Filed:

Aug 2, 2012

Appl. No.:

13/565305

Inventors:

Jay Scheldorf - Bellville TX, US
Gokhan Aydar - Austin TX, US
Blake Becker - Brenham TX, US
Derek Poehlmann - Brenham TX, US
Bruce Muske - Burton TX, US

International Classification:

G01F 23/14

US Classification:

73299

Abstract:

An apparatus is provided for measuring level of a process fluid in a container opening. The apparatus includes a remote seal configured to be inserted into the container through an opening and configured to receive a pressure related to the level of process fluid in the container. A capillary tube filled with a fill fluid extends from the remote seal to the opening and is configured to convey the pressure therebetween. A pressure sensor coupled to the capillary tube senses the pressure from the capillary tube and responsively determines the level of the process fluid in the container. The remote seal includes a bellows portion arranged to isolate the process fluid from the fill fluid in the capillary tube and convey the pressure therebetween.

International Classification:

G01F 1/44
G01L 7/08

US Classification:

73 498, 7386163

Abstract:

A remote seal assembly for subsea applications is provided. The assembly includes an upper housing having a fluid coupling for coupling the remote seal to a process fluid pressure measurement device. A lower housing is coupled to the upper housing and has an interface that is configured to mount to a pressure vessel. The lower housing also has a process fluid inlet. An isolation diaphragm is disposed between the upper and lower housings. At least one of the upper housing, lower housing and isolation diaphragm are constructed from a material suitable for immersion in saltwater. In some embodiments, the lower housing has a shoulder disposed about the process fluid inlet and a plurality of self-energizing seals configured to couple the assembly to a venturi flow meter body. A subsea process fluid flow measurement system is also provided that includes a pressure transmitter and at least one subsea remote seal assembly.

International Classification:

F16K 7/12
F16K 31/126

Abstract:

There is provided a filter for a diaphragm valve. The filter attaches to a diaphragm of the valve and filters fluid entering a control chamber in the valve. The filter includes internal structure that increases the path from where fluid enters the filter through a mesh of holes to a single exit flow path leading to the control chamber. This increased path reduces the potential for debris in the flow to clog the exit flow path from the filter.
