Abstract

An Arrangement for the measurement of a level of a medium in a container the arrangement allows for removal of the microwave level measurement device, without opening the container, which allows use of standard connectors. The arrangement comprises: a mounting section surrounding an opening of the container; a tubular adapter comprising a first standard connector located on a first end of the adapter and a second standard connector located on a second end of the adapter, which is mounted on the mounting section of the container by the first standard connector; an isolation window transparent for microwaves seating a passageway through the adapter having an outer rim, which is clamped between the mounting section and the first standard connector; and a microwave level measurement device, comprising a standard process connector to be mounted on the second connector of the adapter.

Claims

1. An arrangement for measurement of a level of a medium in a container, comprising:

a mounting section surrounding an opening of the container,

a tubular adapter having a first standard connector located on a first end of said tubular adapter and a second standard connector located on a second end of said tubular adapter, said tubular adapter being mounted on said mounting section of the container by said first standard connector;

an isolation window transparent for microwaves for sealing a passageway through said tubular adapter, and having an outer rim, which is clamped between said mounting section and said first standard connector; and

a microwave level measurement device, including a housing, which is mounted on a tube, said tube comprising a process connector located on an end of the tube for mounting said microwave level measurement device on said second standard connector of said tubular adapter, and an antenna, which is entirely located inside the tube, wherein;

said tubular adapter allows for removal of the entire microwave level measurement device without breaking the seal of the container provided by said isolation window;

said isolation window further has a cone including a tip which faces the container.

2. The arrangement according to claim 1, wherein:

a gasket is inserted between said mounting section of the container and said tubular adapter.

3. The arrangement according to claim 1, wherein:

said isolation window is made of a plastic material.

4. The arrangement according to claim 1, wherein:

said first standard connection and said second standard connection are formed as flanges.

5. A microwave transparent process seal for mounting on a mounting section surrounding an opening of a container, and used with a microwave level measurement, device, including a housing, which is mounted on a tube, said tube comprising a process connector located on an end of said tube for mounting said microwave level measurement device, and an antenna which is entirely located inside said tube, comprising:

a tubular adapter, said tubular adapter having a first standard connector located on a first end for mounting said tubular adapter on said mounting section of the container, and a second standard connector located on a second end of said tubular adapter onto which the entire microwave level measurement device is to be mounted via the process connector of said tube; and

an isolation window transparent for microwaves, for sealing a passageway through said tubular adapter, and having an outer rim, which is clamped between said mounting section and said first standard connector, when said tubular adapter is mounted on said mounting section, wherein;

said tubular adapter allows for removal of said entire microwave level measurement device without braking the seal of the container provided by said isolation window, and

said isolation window further has a cone including a tip which faces the container.
