Problems solved by technology

[0008] The need to use different frequency bands means that different modules for flanges and sealing elements have to be provided, which leads to higher costs for keeping these different modules
This means that the finished product becomes more expensive for the consumer who has to choose one available module and another if a band change is required

Embodiment Construction

[0022] Referring to Figures 1, 2 and 3, a container 1 contains, for example, a liquid 2 article having a liquid level 3 measured by a non-contact radar measuring device 4 partially shown in Figures 1-3. Figures 2 and 3 show in more detail part of the measuring device 4, wherein Figure 2 shows the device 4 when using a relatively low frequency band, and Figure 3 shows the device 4 using a relatively high frequency band. A typical frequency band for the device 4 according to FIG. 2 has a center frequency of f=6 GHz and a general frequency band for the device 4 according to FIG. 3 has a center frequency of f=26 GHz.

[0023] The device 4 comprises a flange 5 mounted on the container 1 , wherein the container has an opening 6 into the container 1 allowing access to the interior of the container 1 . The opening 6 of the container 1 is made as an introduction on which there is an upper mounting portion 1a on which the flange 5 is mounted. The opening 6 of the container 1 is at leas...

Abstract

The present invention relates to a radar level measuring device for non-contact measurement of a level of a product in a container. The device comprises a flange which is mounted on the container in such a way that a lead-through of the flange at least partly covers an opening in the container. The device further comprises a waveguide part, insertable into the flange. When inserted, the insertable waveguide part is arranged to come to a stop at a distance (D) from the surface of the flange intended to face the container, along which distance (D), a waveguide is formed, forming a continuous waveguide together with the insertable waveguide part when inserted.

Description

technical field [0001] Radar level measuring device for non-contact measurement of product level in a container having an opening, said device comprising a flange with a lead-in for mounting on the upper mounting part of the container in such a way that The lead-in portion at least partially covers the opening and the contact surface of the flange abuts against the upper mounting portion of the container, the device further comprising a waveguide insertable into the flange. [0002] A parts list is included at the end of this application text. Background technique [0003] Fill level measuring devices using radar technology to measure the level of liquid substances in containers are used under those special conditions which make other liquid level measuring devices more or less inadequate. These conditions can be the temperature in the container, the pressure in the container, and the properties of the liquid. For example, the liquid may be a certain petroleum product or o...
