Problems solved by technology

[0005] The purpose of the present invention is to provide a corrosion-resistant radar liquid level gauge to solve the lack of protection for the probe part of the liquid level gauge proposed in the above background technology. Since the probe is placed inside the tank, the humidity of the detected liquid is high and the long-term The exposed corrodes the probe, and the probe liquid level gauge is also exposed to the outside, and the service life is low

Abstract

The invention discloses a corrosion-resistant radar liquid level meter which comprises a mounting base, a protective cover, a protective base and a liquid level meter body, a fixing base is fixedly mounted at the top end of the mounting base, a fixing plate is fixedly mounted at the top end of the fixing base, a wave guide rod is fixedly mounted in the middle of the bottom end of the mounting base, and a sliding rod is fixedly mounted on the side of the bottom end of the mounting base; the bottom end of the sliding rod is slidably sleeved with a protection base, and the bottom end of the rotating rod is fixedly connected with a rotating disc in the protection cover. The movable protection base is arranged at the bottom of the mounting base, when the movable protection base slides to the bottom end, the wave guide rod is protected, the corrosion resistance of the wave guide rod is improved, meanwhile, the protection cover is arranged at the top of the mounting base, the liquidometer body is protected, the rotary disc is rotated, and the hanging ring is pulled through the traction rope, so that the protection base is driven to ascend, the protective side plate is driven to clean thewave guide rod and the liquid level meter body in sequence, the device is simple in structure, the wave guide rod and the liquid level meter body can be protected respectively, and the service life iseffectively prolonged.

Description

technical field [0001] The invention relates to a liquid level gauge, in particular to a corrosion-resistant radar liquid level gauge, belonging to the technical field of measurement. Background technique [0002] The radar level gauge is a general-purpose radar level gauge. It is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits a high-frequency pulse that propagates in space at the speed of light. When the pulse encounters the surface of the material, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signal. Liquid level measuring instruments usually need to work in volatile gases, In harsh environments such as high temperature, high pressure, steam, vacuum and high dust, the requirements for the corrosion resistance and oxidation resistance of the...
