Abstract
A remote diaphragm seal is provided. The remote diaphragm seal includes a flange coupled to a deflectable diaphragm configured to come into contact with a flow of process fluid along a first side of the diaphragm. The flange includes a fluidic passageway in fluidic communication with a second side of the deflectable diaphragm, the fluidic passageway including a substantially incompressible fluid. The flange also includes at least one additional passageway in fluidic communication with the first side of the deflectable diaphragm.

A remote diaphragm seal, comprising:
- a flange coupled to a deflectable diaphragm, the deflectable diaphragm configured to contact a process fluid along a first side of the deflectable diaphragm, the flange including:
- a fluidic passageway in fluidic communication with a second side of the deflectable diaphragm;
- and
- at least one additional passageway in fluidic communication with the first side of the deflectable diaphragm.

A remote diaphragm seal, comprising:
- a deflectable diaphragm comprising a first side configured to contact a process fluid and a second side in fluidic communication with a process transmitter;
- a flange coupled to the deflectable diaphragm, the flange including:
- a fluidic passageway coupled to the second side of the deflectable diaphragm and the process transmitter, the fluidic passageway containing a relatively incompressible fluid;
- and
- at least one additional passageway coupled to a flushing connection configured to receive a flow of cleaning fluid from the flushing connection and provide the flow of cleaning fluid to the first side of the diaphragm.
2 more elements
A flushing ring comprising:
- a body configured to mount adjacent a deflectable diaphragm;
- a first passageway disposed in the body, the first passageway being configured to be in fluidic communication with a process fluid in contact with the deflectable diaphragm;
- a first valve operably coupled to the first passageway, the first valve having a first valve stem configured to selectively engage a seat within the first passageway to selectively allow fluid flow therethough;
- a second passageway disposed in the body and being configured to be in fluidic contact with the process fluid;
- and
- a second valve operably coupled to the second passageway, the second valve having a second valve stem configured to selectively engage a seat within the second passageway to selectively allow fluid flow therethrough.
