Intek RheoVac 950A - Manual (Page 7)

SECTION 2 — INSTALLATION
These instructions are general guidelines for the installation of RheoVac instruments in their
standard configuration. Additional information pertaining to your unit is covered in SECTION 6
— CUSTOM INFORMATION. Carefully read these instructions prior to installing the equip-
ment. Also, see preceding SECTION 1.5; PRECAUTIONS AND RECOMMENDATIONS.
2.1 RheoVac SYSTEM INSTALLATION/SITE SELECTION
The standard RheoVac 950 can be configured with one, two or three probes. A three probe
system is intended to be installed so that one probe is in each of the two exhaust lines coming out
of the condenser (A side and B side). The third probe should go in the header pipe that runs to
the exhauster(s). Other installation arrangements of multiple probes should be discussed with the
factory. High temperature dual probe systems (where each “probe” is comprised of a matched
main FTP probe and an RS probe pair) have different configuration limitations for a given
RheoVac 950 system.
2.1.1 Probe Site Selection
x The location for each probe should be selected so as to provide the probe sensing area
with well-established mean flow velocity, uniform system temperature and pressure, and
consistent non-liquid phase flow medium. Pipe sections ahead of a probe, in which water
can accumulate, must be avoided. Refer to Figure 2 and select the most preferred
location for each probe. Do not install the probes beyond any “trap” sections as shown in
Figure 2, Configurations B and D. Special installation instructions unique to your unit,
where applicable, will be noted in SECTION 6.3 SPECIAL INSTRUCTIONS. Refer to
this section now to review special instructions.
