Recomended probe length for replacing displacer transmitters

The table below helps to define the GWR probe length for the most common displacer transmitters.

Refer to the flange selection guide on the next page.

Eclipse has proven to be the ideal replacement for exist-

ing torque tube transmitters. In numerous applications

around the world, customers have found Eclipse Guided

Wave Radar superior to torque tube transmitters:

•

Cost:

A new Eclipse costs only slightly more than rebuilding

an aging torque tube.

•

Installation:

No field calibration is necessary; it can be configured

in minutes with no level movement. Factory pre-con-

figuration is available.

•

Performance:

Eclipse is not affected by changes in specific gravity or

dielectric.

•

Ease of replacement:

Proprietary flanges are offered so existing chamber/

cages can be used.

In order to match the proper Eclipse transmitter with the

proper external cage, consider the following:

•

Type of application:

Use the applicable GWR probe, see pages 16 to 27.

•

Overfill proof:

“Overfill” occurs when the level rises above the maxi-

mum range of operation. Radar based probes may pro-

vide erroneous output in this zone unless an optimal

design is used. Eclipse GWR overfill probes without

top transition zones (e.g., 7xG, 7xR, 7xD, 7xT) are

always safe to use. In cases where the application

demands a different probe type, other selections can

be considered and the recommended installation pre-

cautions should be followed.

Min cage size:

•

Coaxial type: min 2"

•

Enlarged Coaxial Type: min 3"

•

Twin rod type: min 3"
