ABSTRACT:
An apparatus and method are disclosed for sensing a characteristic of a borehole. An exemplary apparatus includes a conductive pipe; an inlet, connected to the conductive pipe, for applying pulse to the conductive pipe; a resonant network device connected with the conductive pipe; and a transducer which is in operative communication with the resonant network device to measure a borehole characteristic, the transducer being configured to sense a modulated vibration frequency induced in the resonant network device when a pulse is applied to the inlet.
