APPARATUS AND METHODS FOR DETERMINING PARAMETERS DOWNHOLE USING GRAVITY-AFFECTED SENSOR |
摘要 |
In one aspect, an apparatus for use in a wellbore is provided that in one embodiment includes a sensor having a plurality of spaced conductive contact elements, a sensing member that moves by gravity and contacts at least two contact elements in the plurality of contact elements to create an electrical short between such at least two contact elements and a circuit coupled to the contact elements configured to generate electrical signals in response to the electrical short between the contact elements. |
