According to the present invention, a blanket level meter for measuring the height of sludge comprises: multiple detectors (6) installed in water, and transmitting and receiving ultrasonic waves in order to measure the height of the blanket level of sedimentation sludge (12) on the bottom of a first sedimentation tank (8) and the height of the shape of floating sludge (14) in a second sedimentation tank (10); and a converter (4) capable of controlling the ultrasonic waves, which are transmitted and received by the detectors (6), by managing the detectors (6) by each of channels (C1, C2, ..., and Cn), and capable of simultaneously measuring the height of the blanket level of the sedimentation sludge (12) and the height of the shape of the floating sludge (14) by measuring time differences between the transmitted and received ultrasonic waves and the speeds of the transmitted and received ultrasonic waves, wherein the one converter (4) is capable of simultaneously controlling the ultrasonic wave detector (6), which measures the blanket level of the sedimentation sludge (12) deposited on the first sedimentation tank (8), and the ultrasonic wave detector (6) measuring the height of the floating sludge (14) floating in the water in the second sedimentation tank (10) so that sewage treatment and waste water treatment for the sedimentation sludge (12) and the floating sludge (14) can be efficiently performed. |
