Adjustable radar liquid level meter

Abstract

The invention relates to the technical field of detection instruments, and discloses an adjustable radar liquid level meter. A ball sleeve movably sleeves the middle of a mounting disc, a mounting adjusting ring movably sleeves the top of a hydraulic ring cavity, and a transmission gear shaft meshed with a tooth key is movably mounted in a transmission cavity; the top of the gear shaft extends out of the bottom face of the mounting disc and is fixedly connected with a clamping strip; a resistor disc is fixedly mounted in a resistor cavity, an electric shock head is sleeved with an adjusting hole in an interactive mode, a clamping block is movably sleeved with a sliding groove, and a one-way valve is fixedly mounted at the communication position of the sliding groove and a hydraulic groove; a pressure relief hole communicating with the sliding groove and the hydraulic groove is formed in the position, located at the top of the one-way valve, in the mounting disc, a telescopic hole movably sleeves an electromagnet, and mounting is facilitated by arranging and mounting the adjusting ring on the mounting disc and cooperating with the clamping strip; and meanwhile, the radar liquid level meter can be accurately adjusted through the structural design of the ball sleeve, a resistance circuit and the like which are arranged inside.

Description

technical field [0001] The invention relates to the technical field of detection instruments, in particular to an adjustable radar liquid level gauge. Background technique [0002] Radar liquid level meter 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 converted into level signals through electronic components. The principle is that the probe emits high-frequency pulses that propagate in space at the speed of light. When the surface of the material is reflected back, it is received by the receiver in the instrument, and the distance signal is converted into a level signal, because the non-contact measurement of the radar level gauge has been used in many applications, but it is not very convenient in actual use: [0003] 1.

Problems solved by technology

[0002] Radar liquid level meter 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 converted into level signals through electronic components. The principle is that the probe emits high-frequency pulses that propagate in space at the speed of light. When the surface of the material is reflected back, it is received by the receiver in the instrument, and the distance signal is converted into a level signal, because the non-contact measurement of the radar level gauge has been used in many applications, but it is not very convenient in actual use:

[0003] 1. The radar level gauge for measurement is generally installed on the top of the liquid tank but not in the middle, and the installation method is to use the cooperation between the flanges and then fasten with bolts. This method has a simple structure , but in the actual installation, it is necessary to tighten the bolts one by one, the operation is more time-consuming, and the subsequent disassembly is also time-consuming, and it is possible to cause the flange due to the different tightness of the tightening through a single gradual tightening. The installation does not fit well, so that the liquid level gauge after installation is not correct, which will affect the subsequent measurement accuracy;

[0004] 2. The existing radar level gauges are installed directly on the top of the liquid tank to be tested, so that when the measurement part changes inside the same tank, the liquid level gauge cannot be directly adjusted for continued use, but needs to be disassembled Re-adjust the installation plane, and this radar level gauge is not necessarily universal when installed on different tanks, which reduces its applicability, that is, the existing liquid level gauge cannot be adjusted and needs to be disassembled Reinstallation is troublesome and inconvenient to use
