Advantages

• Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
• Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.
• Serious dust environment on the high level meter work has little effect.
• A shorter wavelength, the reflection of solid surface inclination is better.
• Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
