ABSTRACT OF THE INVENTION A liquid concentrate dispensing apparatus having a removable and refillable concentrate tank with sensors connected therewith flush with the inside wall of the tank to facilitate cleaning. The sensors comprise detectors which include an electrically conductive housing, and one wall of the housing is substantially flush with the inside wall of the tank. Spring biased detent members on the outside of the tank releasably connect the detectors with the dispensing apparatus when the tank is inserted to a preselected position. The tank is provided with two such sensors, one is located in the sidewall and the other is located in the bottom wall. When the tank is inserted into the dispensing apparatus, the spring biased detent members engage contacts on the apparatus. A current passes between the detectors on the sidewall and bottom wall when both are covered by liquid concentrate. When concentrate no longer covers the detector in the sidewall, the current doesn't pass, thus indicating that concentrate needs to be added to the tank.
