Replacing the Flow Sensor
To replace the Flow Sensor (Figure 3-6):
1. Open the analyzer and electronics enclosure door and expose the analyzer
components and electronics.
2. Close the isolations valves on the inlet and outlet of the process. Shutoff
levers should be in the vertical position.
3. Disconnect the RTD flow sensor wires from the
Sensor
board at Terminal
Cact
.
4. Disconnect the RTD flow sensor from the J-hook by unscrewing the
Swagelok nut indicated in the image below.
5. Install the new RTD flow sensor into the J-hook. Make sure to properly
swage the nut to avoid any leaks.
6. Route the wires through the top conduit back to the electronics enclosure.
7. Connect the new wires to the
Cact
terminals.
8. Reopen the process valves and close the enclosure doors.
