Flush and Extended Diaphragm Use in Transmitters

Dear Raees,

Happy Ramzan

Like to see you our here, r u in Karachi or Lahore Office.

Please Note,

Flush flange seals include a mounting flange that assists in aligning the diaphragm with the process connection. A flush flange seal also allows the use of a flushing ring between the diaphragm and the process flange.

Flush flange seals with lowers are used when an adapter is required between the seal and diaphragm so that larger diaphragms can be used on smaller process connections.

Extended flange seals provide a choice of extension lengths that mount on a pipe flange and extend in toward the tank wall. The diaphragm can, therefore, sit flush with the inner face of the vessel.

Pancake seals consist of a flat cylindrical body with a centered flush-mounted diaphragm. The seal is mounted to the process flange with the use of a backup (blind) flange. The capillary connection is on the side of the pancake seal, enabling its use if the space on the outside of the vessel is limited or restricted. Because the flange is not a permanent part of this seal, the flanges do not need to have identical pressure ratings. Also, the blind flange may be fabricated from a different material of construction since it is not exposed to the process fluid.

If you require further information, please inform, i will send you some literature in this regard.
