Abstract
An improved housing assembly is used for a microwave level sensing instrument for sensing level of a process fluid in a vessel. The process vessel includes a vessel flange defining an opening into a storage space in the vessel. The housing assembly includes a flange assembly including a housing flange having a distal gasket face sealingly mateable with the vessel flange in use. The housing flange is connected to a window housing for housing a window spaced from the gasket face and providing a process seal. An electronics housing is mounted to the window housing. The electronics housing supports a microwave antenna proximate the window for focusing energy through the window to the process fluid.

In a microwave level sensing instrument for sensing level of a process fluid in a process vessel, the process vessel including a vessel flange defining an opening into a storage space in the vessel, an improved housing assembly comprising:
- a flange assembly including a housing flange having a distal gasket face sealingly mateable with the vessel flange, in use, and connected to a window housing for housing a window spaced from the gasket face and providing a process seal;
- and
- an electronics housing mounted to said window housing, the electronics housing supporting a microwave antenna proximate the window for focusing energy through the window to the process fluid.
In a microwave level sensing instrument for sensing level of a process fluid in a process vessel, the process vessel including a vessel flange defining an opening into a storage space in the vessel, an improved housing assembly comprising:
- a flange assembly including a window housing having an inner end and an opposite outer end, a housing flange mateable with the vessel flange, in use, and connected to the window housing outer end, a window received in the window housing intermediate the opposite ends providing a process seal, and retaining means mountable to the window housing from the inner end for retaining the window in said window housing;
- and
- an electronics housing mounted to said window housing at the inner end, the electronics housing supporting a microwave antenna proximate the window for focusing energy through the window to the process fluid.
A microwave level sensing instrument for sensing level of a process fluid in a process vessel, the process vessel including a vessel flange defining an opening into a storage space in the vessel comprising:
- an electronics housing supporting a microwave antenna;
- a flange assembly including a housing flange having a distal gasket face sealingly mateable with the vessel flange, in use, the housing flange being connected to a window housing;
- a window housed in the window housing and spaced from the gasket face and providing a process seal;
- and
- means for mounting the electronics housing to the window housing so that the antenna extends into the window housing proximate the window to focus microwave energy through the window to the process fluid.
