Abstract

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.

Tank Parameter Measurement System

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. Instrument 1 is placed in a basket 10 and sent through the process line with other baskets (not shown) of parts. When basket 10 is inserted into tank 11 containing chemical solution 12, parameter measurements are started by activation of float switch 13. Each parameter is read an operator selectable number of times, averaged, compared to a required value, then stored in memory for future readout. The time interval between parameter readings is also operator selectable. Tank 11 is one of a plurality of tanks placed along the process line beneath an overhead conveyor (not shown) from which basket 10 and other...
