Mounting
Considerations
1. Mounting bands should be inspected periodically and retightened if
necessary. Some loosening may occur after initial installation due to
thermal expansion/contraction.
2. The waveguide must be in direct contact with the pipe.
3. Insulate process piping to minimize ambient temperature effects (see
Figure 3-4). Insulation thickness over the top of the waveguide foot
should not exceed 2.54 cm (1-in).
4. For best results, mount the transmitter within 15.24 cm (6 in.) of the
equipment to be monitored.
5. The stainless steel mounting bands could be affected by stress
corrosion and potentially fail when in the presence of chlorides.
6. The transmitter should be installed 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, the device should be installed
on the upstream side of the trap.
