The HBRD70X series guided wave radar level gauge is a continuous level measurement product based on the principle of TDR (Time Domain Reflectance). The instrument has the advantages of high stability, high measurement accuracy, and wide application scenarios. Compared with instruments of other principles, the HBRD70X series products have the characteristics of being less affected by the change of the dielectric constant and density of the measured material, and are resistant to dust and fog.

The hardware system uses advanced microprocessors and embedded system processing software, and the signal algorithm processing integrates advanced Echocapture signal processing technology, making the product applicable to various complex industrial plant conditions.

The "empty tank preprocessing" technology enables the instrument to correctly identify effective echoes and obtain correct measurement results even in the presence of multiple false echo interference. It is not affected by various complicated working conditions, such as strong surface fluctuations, foam, water vapor and dust interference. Empty warehouse debugging is allowed, and the probe assembly can be shortened as required.
