A beverage maker device, comprising: a housing installable in an aircraft galley; a tank configured to hold a volume of a fluid, the tank coupled to a fluid supply via an inlet coupling; and a manifold disposed within the housing and including one or more solenoid valves configured to control dispensing of the fluid from the tank through an outlet; and an inlet body operatively coupled to the inlet coupling and to the tank, the inlet body comprising: a restriction orifice configured to restrict a flow of the fluid; a tank-side pressure transducer disposed between the restriction orifice and the tank, the tank-side pressure transducer configured to 1) sense at least one tank-side flow pressure associated with the flow of the fluid and 2) generate at least one tank-side flow signal corresponding to the tank-side flow pressure; and a coupling-side pressure transducer disposed between the restriction orifice and the inlet coupling, the coupling-side pressure transducer configured to 1) sense at least one coupling-side flow pressure associated with the flow of the fluid and 2) generate at least one coupling-side flow signal corresponding to the coupling-side flow pressure; and a process control board, PCB, disposed within the housing, the PCB comprising: at least one control processor; control circuitry communicatively coupled to the control processor, to the solenoid valves, to the tank-side pressure transducer, and to the coupling-side pressure transducer, the control circuitry configured to: receive the at least one coupling-side flow signal and the at least one tank-side flow signal; and based on the coupling-side flow signal and the tank-side flow signal, determine at least one differential pressure associated with the flow of the fluid; and wherein the control circuitry is configured to direct the solenoid valves to adjust the dispensing of the fluid based on the determined differential pressure. a housing installable in an aircraft galley;
