Radar level gauge winter antifreeze instructions

How to solve the antifreeze of radar level gauge? 1. Electric heating/electrical tracing heat preservation: electric heating/electrical tracing heat preservation is to use the resistance wire wound on the main pipe of the magnetic flap level gauge to heat the pipe so that the liquid in the pipe is above the freezing point to ensure that the tank body The liquid will not freeze because the temperature is too low. 2. Vacuum jacket insulation: The vacuum jacket insulation level gauge is to install an insulation jacket outside the main body of the main pipeline, and introduce a heat medium such as steam to maintain the normal flow of the liquid in the main body. In this way, It is more suitable for liquid level measurement and control of easily solidified liquids. For low-boiling liquids, the stability of the liquid level can be ensured by adding refrigerants such as cold water, so that the instrument can measure the liquid level. Precautions for the use of radar level gauge 1. The measurement range of the radar level gauge should be calculated from the time it touches the beam, but if the bottom of the radar level gauge is concave, it should be calculated from its lower point. 2. When using radar level meter, pay attention to the dielectric permittivity of the measured medium. If the medium has a low dielectric constant, when it is at a low liquid level, it is better to set the zero point at the low height of C, so as to obtain Better measurement accuracy. 3. When using the radar level gauge for measurement, the influence of corrosion and adhesion should be considered, and the final value of the measurement range should be at least 100mm away from the tip of the antenna. 4. When using the radar liquid level meter, a safety distance should be set to be attached to the blind area, which can play a role in overfill protection.
