I am building a refinery and the specifications are not clear.It is used with flanged or pancake style remote diaphragm seals. The main advantage is that you can you can perform this task without disconnecting the remote seal from the process flange. This can be accomplished by sandwiching the calibration ring between the remote seal and a blank process flange. Primarily seals are used in viscous, high temperature and corrosive application where the transmitter diaphragm is incapable of handling the process.http://classiccharters.com/pages/delta-320-ph-meter-manual.xml

Contact Community Manager All rights reserved. For this design, the seal and capillary are submersed in the process and installation is made through a connection at the top of the tank. This differs from traditional DP Level installations which are side mounted to tanks via threaded, flanged or hygienic connections, with only the diaphragm seal in contact with the process. The unique design of the Submersible Seal allows installation through small tank connections while at the same time providing excellent performance and sensitivity characteristics. Rosemount 1199 Submersible Seal July 2013 Proven, Reliable, and Innovative Remote Seal Technology for Top Down Measurement Unlike traditional DP Level systems that use flat diaphragm seals to measure process pressure, the Submersible Seal consists of a compressed bellows design. In addition, this seal design provides significantly better performance compared to a similar sized traditional DP Level diaphragm seal.http://docspaydocs.com/userfiles/descargar-manual-gratis-de-excel-2007.xml The Rosemount 1199 Submersible Seal can be combined with any Rosemount In-Line Gage Transmitter including all output protocols and hazardous location approvals.

Using non-nuclear qualified products in applications that require nuclear-qualified hardware or products may cause inaccurate readings.https://labroclub.ru/blog/boss-gt6-manual-portugues For information on Rosemount nuclear-qualified products, contact your local Emerson Sales Representative. During operation, the thin, flexible diaphragm and fill fluid separate the pressure sensor of the transmitter from the process medium. The capillary tubing or direct mount flange connects the diaphragm to the transmitter. When process pressure is applied, the diaphragm is displaced, transferring the measured pressure through the filled system, by way of the capillary tubing, to the transmitter. This transferred pressure displaces the sensing diaphragm in the pressure sensor of the transmitter. Transmitter diaphragmD. Fill fluidE. Transmitter pressure sensor 2.0 PrefaceThis guide is designed to assist with general handling and installation instructions for the Rosemount DP Level Transmitters and 1199 Diaphragm Seal Systems. The Rosemount DP Level Transmitters and 1199 Diaphragm Seal Systems Reference Manual contains supplemental information about the seal system assemblies that are not covered in the corresponding transmitter manuals. If any issues, contact your local Emerson sales representative immediately. The material of a remote seal is designed to withstand pressure and wear from process material, but outside of process connection conditions, remote seals are delicate and should be handled with care. The protective cover should remain on the seal until the moment before installation. Try to avoid touching the diaphragm with fingers or objects and refrain from setting the diaphragm side of the seal down on a hard surface. Even minor dents or scratches in the diaphragm material may impair the performance of the seal system assembly. Avoid sharply bending or crimping the capillary tubing. The minimum bending radius of the capillary tubing is 3-in. (8 cm). When using heat or steam tracing, exercise caution if PVC coating is added onto capillary. The PVC coating on the armor will break down at temperatures around 212 F (100 C).http://jms-stavebni.com/images/97-tahoe-repair-manual.pdf Best practice for heat and steam tracing is to regulate the temperature above the maximum ambient temperature for a consistent result. To avoid accuracy effects and thermal stress, the capillary should not be partially heated. 4.0 Mechanical installation 4.1 Mounting the seal system in vacuum applicationsMounting the pressure transmitter at or below the bottom vessel tap is an important factor to ensure a stable measurement with vacuum applications. The static pressure limit for a differential pressure transmitter is 0.5 psia (25 mmHgA), which ensures the transmitter sensor module fill fluid remains within the liquid phase of the vapor pressure curve. If the vessel static limit is below 0.5 psia, mounting the transmitter below the bottom tap provides a capillary fill fluid head pressure on the module. A general rule in vacuum applications is to mount the transmitter approximately 3 ft. (1 m) below the bottom tap of the vessel. Capillaries are to be securely fastened in order to avoid false readings. NOTICENever attempt to disconnect the seals or capillaries from the transmitter or loosen bolts. However, it is always best practice to insulate systems to keep them functioning with optimum performance. The Thermal Range Expander should never be insulated above the line marked on the seal itself, see the figure below for reference. Figure 2. Thermal Range Expander System Insulation Considerations 4.3 Flanged type seals Gaskets When installing remote seal systems which employ a gasket or a gasket and flushing connection ring, make sure the gasket is aligned properly on the gasket sealing surface. Failure to properly install the gasket may cause process leaks, which can result in death or serious injury. In addition, make sure the gasket does not press down upon the diaphragm face. Anything pressing on the diaphragm will be read by the transmitter as pressure. A misaligned gasket may cause a false reading or damage the diaphragm. The diaphragm gasket is supplied when a lower housing or flushing connection is provided. The default gaskets are listed below, based on seal type. The process gasket must be supplied by the end user. Tantalum diaphragms are not supplied with default gasket, so a gasket option must be selected when applicable. If a flushing ring is used, its MWP should also be verified. Bolt torquing When connecting the process and mating flange, the bolts should be torqued to the applicable flange requirements. Required torque is a function of the gasket material and surface treatment of the bolts and nuts which are customer supplied. 4.4 Pancake type seal options Capillary support tube A common option for the pancake type seal (PFW) is the capillary support tube. Due to the side capillary-to-seal connection, the support tube provides a handle for aligning the pancake seal during installation. The support tube should not be used for supporting any weight above that of the remote seal. Process flange Emerson offers the option of supplying the process flange, otherwise the process flange is furnished by the customer. For certain pancake seal assemblies, the Emerson supplied process flange has a machined hole through the center of the flange.
