The Difference In Application Of Radar Level Transmitter Frequency Range Dirty and polluted environment With long-term use, dirt and pollutants accumulated on the antenna will affect the strength and direction of the radar signal. For high frequency signals, any dirt that covers the antenna will absorb more energy, and the direction of the beam may change. This results in a loss of signal strength. So, low-frequency and medium-frequency technologies are more suitable. Storage tanks with condensate and/or steam Condensation and steam can cause reflections on product surfaces to be masked by the “noise” of water droplets. This is more of a problem for high frequency signals. So mid and low frequency techniques are a better choice. Antennas with flat, horizontal surfaces should always be avoided for condensation. High steam and agitation Be sure to choose the 80G millimeter-wave radar level meter. The 80G radar level meter has a high transmission frequency and has good penetration and is not affected by steam. The 2° transmission angle can effectively avoid the interference of the stirring blade. The unique echo Tracking algorithm avoids reading multiple echoes when the material level is high. Applications with turbulence, waves and ripples Waves and ripples are often found on the surface of process liquids in large tanks. And this turbulence is especially detrimental to high-frequency measurements. Low and mid frequency level instruments emit longer wavelengths, making them perform better. Foam application Like dust and condensation, a layer of foam on top of the liquid can absorb the radar signal, making accurate measurements more difficult.
