Abstract：Based on the analysis of saftey valve checking present situation, this paper describes the design of saftey valve check meter. This meter can perform the real-time measurement of pressure and displacement in a saftey check process, discriminates and display the open pressure and open height automatically. In addition, there is RS485 communication interface in this meter.
