2.1.6 Mounting installation considerations
Procedure
1. Inspect mounting bands periodically and re-tighten if
necessary.
Some loosening may occur after initial installation due to
thermal expansion/contraction.
2. Ensure the waveguide is in direct contact with the pipe.
3. Insulate process piping to minimize ambient temperature
effects (see
Insulation thickness over the top of the waveguide foot should
not exceed 1 in. (2.54 cm).
4. For best results, mount the transmitter within 6 in. (15.24 cm)
of the equipment being monitored.
5. The stainless steel mounting bands could be affected by
stress corrosion and potentially fail when in the presence of
chlorides.
6. Install the transmitter such that steam or other high
temperature fluids do not directly impinge the housing of the
device.
7. If installing the device on a steam trap, install the device on
the upstream side of the trap.
2.2 Mount the transmitter
For high temperature mounting, see
temperature
Procedure
1. Locate the Rosemount 708 Transmitter on a horizontal section
of piping as close as possible to the equipment to be
monitored. Align the waveguide of the transmitter as shown
in
2. Ensure the mounting location is free of foreign matter and
corrosion to ensure good contact between the piping and
waveguide.
3. Tighten each clamp to 90 in.-lb. (10.2 N-m). Trim the excess
clamp band material to prevent unwanted acoustic noise.
4. If commissioning the device, install the power module (see
Power
5. Ensure the power module cover is fully tightened to prevent
moisture ingress.
