ABSTRACT:
A liquid chemical measuring system including an elongate translucent or transparent polymeric tank having an upper portion with graduations indicating the amount of liquid required to fill the tank to each of the graduations when said tank is vertically disposed, and a generally funnel shaped portion adjacent its lower end. The tank has a liquid passage opening through its lower end, and an air passage through a transverse wall at its upper end. A frame supports the tank with its upper end uppermost, a liquid valve is attached to the tank across its liquid passage opening, and an air pump is coupled to the air passage opening of the tank by a valve operated by a single lever so that it can alternatively cause vacuum or pressure in the tank, thereby allowing liquid to be drawn into the tank to measure it using the graduations and then to be forced out of the tank.
