supports a variety of process connections, and optional drain and vent connections. The Rosemount 9901 chamber is designed to the ASME B31.3 standard, and is

Pressure Equipment Directive (PED) compliant. Use option code XC to order together with the 3308

Series transmitters.

The probe length to use for a Rosemount 9901 chamber can be calculated with this formula:

Side-and-side dimension

Side-and-bottom dimension

Side-and-side dimension:

Probe length=Centre-to-centre dimension + 19 in.

(48 cm)

Side-and-bottom dimension:

Probe length=Centre-to-centre dimension + 4 in.

(10 cm)

Use a centering disc the same diameter as the chamber if the probe length >3.3 ft. (1 m). See

“Centering Discs” on page 24

for which disc to use.

For additional information, see the Rosemount 9901 Chamber for Process Level

Instrumentation Product Data Sheet (document number 00813-0100-4601).

A Rosemount 3308 Series transmitter is the perfect replacement in an existing displacer chamber.

Proprietary flanges are offered, enabling use of existing chambers to make installation easy.

Considerations when changing to 3308 Series:

 The 3308 Series flange choice and probe length must be correctly matched to the chamber. Both standard ANSI and EN (DIN), as well as proprietary chamber flanges, are available. See

“Proprietary

Flanges” on page 35

to identify the proprietary flanges.

Rosemount 3308 Series July 2014

Probe Type in Chamber

Considerations

Centering Discs

When installing a Rosemount 3308 in a chamber, the single lead probe is recommended. The probe length determines if a Single Rigid or Single Flexible probe should be used:

 Less than 19.7 ft. (6.0 m):

Rigid Single Probe is recommended. Use a centering disc for probe > 3.3 ft. (1 m). When mounting space is limited, use a Flexible Single Probe with a weight and centering disc.

 More than 19.7 ft. (6.0 m):

Use Flexible Single Probe with a weight and centering disc.

To prevent the probe from contacting the chamber or pipe wall, centering discs are available for rigid single, flexible single, and flexible twin lead probes. The disc is attached to the end of the probe. Discs are made of stainless steel or

PTFE. See Table 9 on page 25 for Dimension D. Table 10 on page 25

shows which centering disc diameter to choose for a particular pipe.
