About GUIDED WAVE RADAR LEVEL TRANSMITTER

INTRODUCTION HCDAR-5x series adopts the contact measurement method and can be used for the continuous level measurement of liquid, solid particles, small size oil storage tanks, offers continuously measurement of the level of conductive and non-conductive liquids, particles and slurries. The measurement won’t be affected by medium type, pressure, temperature, inert gas, steam, dust and foam, etc. The accuracy
could reach to 3mm, max measuring range can be 30m, high temperature resistance could be 250? and high pressure resistance can be 2MPa.

WORKING PRINCIPLE HCDAR-5X series is a level measuring instrument based on time travel principle. The electromagnetic wave emitied by the radar antenna propagates along the cable or rod probe. When the pulse reaches the surface of the material, it is reflected back and received by the antenna. The distance signal is converted to level signal. The distance D to the material surface and the pulse travl time T is propor-tional: D=C*T/2. Where C is the speed of light, and the level of solid/liquid is obtained.

FEATURE HCDAR-5X guided wave radar level transmitier emit constant electromagnetic wave, and there is no need for on-site calibration and migration to change the range. The installation method is simple and diverse, and the measurement will not be affected by temperature, pressure, density changes. HCDAR-5X series have no moving parts, so there is no mechanical parts damage problem and no need for maintenance. Almost all liquid and solid particle media can be measured.
