U-shaped density measuring instrument

The invention relates to a U-shaped density measuring instrument which comprises a U-shaped pipeline and a sensor assembly, and the bottom of the U-shaped pipeline penetrates through the sensor assembly and is in contact with a tension sensor in the U-shaped pipeline. The device further comprises rotating bearing frames which are symmetrically arranged and fixedly installed on the cross beam, and the rotating bearing frames are further connected with the left steel pipe and the right steel pipe of the U-shaped pipeline through connecting plates correspondingly. A connector part is installed at a port of the U-shaped pipeline and connected with the bottom of the cross beam through an L-shaped plate. A slurry conveying pipeline is directly connected into the U-shaped pipeline through the connector component, and under the gravity effect of slurry, the U-shaped pipeline descends around a rotatable fulcrum on the connector component through a rotating bearing support to drive a tension sensor in the sensor assemb
