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.
