Guided wave radar level transmitter uses advanced microprocessor technology and unique EchoDiscovery echo processing technology, along with multiple process connection options and types of detection components. This makes the ZDW921 series suitable for various complex working conditions and applications, such as high temperature, high pressure, and media with low dielectric constants. The guided wave radar level transmitter operates in pulse mode with very low transmission power, allowing it to be installed in both metal and non-metal containers, with no harm to the human body or the environment.
