Problems solved by technology

It is also known that, for accurate measurements to be provided by the GWR level system, the measurement of the product level and / or the interface between two products with different dielectric constants at a distance of more than about 50 m below the tank top is a challenge

example

[0045] The disclosed embodiments are further illustrated by the following specific examples, which in no way should be construed as limiting the scope or content of the invention.

[0046] COMSOL simulation result data specific to time-domain reflectometry measurements is described below, showing an initial interrogation pulse with a peak value of 1.8 V and a half-maximum of 0.5 ns according to disclosed embodiments for different geometries of the feedthrough Full Width (FWHM), and an example of an echo (pulse) from the end of the feedthrough (flange location) and a metal target (ideal electrical conductor) located 1 m from the signal source (generating the aforementioned voltage peak) , the echo is a spurious echo. Between these two echoes, there may be other spurious echoes originating from multiple reflections from the end of the feedthrough and from the metal target. The simulation results compare the voltage echo obtained from the disclosed feedthrough with the voltage e...

Abstract

A coaxial feedthrough (feedthrough 100) for coupling a received process connection (2) to a storage tank (tank 40) comprising an inner electrical conductor (probe) (10), an outer electrical conductor (20); and a dielectric sleeve disposed between the probe and the outer electrical conductor. The dielectric sleeve is configured to provide an upper coaxial transmission line segment (upper CTL segment) (100a), the upper coaxial transmission line segment providing an impedance of substantially 50 ohms; and a lower coaxial transmission line segment (lower CTL segment) (110b), said lower coaxial transmission line section comprising one or more subsections (100b 1 and 100b 2 , 100b' or 100b''), the subsection has an impedance that is at least forty percent (40%) higher than the impedance of substantially 50 ohms.

Description

technical field [0001] The disclosed embodiments relate to a feedthrough for guided wave radar (GWR) level measurement of product in a storage tank. Background technique [0002] It is standard practice to use larger storage tanks (also known as containers) (hereafter referred to as "tanks") to store a variety of products, including liquids such as beverages and petroleum products, and solid products such as powders. Conventionally, such tanks are usually made of non-stainless steel plate, and in the case of petroleum products, the tanks are usually made of welded together from 1 / 4 inch (0.63 cm) to 1 / 2 inch (1.27 cm) Made of thick steel plate. Conventional storage tanks typically range in size from hundreds of feet (100 feet = 30.5 meters) in height and hundreds of feet in diameter. [0003] Where other sensing methods may struggle to provide reliable and / or accurate information, for example GWR-based contact electromagnetic detection and sensing can be used to determine ...
