An indicator assembly generates a sound when a liquid is flowing through a fill conduit for a storage tank. The assembly has a body with a first connection device for connection with the fill conduit, and has a second connection device for connection to the storage tank. There is a passageway for liquid which extends between the first and second connection devices. An aspirator has an outer opening outside the body which communicates with an inner opening positioned to contact liquid flowing through the passageway from the fill conduit. A sound generator generates a sound with a flow of air therethrough. The sound generator is connected to the outer end of the aspirator so that, when liquid flows through the passageway for liquid, air is drawn through the aspirator from the storage tank, and the sound generator generates sounds.
