  • Publication number: 20230010460
    Abstract: Various automated cleaning systems for internal cavities of pressure instruments are disclosed. The systems comprise a computer controlled fluid flow system that enables the use of various cleaning fluids for cleaning internal cavities of pressure instruments to high cleanliness levels. Various pressure instruments, including complex shapes such as Bourdon tube gauges, are accommodated. The system can include a computerized cleaning cycle selection and a multi-fluid combination of cleaners for efficient and low cost cleaning solution. A servo controlled agitation system can allow for filling, evacuation, and drying of aqueous solutions as well as high performance solvents for Oxygen Clean service.
