AquaMaster 3 FET200
Electromagnetic flowmeter Transmitter 3 Electrical Installation
OI/FET200–EN Rev. I 25
3.5 Power Supply Connections
AquaMaster3 has 4 power supply options:
Internal batteries (integral transmitters only) – see Section 3.5.1 (following)
External battery pack – see Section 3.5.2, page 27
Mains power – see Section 3.5.3, page 27
Renewable energy – see Section 3.5.4, page 28
3.5.1 Fitting / Replacing Internal Batteries (Integral Transmitters Only)
Referring to Fig. 3.17:
1. Remove enclosure lid
A.
2. Remove and discard silica gel bag.
3. Disconnect battery connector
B.
4. Carefully remove battery pack
C from enclosure.
5. Carefully remove 3 cells
D in turn from the top level of the pack.
6. Carefully remove 3 cells
E in turn from the bottom level of the pack.
7. Fit 3 new cells to the bottom level of the pack, ensuring the correct polarity, as shown in Fig. 3.17,
page 26.
8. Fit 3 new cells to the top level of the pack.
9. Carefully refit battery pack
C to enclosure.
10. Reconnect battery connector
B.
11. Place new silica gel bag on top of battery pack.
12. Ensuring O-ring seal and O-ring groove is clean, refit enclosure lid
A and tighten finger-tight.
Warning.
Disconnect the supply from any cables being terminated on the transmitter.
Electrical installation and earthing (grounding) must be in accordance with relevant national and
local standards.
Note. Power supply connections / earthing arrangements are identical for cathodically-protected
remote transmitter systems. For cathodically-protected integral transmitter systems, follow cathodic
installation practices.
Caution.
Never remove lid when water level around the flowmeter is close to enclosure lid.
Use 3.6 V Lithium cells only
Ensure correct polarity (all cells must face upwards)
Do not mix old and new cells
Use cells from a single manufacturer
Use only batteries of the correct type, as listed in Appendix B.1, page 40.
