PROBLEM TO BE SOLVED: To provide a densitometer that is capable of relatively stable measurement without being affected by the influence of each kind of turbulence factor such as concentration distribution or the like in piping. SOLUTION: The densitometer for measuring the solid concentration in liquid 16 to be measured comprises a transmission section/reception section distance adjustment mechanism 9 for adjusting the distance between a transmission section 1 and a reception section 2 as shown by arrows A and B, an antenna stand rotational mechanism 6 for adjusting the angle of the antenna stand 5 as shown in an arrow C, an arm stretching mechanism 4 for stretching the arm 3 as shown by an arrow D, and an arm rotational mechanism 10 for rotating the arm around the axis as shown by an arrow E, thus varying the position, size, direction, and the like of a measurement area 17, and conducting measurement under optimum conditions without being affected by the influence of each kind of turbulence factor.
