Novel fuel gas odorizing device

The utility model provides a novel fuel gas odorizing device, aiming at solving the problems that most of liquid level meters of the conventional odorizing device adopt glass tube liquid level meters, and the glass tube liquid level meters are easy to break to cause material leakage; a metering pump (with upper and lower one-way valves) cannot lock the pressure, so that the material backflow phenomenon exists; and when the materials leak, the risk that the materials flow into soil or a ditch exists. A novel fuel gas odorizing device comprises a device body, and a liquid collecting pool is arranged at the bottom in the device body; an outlet of the metering pump is connected with a pressure preparation one-way valve; the liquid storage tank is provided with a magnetic turning plate liquid level meter; the first end of the first four-way valve is connected with the inlet of the metering pump, the second end is connected with the bottom of the liquid storage tank, the third end is connected with an inert gas val
