摘要：PURPOSE:To obtain a title apparatus with the waveguide of ultrasonic waves and the receiver installed at an interval in a liquid to measure an equalized density and a level of a liquid with ununiform density distribution. CONSTITUTION:This apparatus comprises a waveguide 9 installed in a liquid tank 3 storing a liquid under test to radiate ultrasonic waves to the liquid under test, an ultrasonic transducer 8 which receives ultrasonic waves reflected from the boundary between the terminal of this waveguide 9 and the liquid under test, an ultrasonic receiver 11 which receives ultrasonic waves radiated into the liquid under test, and an arithmetic means which processes output signals from each receiver.
