Non-Metallic Flow-Through Electrodeless Conductivity Sensor With Leak And Temperature Detection
US Patent:
7279903, Oct 9, 2007
Filed:
Jan 5, 2007
Appl. No.:
11/650154
Inventors:
John Kevin Quackenbush - Middleboro MA, US
Michael M. Bower - Wareham MA, US
Stephen B. Talutis - Milton MA, US
Donald S. McKinlay - Wareham MA, US

Assignee:
Invensys Systems, Inc. - Foxboro MA
International Classification:
G01N 27/06, G01N 27/74
US Classification:
324445, 324439, 324204
Abstract:
A non metallic flow through electrodeless conductivity sensor is provided with a conduit having primary and secondary process fluid flow paths to form a fluid loop. At least one drive and one sense toroid surround the conduit on the fluid loop. Voltage supplied to the drive toroid induces a current in the sense toroid via the fluid loop to eliminate any need for metallic electrodes in contact with the process fluid. At least one additional drive and/or sense toroid is disposed on the fluid loop to enhance induction. Optionally one or more sense coils are disposed about the conduit outside of the fluid loop to cancel out stray electrical noise. An optional conductor disposed along the conduit detects any fluid leakage through changes in resistance thereof. A temperature detector is supported within an electrically non-conductive holder extending into the fluid flow path, so that the detector is free from physical contact with the fluid. An optional enclosure is provided with ports to enable a user to purge any gas permeating the conduit walls.

Assignee:
Invensys Systems, Inc. - Foxboro MA
International Classification:
G01N 27/02, G01R 27/08, G01R 35/00
US Classification:
324446, 324601, 324691
Abstract:
A calibration plug provides resistance simulation for calibrating toroidal conductivity sensors. This calibration plug includes a resistive element of predetermined electrical resistance coupled in series between electrical leads which may be engaged with a circuit element to form an electrical circuit. The toroidal sensor includes one or more toroidal coils defining a central bore extending therethrough, a cell factor, and a full scale conductivity value. The predetermined resistance of the resistive element is determined in accordance with the following equation:.

Abstract:
A non metallic flow through electrodeless conductivity sensor is provided with a conduit having primary and secondary process fluid flowpaths to form a fluid loop. At least one drive and one sense toroid surround the conduit on the fluid loop. Voltage supplied to the drive toroid induces a current in the sense toroid via the fluid loop to eliminate any need for metallic electrodes in contact with the process fluid. At least one additional drive and/or sense toroid is disposed on the fluid loop to enhance induction. Optionally one or more sense coils are disposed about the conduit outside of the fluid loop to cancel out stray electrical noise. An optional conductor disposed along the conduit detects any fluid leakage through changes in resistance thereof.

Assignee:
Invensys Systems Inc. - Foxboro MA
International Classification:
G01R 31/28
US Classification:
3241581
Abstract:
This invention relates to electrical connectors used with non-invasive toroidal conductivity sensors and calibration thereof. A removable breaking calibration connector is provided for temporary insertion in the electrical circuit to selectively break connection to a sense toroid for zero out calibration in situ while retaining connection to the drive toroid and other peripherals, even when process fluid is flowing in the pipes.
