  • Acoustic determination of piston position in a modular dynamics tester displacement pump and methods to provide estimates of fluid flow rate
    Patent number: 9341169
    Abstract: A method for determining a piston position in a downhole tool, having steps of providing a transducer in the downhole tool, wherein the tool has a piston used to create a vacuum for the downhole tool, providing a transducer tone burst to provide acoustic energy toward the piston, reflecting the transducer tone burst by a surface of the piston, receiving the transducer tone burst at a receiver, calculating time of flight for the transducer tone burst and determining the piston position in the downhole tool based upon the calculated time of flight of the transducer tone burst.
