Claims

[Claims for Utility Model Registration] (1) A pulley is attached to one shaft of a magnetic joint, a torque sensor for measuring the transmitted torque is attached to the other shaft of this magnetic joint, and the pulley is wound around the pulley. A displacer is attached to one end of the string-like body, and a balance weight is attached to the other end of the string-like body, and the torque generated in the pulley when the displacer is immersed in liquid is detected by the torque sensor. A liquid level or liquid density measuring device characterized in that the liquid level or liquid density is measured based on the detected output. (2) The liquid level or liquid density measuring device according to claim 1, which is provided with an idler pulley for changing the hanging position of the string-like body wound around the pulley.
