PURPOSE:To fix frame bodies to a pipe to be measured tightly by arranging a clamping member which locks a chain fixing the frame bodies to the pipe to be measured across a spacer member opposite the spacer, and providing a fixing force adjusting means between them. CONSTITUTION:Echo sounder transducers 7A and 7B are provided between two opposite frame plates 40 and 41, and the block type spacer member 42 is fixed to both end parts. The frame bodies are fixed to the pipe 1 to be measured by the chain 50 across the spacer member 42. Both ends of the chain 50 are locked to the clamping plate 51 arranged facing the spacer member. Then, the frame body fixing force adjusting means consists of a screw part and a rotary knob part 5 for applying specific tension to the chain 50 and a pressing part 54. |
