the LH(RH) wing tank
-
the center tank.
The tank level sensing system also monitors the temperature of the
fuel in the LH(RH) wing tank.

The system has level sensors that the FLSCUs continuously monitor. The FLSCUs uses signal conditioning to find if the sensor is wet or dry. The FLSCUs use the fuel level data to:
-
control the operation of the intercell transfer system (Ref. 28-15-00)
-
control the operation of the recirculation system (Ref. 28-16-00)
-
control the operation of the main fuel pump system (Ref. 28-21-00)
-transmit fuel level warnings to the Engine/Warning Display (EWD) (Ref. 31-66-00)
-control high level shut-off for automatic and manual refuel (Ref. 28-25-00).

**ON A/C ALL
The tank level sensing system has temperature sensors in the wing tanks. The FLSCU uses signal conditioning to calculate the temperature of the fuel adjacent to the sensor. The FLSCU uses the temperature data from the wing tanks to control the operation of the recirculation system (Ref. 28-16-00).
