Abstract A string vibration type densimeter is disclosed. The waveguide tube with protective sleeve tube has a lower end connected to waveguide sucker. The protective sleeve tube between controller and waveguide sucker is sleeved by at least one cylindrical magnetic density float with central through hole. Said float can move up and down along the protective sleeve tube. The lower ends of at least three balance tubes are uniformly and vertially fixed to top surface of the said density float and can move with the densit float. Its advantages are automatic real-time measuring and reading out, high accuracy, and high corrosion resistance.
