6401555, Jun 11, 2002

Filed:

Jun 14, 1999

Appl. No.:

09/333070

Inventors:

James R. Bowers - Lakewood OH 44107

International Classification:

G01D 2100

US Classification:

738665, 138110

Abstract:

A tube packing extension assembly is provided, wherein a conventional cap fitting with plug fitting is replaced with a tube packing extension enclosure that incorporates an extended, linearly elongated outer tube sheath for circumscribing in a concentric manner any tube end that extends outward from the outer conduit sidewall. This outer tube sheath is formed as attached to a tube fitting connection nut, and provides an extension, of selectable size, that extends outward from the conduit sidewall, yet fully encloses and protects the end of the sensing tube. A tube packing extension cap can thereby be removably affixed to the outer end of the tube packing extension enclosure outward by a sufficient length should any brushing or purging of the tubes be required.

International Classification:

US Classification:

7386166

Abstract:

A high temperature gas flow sensing element module, using Pitot tube technology, for use within a fluid conduit consisting of a housing having an inlet, an outlet, and forming a hollow interior cross-sectional area. Individually, the gas flow sensing element modules fit easily through typical furnace access doors. Thus, in typical furnace retrofit applications, a plurality of equally sized gas flow sensing element modules are arranged adjacent one another in a manner such that the inside dimensions of the entire arrangement coincide with the internal dimensions of the plenum or duct opening into which it is inserted. Pressure averaging piping is used to provide average total and static pressure across the entire gas flow sensing element to differential pressure flow indicators and/or transmitting devices.

Appl. No.:

Inventors:

James R. Bowers - Lakewood OH 44107

International Classification:

F16K 2400

US Classification:

137204, 137557

Abstract:

An automated condensate drain system for gas flow elements is provided that includes a differential pressure transmitter, a sequence controller, and two condensate chambers for receiving and collecting accumulated moisture from air flow elements and transmitters. The condensate chambers are placed in low profile positions within the instrument piping system, requiring downward sloping of the instrument tubing to accentuate condensation drainage. The sequence controller initiates a drainage cycle (set as desired by operator), permitting the transmitter to enter an auto-zero cycle, thereby energizing an internal isolation valve in the transmitter while maintaining the transmitter output. The sequence controller energizes solenoid valves of the two condensate chambers, wherein the chambers open to permit drainage of accumulated moisture assisted by static pressure system. After the drainage cycle is completed, the sequence controller de-energizes solenoid valves and returns the drain valves to a closed position and the transmitter returns to normal operation.

Inventors:

James R. Bowers - Lakewood OH, US

International Classification:

G01F001/46

US Classification:

7386165

Abstract:

An improved manual purge system for periodically cleaning pressure sensing flow element tubing is provided that is a complete self-contained system for allowing manual determination and initiation of flow element purging. Additionally, the system can be easily upgraded to an automatic purge system without removal from the process system.

James R. Bowers - Lakewood OH, US

International Classification:

G01F 1/46
G01D 21/00

US Classification:

7386165, 738665

Abstract:

A tube mounting assembly for total traverse or static traverse sensing tubes is provided for use with Pitot tube devices where the tubes are allowed to expand and contract independent of the flow element shell. A female threaded pipe cap is tack welded or otherwise affixed to the inside internal surface of the flow element shell. A inch NPTX tube fitting of the bore-thru fitting type is affixed to the pipe cap, and a traverse tube, sealed by high temperature packing or thread sealant between the tube and a tube nut, are then affixed to the opposite end of the bore-thru tube fitting.

Appl. No.:

Inventors:

James Bowers - Rocky River OH

International Classification:

G01F 146

US Classification:

7386166

Abstract:

Disclosed is a high temperature insertion type flow element and mounting extension assembly for a gas flow measuring device. Designed to overcome the drawbacks associated with compensating for differential thermal expansion between the element and the duct wall, the element consists of an otherwise conventional insertion type flow element, that incorporates the use of a mounting extension assembly and an expansion fitting. The mounting extension positions the element head in an offset manner from the gas duct, placing the element head in a position away from any insulating materials encasing the duct, allowing for convenient access to the instrumentation and cleaning ports. The expansion fitting stabilizes the element tubes within the duct while absorbing any differential thermal expansion.

International Classification:

G01F 146

US Classification:

7386166

Abstract:

A pitot tube having a series of pressure sensing ports on the upstream side of the tube and a second series of pressure sensing openings on the downstream side of the tube. A longitudinal internal wall in the tube forms a pair of chambers, one of which communicates with the upstream ports and the second which communicates with the downstream ports. A plate attached to the end of the tube has diverging passages communicating with the two chambers, the plate forming a flange for connecting a manifold, a transmitter for indicating the flow pressures sensed by the ports, a gauge or the like.

Appl. No.:

Inventors:

James R. Bowers - Rocky River OH

International Classification:

G01F 146

US Classification:

7386166

Abstract:

A high temperature gas flow sensing element is disclosed having a housing with similar internal dimensions as the fluid conduit, whether round or rectangular. An interior flow conditioner is affixed at the inlet of the flow element. A total pressure sensing pitot tube array is affixed traversing the interior cross sectional area of flow element for sensing the total pressure of fluid flowing into the flow element, and a static pressure sensing pitot tube array is also affixed traversing the interior cross sectional area of the flow element for sensing the average static pressure within the flow element. The pitot tubes and pressure sensing tubes are affixed at four places, two shell penetrations and two places at the manifolds, regardless of manifold design or the element shape. To prevent material stress and fatigue and leakage that can result from the different expansion rates of differing materials under high gradient temperature cycling, a high temperature packing, such as a ribbon packing or packing ring made of pliable material resistant to high temperatures, is used in place of the ferrule portion of a compression nut and fitting arrangement. Exterior first and second instrument taps are provide for connection of each array respectively to a differential pressure instrument for indicating flow rate and/or transmitting a flow rate signal.
