Embodiment Construction

[0028] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] like figure 1 As shown, a device for measuring liquid level by guided wave of antenna type radar level gauge in this embodiment is used for measuring tank liquid level; it includes a radar level gauge 1 and a waveguide 2, and the radar level gauge 1 is installed In the tank, the radar level gauge 1 is connected with an antenna 11, the waveguide 2 is installed in the tank and sleeved outside the antenna 11, and the waveguide 2 is provided with A communication hole 22 for balancing the liquid level inside and outside the waveguide 2 .

[0030] Wherein, the waveguide is made of shielding material, for example, stainless steel 904L metal material can be used, and the wall thickness is 6mm. As a carrier, the...

Abstract

The invention relates to a device for measuring the liquid level by guided waves of an antenna radar liquid level gauge, which is used for measuring the liquid level of a tank body; it includes a radar liquid level gauge and a waveguide tube, the radar liquid level gauge is installed in the tank body, The radar liquid level gauge is connected with an antenna, the waveguide is installed in the tank and sleeved outside the antenna, and the waveguide is provided with a communication hole to balance the liquid level inside and outside the waveguide. The device of the present invention has the advantages of simple structure, convenient operation, accurate measurement, stability, reliability, and maintenance-free, and can be used in situations such as vacuum that require high environmental pressure; under normal pressure, the echo signal increases by 10 ‑15db, after vacuuming to 1kpa, the echo signal increased from 0db to 22db, in good condition.

Description

technical field [0001] The invention relates to the field of acid bath clean liquid level measurement in the viscose industry, in particular to a device for measuring liquid level with an antenna-type radar liquid level gauge guided wave which is different from the existing method for measuring the liquid level of acid bath crystallization in the chemical fiber industry. Background technique [0002] At present, there are many liquid level measurement methods at home and abroad, but for places where crystallization is easy in the tank and the vacuum pressure is high, there are limitations in the selection of instruments, and the selection is difficult. If the existing radar level gauge continues to be used, the liquid level cannot be measured normally, and the crystallization and vacuum cause the radar microwave signal to be lost. To replace and modify the existing radar level gauge, the cost invested by the company is as high as hundreds of thousands, and the effect after u...
