The antenna types of radar level transmitters can be classified into threaded type, flange type and bracket type according to the process connection type.
Threaded type
Advantage: Easy for installation
Disadvantage: The process connection requires a corresponding female thread, and the transmission angle and direction of the radar signal cannot be adjusted.
Anti-corrosion integrated flange type
Advantage: Corrosion-resistant, excellent sealing performance, higher signal radiation efficiency, faster attenuation at the near-end, better performance for small-range and near-end measurement. Recommended for applications such as corrosive liquids, small tanks, agitator, steam and etc.
Disadvantage: Higher cost
Adjustable flange type
Advantage: The transmission angle and direction of the radar signal can be adjusted. It is recommended for complex structures inside the tank/silo or bulk solids. The air purge can be added for use in applications with heavy dust.
Disadvantage: It can only be used for ATM conditions and cannot be used for pressure storage tanks.
Adjustable bracket type
Advantage: The transmission angle and direction of the radar signal can be adjusted. It is recommended for open-type working conditions. For example, mining, raw material storage yards, open-type tanks and open channels.
Disadvantage: It can only be used for ATM conditions and cannot be used for pressure storage tanks.
