4.1 general
This instrument must be installed by an expert engineer or skilled personal. The procedures described in this
chapter are not permitted for operators.
For the installation of explosion protected instruments see chapter 9 „Explosion protected type instruments”.
If the detector is not insulated, the surface of detector may be very hot according to the process temperature.
- Keep protection sheet on the flanges attached until the flowmeter is installed to piping.
- Don’t open the terminal box until the wiring procedure. Leaving the box opened can result in insulation
deterioration.
- A newly installed piping-line often contains foreign matters (such as welding scrap and wood chips).
Remove them by flushing the piping before installing the flowmeter. This will help to prevent not only
damaging the flowmeter, but making erroneous signal generated by foreign matters.
- For RCCT3 or RCCF31 at ambient temperature above 50°C a sunshade is recommended. This is
particularly important in countries with high ambient temperatures.
About the site
To stabilize the instrument, please consider the following items where to place the instrument for your long-term
use.
- Ambient Temperature
Please avoid installing in a place which has a large temperature gradient and variation as possible. And if
the meter is subjected to radiant heat from plant, please use heat insulation measure or please set up so
that is well ventilated.
- Atmospheric conditions
Please avoid to place in a corrosive atmosphere as possible. When used in corrosive atmosphere, allow
better ventilation.
- Shock and vibration
Please install in a place without shock and vibration as possible.

Explosion-proof equipment installations
If the product is installed in hazardous areas please notice the installation hints in chapter 9.
Sequence of installation:
- Mounting of detector RCCS30 to 33 on a 2-inch pipe if option /PD was ordered (see chapter 4.2)
- Piping of the detector or integral flowmeter in the line (see chapter 4.3)
- Customer insulation of detector if necessary (see chapter 4.4)
- Mounting of converter RCCF31 on a 2-inch pipe (see chapter 4.5)
- Mounting of converter RCCR31 in a subrack (see chapter 4.6)
- Alteration of converter display of converter RCCF31 if necessary (see chapter 4.7)
- Wiring of converter (see chapter 4.8)
- After installation an autozero according chapter 5.6 must be executed. When carrying out the zero-
adjustment, the measuring tube should be filled with the liquid at “no flow”. It is therefore recommended
to have shut-off valves at appropriate points of the upstream (vertical installation) and downstream
(horizontal installation) of the flowmeter.
