1mm Accuracy Non Contact Radar Level Gauge OEM 100m Water Tank Level Measurement
The 1mm Accuracy Non-Contact Radar Level Gauge is an outstanding product. It offers extremely precise measurement with an accuracy of 1mm. As an OEM device, it is suitable for water tank level measurement up to 100m. Its non-contact design reduces wear and tear, providing reliable and long-term performance for various industrial applications.
1.Product Dimension
2. Working Principle
The radar antenna transmites narrow microwave pulse which will be reflected back when reaching the surface of the medium tested and then received again by the antenna system. The signals shall be transmitted to the electric circuit and then converted into level signals. As the transmission speed of microwave is so fast, the time used for the microwave transmission to the surface of the medium tested and then reflected back is almost 0.
3. Technical Features
⚫ Millimeter wave radar, the measurement accuracy can reach up to ±2mm, and the minimum measurement blind zone is 0.05m.
⚫ The smaller antenna size satisfies the measurement of more working conditions.
⚫ A variety of lens antennas, smaller launch angles, more concentrated energy, stronger echo signals, and higher reliability than other radar products under the same industrial and mining conditions.
⚫ It has stronger penetration and can be used normally in the case of adhesion and condensation.
⚫ The dynamic signal range is larger, and the measurement of low dielectric constant media is more stable.
⚫ Multiple measurement modes, radar response in fast measurement mode

The larger the antenna size and the smaller the beam angle α, the less interference echoes will be generated.
For more accurate measurements, avoid installing any internal devices (such as limit switches, temperature sensors, bases, vacuum rings, heating coils, baffles, etc.) within the range of the signal beam.
