The accelerometer comprises a liquid ring and a digital circuit. The liquid ring comprises an operating fluid, a ring, a capillary tube, a solvent compensator, an electrode and a converter. The ring and the solvent compensator are connected together. When a temperature changes, the volume of the work liquid also changes. Through the capillary tube, the operating fluid in the ring and the operating fluid in the solvent compensator are interconnected so as to fill the volume change of the liquid in the ring, wherein the volume change is generated because the temperature changes. One converter is inlaid in the ring. The converter is made of a material which is formed through sintering an insulating material and possesses capillary pores. Two sides of the converter are provided with noble electrodes respectively. And the converter is connected to the digital circuit through the electrodes.
