  • Wellsite mixer sensing assembly and method of using same
    Patent number: 10213755
    Abstract: A mixer sensing assembly of a mixer for mixing a wellsite fluid in a tank at a wellsite is provided. The mixer includes a shaft driven by a driver and a paddle operatively connectable to the shaft and rotatable therewith. The sensor assembly includes a mount operatively connectable to the shaft, a fluid interface, and a mixing sensor. The fluid interface is responsive to flow of the wellsite fluid passing thereby, and is connectable to the mount. The mixing sensor is connectable to the mount, the fluid interface, and/or the shaft to measure a strain applied to the thereto whereby fluid parameters of the wellsite fluid may be determined. The wellsite fluid may be mixed moving the components in the tank with the mixer, and measuring a strain on the mixer by detecting movement of the sensor assembly.
