ABSTRACT:
A vibratory liquid detector which includes a detecting element secured to a free end of a vibration transmission shaft. The detector is suspended in a liquid and receives vibration from the vibration transmission shaft. A spring member supports the vibration transmission shaft and has a fixed end, secured to an intermediate portion of the vibration transmission shaft, and a free end located at a position spaced apart from the periphery of the vibration transmission shaft. The free end is also axially spaced from the fixed end, and includes a support part supporting the whole detecting unit. The spring member provides satisfactory elasticity with respect to torsional vibrations of the vibration transmission shaft between the fixed and the free ends, thus permitting adequate vibrational energy transmission from the vibrator to the detecting element via the vibration transmission shaft.
