In April 1996 a subsample was taken by one 400kHz antenna (transceiver ID 0D) in PH2.
In February 1997 four 400kHz antennas (transceiver IDs 02, 04, 06 and 08) were used as "Main" in PH2.
In March 1999 the four "Main" coils were moved to their present site at the SMF (Smolt Monitoring Facility).
In December 1999 the SMF was brought online with with a 3-way rotating SbyC gate and a 2-way rotating sample gate. Also at this time, the 400kHz transceivers were replaced with ISO transceivers. Monitors created at this point were:
- SbyC Separator Gate (transceiver IDs A1, A2, A3 and A4)
- River Exit (transceiver IDs 81 82)
- SbyC East Tank (transceiver IDs E1 and E2)
- SbyC West Tank (transceiver IDs F1 and F2)
- Sample/Sbyc Exit (transceiver IDs 91, 92 and 93).
In March 2001 the Sample Room monitor was added (transceiver IDs 51 and 52).
In March of 2006 the Full Flow monitor was added upstream of the bypass gate (transceiver IDs 01, 02, 03 and 04).
