1. The measurement range of a radar level gauge starts from the point where the beam reaches the bottom of the tank; however, in special cases where the tank bottom is concave or conical, measurement becomes impossible when the liquid level is below this point. 2. Theoretically, it is possible for a radar level gauge to measure the position up to the tip of the antenna, but considering the effects of corrosion and adhesion, the upper limit of the measurement range should be at least 100 mm away from the tip of the antenna. 3. When the dielectric constant of the medium is low and the liquid level is low, the bottom of the tank can be seen; to ensure measurement accuracy, it is recommended to adjust the zero point position upward accordingly. 4. The minimum measurement range is related to the antenna. 5. For overflow protection, a safety distance can be defined and added to the blind area. 6. With varying concentrations, foam in radar level gauges can either absorb microwaves or reflect them; however, measurements can still be taken under certain conditions.
