A weighing apparatus for weighing liquids which includes a balance beam pivotally supported from a pivot pin and having first and second members of equal weight supported on opposite sides of the pivot point, one of the members being adapted to be positioned in the liquid to be measured for displacing a predetermined volume of liquid. A fluid piston and cylinder assembly fixedly supported and in contact with the beam whereby the buoyant force exerted on the one member is transmitted to the fluid assembly and a pressure gauge connected to the assembly for measuring the pressure therein which is an indication of the weight of the liquid in which the one member is inserted. The one member including first and second horizontal sections of different cross-sectional areas with the upper cross-sectional area being smaller whereby the volume of fluid being displaced when the member is inserted in the fluid is accurately measured. The beam including a vertical extending shoulder adjacent the pivot point which is in contact with the fluid assembly thereby multiplying the buoyant force applied by the liquid to the fluid assembly.
