Included in the Prior Art Database: 2005-Feb-02
A battery powered, computerized instrument is disclosed for measuring tank solution parameters of a chemical process line in real time without shutting down the line. It is especially suitable for environments hostile to human presence and/or to confined areas where cabling to an off line energy source cannot be accommodated. Measuring instrument 1 comprises a boxlike structure 2. A conduit 3 descends from structure 2 and is connected by support webs 4 to a series of vertically spaced radially extending tubes 5 on which are mounted, for example, ultrasonic sensors 6. On conduit 3 may also be mounted temperature sensors 7, a PH sensor 8 and electrical conductivity sensor 9. Wiring (not shown) connected to the various sensors is disposed within the tubes 5 and conduit 3 for connection to electrical circuitry within structure 2.
