There are many types, but primarily a flow alarm works by a pressure switch that indicates a pressure drop when a sprinkler head (or test valve) opens, or an actual in-flow mechanism (a propeller or a movable flap) that moves when water flows.
Some early models (still in existence) run water through an impeller that moves a clapper in a gong while water is flowing.
