The invention belongs to the technical field of liquid level detection devices, and particularly relates to a closed container liquid level position detection device which comprises a sound source, aninterdigital transducer, a double-layer structure flexible body and a hollow plastic pipe, the sound source and the interdigital transducer are distributed in a bilateral symmetry mode, and the double-layer structure flexible body is arranged below the sound source and the interdigital transducer. The lower end of the double-layer structure flexible body is fixedly connected with a hollow plasticpipe. The liquid level changes the propagation plane, the height of the liquid level is measured by changing the detected current after the piezoelectric effect, the device has the advantages of goodreal-time performance, high voltage resistance, electromagnetic interference resistance, wireless transmission and the like, the measurement system is accurate, and the system is more stable due to the double-layer structure.

Thermal insulation metal material
InactiveCN105538795ALow thermal conductivityHigh pressure resistantMetal layered productsThermal insulationMagnesium
The invention discloses a thermal insulation metal material. The thermal insulation metal material comprises a metal plate and thermal insulation layers respectively arranged at the upper plane and the lower plane of the metal plate. The metal plate is provided with filling holes. The inner diameters of two ends of each one of the filling hole are smaller than the inner diameter of the middle of the filling hole. The filling holes are filled with a filler. The thermal insulation layers are compressed to the two surfaces of the metal plate through a hot press. The metal plate is an alloy material layer prepared from iron, titanium, magnesium and copper. The thermal insulation metal material has the advantages of high pressure resistance, moisture resistance, thermal insulation, corrosion resistance and low heat conduction coefficient.
