Multi-functional level probe mounting device

Claim 1

In a fluid measurement system for feeding fluid in controlled amounts from a tank to a treatment line, a fluid volume measurement structure comprising: a container connected to said tank such that fluid may be transferred from said tank to said container; said container comprising an upper end and a lower end; a first mounting means connecting said tank to said upper end of said container and having an interior portion defining a first flow passage; a second mounting means connecting said lower end of said container to said treatment line and having an interior portion defining a second flow passage; a first sensor aperture in said first mounting means for mounting a first fluid sensor in fluid communication with said first flow passage; a second sensor aperture in said second mounting means for mounting a second fluid sensor in fluid communication with said second flow passage; a third sensor aperture in said first mounting means for mounting a first liquid capacitance sensor therein, said third sensor aperture comprising a first planar wall surface contiguous to said first flow passage and adapted to block fluids in said first flow passage from entering said third sensor aperture, said first planar wall surface adapted for contacting a first capacitance sensor for sensing capacitance changes of liquid in said first flow passage; and a fourth sensor aperture in said second mounting means for mounting a second liquid capacitance sensor therein, said fourth sensor aperture comprising a second planar surface contiguous to said second flow passage and adapted to block fluids in said second flow passage from entering said fourth sensor aperture, said second planar wall surface adapted for contacting a second capacitance sensor for sensing capacitance changes of liquid in said second flow passage.
