Precautions for Radar Level Gauge Installation

What should be paid attention to in the installation of radar level gauge? Radar level gauge installation precautions Radar level gauge has the advantages of low maintenance, high performance, high precision, high reliability, long service life, etc. It can meet the requirements of volatile gases, high temperature, high pressure, steam, vacuum and high pressure in the process. Requirements for harsh environments such as dust. It can be used for continuous measurement in harsh environments such as high temperature, high pressure, vacuum, steam, high dust and volatile gases. Avoidance of installation problems of radar level gauge: 1. When installing the radar level gauge, the liquid inlet, feed curtain and vortex should be avoided, because the medium will generate a larger amplitude than the effective echo reflected by the measured liquid level during injection. many false echoes. At the same time, the irregular liquid level caused by the vortex will scatter the microwave signal, which will cause the attenuation of the effective signal; 2. For the container with a stirrer, the installation position of the radar level gauge should not be near the stirrer, because the stirring will generate Irregular vortex, it will cause the attenuation of the radar signal. At the same time, the blades of the stirrer will also cause false echoes to the microwave signal, especially when the relative permittivity of the measured object is small and the liquid level is low, the impact of the stirrer is more serious; 3. When the radar liquid level When the meter is used to measure the liquid level of corrosive and easy-to-crystallize objects, in order to prevent the influence of the medium on the sensor, the manufacturer generally adopts a structure with a PTFE measuring window and a separation flange. The temperature of these parts should not be too high, the temperature of PTFE is 200 ℃. In order to avoid the influence of high temperature on the radar antenna, and to prevent the crystals existing on the diaphragm from affecting the normal operation of the instrument, a safety distance of at least 100-800mm is required between the flange end face and the high liquid level.
