6.3 Upgrading from the FGM 130
It is strongly recommended to upgrade all FGM 130 installations to FGM 160. The upgrade is
relatively simple and easy to perform. Existing mounts can be used, although the transducers
must be replaced, as the FGM 160 uses upgraded Ultrasonic Transducers, and the signal is
not backward compatible with the Ultrasonic Transducers used with the FGM 130. The
existing temperature and pressure sensors can be used, and the fiber optic cables can be re-
used for DCS signal transmission with the addition of an RS485 optical converter. The figure
below shows the similarities and differences between the FGM 130 and FGM 160 setups.
