HYDRAULIC FLUID QUANTITY INDICATING - DESCRIPTION AND OPERATION
_______________________________________________________________
1. General
_______
The hydraulic quantity indicating system has two functions. They are
-
to show the fluid contents of each reservoir for the flight crew and
maintenance personnel,
-
to send signals to the Electronic Centralized Aircraft Monitor (ECAM) system and the overhead panel when the contents of any reservoir is less than a specified minimum.

3. System Description
__________________
Each reservoir has a gage-transmitter which gives a visual indication and sends electrical signals to show the fluid contents. The unit is a float assembly connected mechanically to a synchro transmitter. The pointer of the mechanical contents gage is connected to the synchro transmitter. When the float moves, the synchro transmitter and the pointer turn together. The synchro transmitter sends signals to the ECAM system and to the reservoir quantity indicator on the Green ground-service panel.
A reservoir quantity indicator is installed on the Green ground-service panel. It operates together with the filling selector valve and shows the contents of the reservoir which the selector valve is set to.
