FIELD: physics. ^ SUBSTANCE: vibrating liquid level indicator contains armature connected to sensing element in the form of pin-type rod, pulse generator, amplifier, core-type coil exciter connected to output of pulse generator, core-type coil armature movement pickup connected to amplifier input. Thus sensitive element of vibrating level indicator is supplied with equally spaced vanes planes of which are oriented perpendicular to vibration direction. Vanes area decreases by core end. Besides, level indicator additionally includes detector with its input connected to output of amplifier, and display device with its input connected to detector output. ^ EFFECT: measuring of corrosive liquid or high-fluid bulk material level at high temperature and pressure. ^ 5 dwg |
