Warning Installation must be in accordance with local and national
electric codes for the area classifications. ▲
Warning The source housing handle must be in the OFF position during
installation. ▲
Warning Do not reach inside the source housing at any time during
installation. ▲
Warning Use proper lifting procedures during installation to avoid
injury. ▲
The optimum gauge mounting configuration depends on the application;
however, the source head and the detector are typically mounted together
on the opposite sides of a pipe. The following mounting options are
supported for the gauge:
● Dual chain
● Pipe saddle (cradle) mount
● Pipe spool with gauge head pre-installed
The chain mount is the most frequently used mounting configuration, as it
allows the unit to be mounted on a range of pipe sizes using the same
mounting hardware.
Note Moving the gauge to a pipe with a different diameter may require
changing the radiation source size and/or reconfiguring the detector (ion
chamber) electronics. Contact Thermo Fisher for assistance. ▲
In addition to the guidelines listed earlier in this chapter, note the
following when planning gauge head installation.
● Whichever mounting configuration is used, it is important to align the
beam path (the centerline of the source housing) as closely as possible
with the centerline of the detector housing. Be sure to mount the gauge
head securely, since any movement or change in alignment can affect
the gauge’s calibration.
Thermo Fisher Scientific DensityPRO+ Installation Guide 3-7
Installation
The Gauge Head
● For best performance the beam must pass through a representative
cross-section of the process material being measured. The gauge
measures only the material that passes through the beam. Prevent
suspended solids from settling out of the measured area by mounting
the gauge head on a vertical section of pipe.
● For mounting on a horizontal pipe:
● Position the beam path at a 30- to 45-degree angle from vertical.
This position tends to average density variations caused by settling,
while reducing the effect of any trapped gases or solids that
accumulate in the top or bottom of the pipe.
● If the process material is a solution, a light slurry, or a single-phase
liquid that will not separate, the gauge head can be mounted such
that the beam is horizontal.
● If the process material is a slurry, position the gauge head as far as
possible from any elbows, tees, or valves (these tend to separate
suspended solids). Position the beam path in the plane of the upstream
elbow so the measurement includes any uneven distribution caused by
the fitting.
