Guided Wave Radar Level Measurement Module
Radar Level Measurement
Guided wave radar electronic module for liquid and solid radar level transmitter
Guided wave radar measurement modules are used in level transmitters for liquids and solids. They work based on TDR (Time Domain Reflectometry) technology and can be combined with cable, rod, or coaxial probes to provide continuous and low-maintenance measurement. They perform reliably even in environments with condensation, foam, buildup, crystallization, or steam. Each guided wave radar electronic module is built to deliver stable and accurate readings in different industrial environments and to keep reliable performance even after long periods of use. They are also suitable for measuring the interface between two liquid layers or for applications with heavy vapor. With advanced signal processing, they stay stable even when the signal is weak or affected by interference. The nonlinear output function can convert measurement signals into practical data such as volume, weight, or flow, offering flexible use across various process applications.
