Intrusive acoustic sensor mounting arrangement
First Claim
1. In combination, an acoustic fluid sensor, an acoustic window and a flange assembly for mounting said sensor and window on a fluid tank, said flange assembly having a body portion configured to extend through an opening in the tank wall in a fluid-tight manner into the tank interior, said flange assembly having a body flange that is attachable to the tank wall;
- said body portion having a fluid passageway therein and a port that permits fluid in the tank to flow into said passageway;
said flange assembly further comprising means for retaining said acoustic window in said passageway;
said sensor comprising a body that is insertable in said fluid passageway in a fluid-tight manner;
said sensor further comprising an active surface acoustically coupled to said window by fluid in the tank when said sensor is fully inserted in said passageway.

12. An intrusive mounting arrangement for mounting an acoustic sensor to the wall of a fluid tank, said mounting arrangement comprising a flange assembly attachable to the tank wall, said sensor having an acoustic element and further being mateable and unmateable with said flange assembly;
- said flange assembly comprising an acoustic window and means for biasing said window to a first position when said sensor is unmated to prevent loss of fluid and for permitting said sensor to displace said window from said first position when mated to said flange assembly to permit container fluid to couple said acoustic element and said window acoustically.

17. A method for intrusively mounting an acoustic sensor in a fluid tank comprising the steps of:
-
a. mounting a flange assembly having a fluid passageway at a through hole in the fluid tank in a fluid-tight manner; b. sealing the flange assembly passageway to prevent fluid loss by positioning a acoustic window means to block said passageway when the sensor is uncoupled from the flange assembly; and c. displacing said blocking means when the sensor is coupled to the flange assembly to permit fluid to wet an acoustic element of the sensor. - View Dependent Claims (18, 19)

- 20. An intrusive mounting arrangement for mounting a sensor on a fluid tank, the mounting arrangement comprising a flange assembly attachable to the tank wall and having a fluid passageway therein, the sensor being adapted to mate and unmate with the flange assembly in the fluid passageway, the sensor being wetted by fluid when mated to the flange assembly and the flange assembly comprising means for preventing fluid loss when the sensor is unmated therefrom, wherein the preventing means comprises an acoustic window disposed in the fluid passageway, and means for permitting the sensor to be acoustically coupled to the window by tank fluid when the sensor is mated with the flange assembly.
- 23. An intrusive mounting arrangement for mounting an acoustic transducer in a fluid container, said transducer being of the type that uses an acoustically active element and an acoustic window, said mounting arrangement comprising means for intrusively mating and unmating said transducer with the fluid container, and means for providing a wet interface between said active element and said window using fluid in the container.
