Summary:PURPOSE:To provide a liquid detector, wherein a resonance-type vibration unit is rigidly mounted on a housing, a measuring-liquid container and a pipe by a mounting member, active resonance is accelerated even in the rigid mounting, the disturbance factors caused by overhead supporting are excluded as much as possible, and the highly reliable measurement can be performed. CONSTITUTION:A vibration unit has a vibrator 1 in the circular direction, a liquid detecting piece 3, which is resonated with the vibrator l in the circumferential direction, and a vibration transfer member 2, which links the vibrator 1 in the circumferential direction and the liquid detecting piece 3 and undergoes torsional vibration at the time of the resonance. In this vibration unit, a mounting member 6, which mounts the vibration unit at the specified position of the part including the node O of the resonace located at the halfway of the vibration transfer member 2, is provided. Both ends of the vibration unit are made to be the free vibrating ends. Thus, the resonance-type liquid detector is constituted.
