Abstract

The invention discloses a guided wave radar level meter. The guided wave radar level meter comprises a guided wave rod, mounting devices are arranged at two sides of a gauge outfit, each mounting device comprises two first mounting rods, cavities are arranged in the first mounting rods; sliding chutes are arranged at two sides of each cavity, a second mounting rod is arranged in each cavity; sliding blocks are arranged at two sides of one end, in the cavity, of each second mounting rod, limiting posts are arranged on the bottom end of each second mounting rod and the bottom of the inner wall of each cavity; pressure springs are connected between the limiting posts; a mounting plate is connected between top ends of the second mounting rods; in the mounting, the second mounting rods are inward compressed by utilizing the elasticity of the pressure springs and the cooperation of the sliding blocks and the sliding chutes, thereby obtaining the length matched with a tank opening; and the effect of fixing the guided wave radar level meter can be achieved by utilizing the elasticity of the pressure springs; and the device has the advantages of being simple in structure and convenient to mount and can be adapted to different tank opening sizes.

Description

technical field [0001] The invention relates to the technical field of radar liquid level gauges, in particular to a guided wave radar level gauge. Background technique [0002] Guided wave radar level gauge is a liquid level measuring instrument commonly used in the chemical industry. Guided wave radar level gauge is a radar level gauge based on the principle of time domain reflection. Guided wave radar is a measuring instrument based on the principle of time travel. Radar waves run at the speed of light, and the running time can be replaced by electronic components. The high-frequency pulse is transmitted along the cable or rod probe. When the pulse meets the surface of the material, it is reflected back and received by the receiver in the instrument, and the distance signal is changed into a level signal. The electromagnetic pulse of the guided wave radar level gauge propagates along the guide rod or waveguide cable at the speed of light. When encountering the surface of...
