Now, radar level gauges are used in many industries. Radar level gauge has many advantages. It is not only easy to install, but also has high measurement accuracy. If you want the radar level gauge to measure very accurately, then you need to master some selection skills. Next, I will tell you how to choose a radar level gauge
First of all, when we choose the type of radar level gauge, we must pay attention to the measurement range of the radar level gauge. If the measurement range of the radar level gauge we choose does not meet the actual requirements, it will not only fail to accurately measure the data, but it will also damage the radar level gauge. We need to calculate the measurement range that the light wave of the radar level gauge touches from the bottom of the tank. If the shape of the tank bottom is special, it cannot be measured. In addition, in order to measure whether the medium is corroded, we also need to clearly understand Second, if the medium we measure is moving, then in order to ensure the accuracy of the radar level gauge measurement, it is best to fix the still-wave tube at the bottom of the tank, and then Fix it in the middle. When measuring the liquid level of the welding radar, it is necessary to ensure that the inner wall of the stilling wave tube is smooth, so that the concave and convex points do not interfere with the guided wave.
Finally, when measuring a medium with a low dielectric constant, if its level is lower than the measured value of the liquid level, then we need to adjust the zero point to a position higher than the bottom of the tank. In actual use, it should be considered whether there is stirring in the container of the radar level gauge. If so, please pay attention to the selection
