Apparatus for filling a battery or other container to a required level from a remote position. The apparatus includes an arm 1 having at one end a filling nozzle containing a level detecting probe 20. The nozzle is engaged with the filling inlet by manipulation of the arm 1 from the remote position. The nozzle 5 is supplied through the arm 1 with distilled water or other liquid under the control of a pressure- responsive flow valve 4. The flow valve 4 is controlled by a controlling pressure, for example compressed air, admitted through a manually-operable valve 16 at the remote end of the arm 1. The probe 20 is connected through the arm 1 to a controlling pressure connection between a normally-open stop valve 18 and the flow valve 16 and also to a valve member in the stop valve 18. When the probe 20 is closed by the liquid having risen to the required liquid level, an increase in pressure closes the valve member of the stop valve 18 and interrupts the transmission of pressure to the flow valve 4 thereby interrupting the flow of liquid to the nozzle 5, despite the manually-operable valve still being held open. <IMAGE> |
