A liquid level measuring device for measuring the level of liquid in a storage or dispensing tank has an elongated tubular hollow body that carries a threaded coupler adapted for engaging a threaded nipple on top of the tank. A buoyant float is attached to a lower portion of the elongated body. The body slides in relation to the coupler while the coupler remains stationary in relation to the tank. As the liquid is dispensed from the tank, the buoyant float that was positioned on the surface of the liquid in the tank, lowers in relation to the tank, moving the elongated body into the tank. Measuring indicia placed on the exterior surface of the elongated body allows visual observation of the changing level of liquid in the tank.
