1. Q. What is the measurement principle of the radar level meter?
A. It is a non-contact radar level/distance meter using the Frequency Modulated Continuous Wave (FMCW) method, operating at 76–81GHz.
2. Q. What are the advantages compared to ultrasonic level transmitters?
A. Unlike ultrasonic sensors, it is virtually unaffected by temperature, pressure, gas, vapor, or dust. Therefore, precise measurement is possible even in harsh internal tank environments.
3. Q. Can it measure regardless of the type of fluid?
A. Most liquids and solids (powders) can be measured. However, if the dielectric constant of the target material is too low, the radar reflection may be weak, so verification is required during the selection process.
4. Q. Can it be installed in high-temperature and high-pressure tanks?
A. Yes, it is possible. Radar level meters are available in models designed to operate stably in high-temperature and high-pressure environments by using non-contact sensors or specialized antennas.
5. Q. What is the maximum measurable distance?
Depending on the model, it can measure a wide range, from small tanks up to a distance of 120m.
Q. Can it measure even if there are obstacles (agitators, pipes) inside the tank?
A. While obstacles can cause interference, latest models feature a 'Mapping' function. This allows the device to identify and eliminate signals from fixed obstacles, filtering them out to accurately measure only the actual liquid level.
7. Q. Is it suitable for tanks containing highly corrosive chemicals?
A. Yes, by using models with antennas made of chemically resistant materials such as PTFE (Teflon) or PP, you can reliably measure highly corrosive fluids, including acids and alkalis, without any issues.
8. Q. Can it be used in storage bins with high dust levels (powder, grain)?
A. Yes, it is possible. In high-dust environments, we use non-contact radar or Guided Wave (contact) radar to minimize signal attenuation and ensure accurate measurement.
Q. What should be considered during installation?
A. The unit should not be installed too close to the tank wall (maintain a minimum clearance of 30–50cm) and must avoid being positioned directly above the inlet. The installation location should be determined by considering the radar beam angle.
Q. What types of output signals are supported?
A. We support the industry-standard 4-20mA analog output and HART communication as basic features. Depending on the model, various communication methods such as RS-485 (Modbus) can also be selected.
