16. Extra Slides for Internal Guidelines

17. Displacer Terminology

18. Chamber Mounting Flanges Vary With Manufacturer
Some manufacturers like Masoneilan use proprietary flanges as instrument connection
For higher pressure (600# or higher) they use standard ANSI or EN flanges
Most other manufacturers use standard ANSI or EN flanges
Tank connection flange are usually standard ANSI or EN flanges and can be different from instrument connections
Tank connections are usually standard flanges
Instrument connection flanges vary with manufacturer

19. Flange Determination Required information:
Displacer gauge manufacturer + type number
Flange outside diameter or circumference and thickness
Number of bolts
Flange face type and rating RF

Tongue/groove
Ring type joint

Refer to tech note displacer replacer

20. Connection Location Refers to Displacer Chamber Style
For most installations:
simply remove electronics and displacer float assembly.
Replace with GWR flange and probe assembly.
For Top to Side and Top to Bottom:
A tailor made solution needs to be used

21. Transmitter Type & Probe Style Selection
Selection is simple and uniform
Use 3300or 5300 with single probe
Exceptions:
All heavy oil applications above 40 bar and or 150ºC: require 5300 transmitter with single probe
All liquefied gas applications above 40 bar: require 5300 transmitter with coax probe
Saturated steam/water at pressures >40 bar require 5300 with single steam probe (DVC)

22. Probe Length Selection
Probe length is longer than the displacer length.
9 to 10 inches (225 to 250mm) is common, but can be more
Probe should extend full length of chamber
Consider type of flushing connection
Consider a centering disk for longer single rigid probes

23. Calculate GWR Probe Length
Calculate probe length from displacer length
Displacer length = measurement span = distance between process connections
Usual displacer lengths :
14” (356 mm)
24” (609 mm)
32” (812 mm)
48” (1219 mm)
60” (1524 mm)
GWR Probe length = displacer length mm
Consider type of flushing connection
Consider a centering disk for longer single rigid probes

25. Probe Style Options
Rigid probes are recommended instead of flexible for chamber installations
Easier to keep centered in chamber
Centering devices are available for end of single lead probe
Coaxial probes can be used for level measurements of clean fluids and low dielectrics (e.g. liquefied hydrocarbon gasses)
Consider flexible single probe with chamber installation weight for taller chambers and when head space is limited
