Hydro-Air - Model RDS91 (20m) -Radar Level Transmitter

Hydro-Air RDS series radar level meter has 6 different series (91, 92, 93, 94, 95 & 96) for various measuring ranges and different kinds of antennas. It is a compact series level transmitter for non-contact continuous level measurement of liquids and solids. In radar level measurement, microwaves are transmitted by the antenna system of the radar sensor to the measured product, reflected by the product surface, and received back by the antenna system. The time from emission to reception of the signals is proportional to the level in the vessel. RDS series has different types of antennas including cone type, anti-corrosion type, water droplet antenna, and conical plastic type for various types of applications.
