Specific gravity monitoring mechanism of construction method recorder

The utility model discloses a specific gravity monitoring mechanism of a construction method recorder. The device comprises a monitoring cylinder, a pressure sensor and a differential pressure sensor,a slurry inlet pipe is arranged on one side of the bottom of the monitoring cylinder; a slurry outlet pipe is arranged on one side of the top of the monitoring cylinder; clamping sealing pieces are arranged on the outer sides of the slurry inlet pipe and the slurry outlet pipe; the utility model discloses a specific gravity monitoring mechanism of a construction method recorder. A clamping sealing piece is arranged at the slurry inlet pipe; therefore, the slurry inlet pipe and the monitoring cylinder are convenient to disassemble and connect; the slurry inlet pipe is convenient to clean; therefore, the flow rate and the pressure difference in the slurry inlet pipe are ensured; the specific gravity monitoring efficiency of the monitoring cylinder is improved; the differential pressure sensor is extruded by the mea
