Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a guided wave radar liquid level meter detection device. Background Art

[0002] The guided wave radar level meter is a radar level meter based on the principle of time domain reflection. The electromagnetic pulse of the radar level meter propagates along the steel cable or probe at the speed of light. When encountering the surface of the medium to be measured, part of the pulse of the radar level meter is reflected to form an echo and returns to the pulse transmitter along the same path. The distance between the transmitter and the surface of the medium to be measured is proportional to the propagation time of the pulse between them, and the liquid level height is calculated.

[0003] In order to verify the accuracy of the guided wave radar level meter, it is necessary to perform a detection operation on the guided wave radar level meter. Usually, a reflector is used to collect the electromagnetic pulses emitted by the level meter, and the moving distance of the reflector is compared with the data obtained by the level meter for detection. In actual use, the electromagnetic pulses emitted by the guided wave radar level meter contact the liquid medium, and the detection by the reflector is not authentic enough, and it cannot be well adapted to the actual use environment of the guided wave radar level meter. Therefore, those skilled in the art have proposed a solution for a guided wave radar level meter detection device. Utility Model Content

Moreover, the area of ​​the floating plate 19 is smaller than the area of ​​the left part of the inner cavity of the pool body 11, so as to prevent the floating plate 19 from contacting the inner wall of the pool body 11 during the floating process, thereby causing the floating plate 19 to shake or get stuck with the inner wall of the pool body 11.

[0027] The liquid level meter suspension mechanism 2 includes an L-shaped support rod 21 fixed to the right side of the front surface of the pool body 11 , a three-jaw clamp 22 fixed to the rear section of the L-shaped support rod 21 , and a guided wave radar liquid level meter 23 clamped inside the three-jaw clamp 22 .

[0028] The front and rear side walls and the bottom surface of the partition 12 are fixedly connected to the inner cavity side walls of the pool body 11, and are used to divide the inner cavity space of the pool body 11 into two parts, wherein the inner cavity of the pool body 11 is filled with equal amounts of clean water. The back of the pool body 11 is provided with two symmetrically arranged circular holes for the water inlet pipe 13 to penetrate into the inner cavity of the pool body 11.

[0030] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

After an equal amount of liquid is injected into the glass measuring cup 14 at the same time, the liquid is released into the left and right parts of the inner cavity of the pool body 11 through the valve 15 and the water inlet pipe 13 in turn. When the liquid on both sides increases in equal amounts, the float plate 19 moves upward due to the buoyancy, driving the ring of the front section of the cross bar 17 to move on the outer ring of the cylindrical scale 16, so as to obtain the liquid level height data. Similarly, the liquid level data obtained by the guided wave radar level meter 23 is read by the computer, and the effect of the guided wave radar level meter 23 is detected by comparing the values ​​on the left and right sides.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
