US Patent 11467056 Sensing leak in a multi-seal sealing assembly with sensors

A multi-seal sealing assembly with sensors includes a housing, a first sensor and a second sensor. The housing can receive multiple seals and can mount to a surface of a tool. The multiple seals are configured to seal against fluid flow between the surface of the tool and the housing. Multiple sensors corresponding to the multiple seals are mounted to the housing adjacent respective seals and between the housing and the surface of the tool. The sensors sense a flow parameter at different levels responsive to an absence or a presence of fluid flow past the seals.
