| Abstract: | The principles of Time Domain Reflectometry(TDR) were introduced in the paper, aming at the application to liquid level sensing system. The influence of high temperature and high pressure on wave detection, and the theory of liquid level sensor system with pressure and temperature compensation were discussed in detail. In addition, a case of high-pressure heater in power plant was conducted for validation of this technology. |
