A self-circulation pressure meter anti-freezing device belongs to the technical field of pressure meter anti-freezing device. One end of an emptying valve is connected with a communicating valve, a pressure meter control valve and a pressure meter, the other end of the communicating valve is connected with an outlet inclined tube, the other end of the pressure meter control valve is connected with an inlet inclined tube, and the inlet inclined tube and the outlet inclined tube are respectively connected with a liquid outlet pipeline. The self-circulation pressure meter anti-freezing device has the advantages that aiming at the condition that the existing thickened oil production pressure meter device is poor in anti-freezing effect in winter and the normal recording of pressure data in oil field production is severely affected, the self-circulation pressure meter anti-freezing device solves the problem, greatly reduces the labor intensity of workers, reduces the usage amount of thawing steam and pressure mete
