In order to achieve remote monitoring of liquid ammonia storage tank, a major hazard, a plan based on Siemens S7-200PLC and configuration Wang software was proposed in this paper. The software and hardware of the monitoring system were designed, so that the real-time data of ammonia concentration in ammonia tank room, liquid level and pressure of ammonia tank were all displayed. As well, data reports real-time recording and inquiry, alarm information records and inquiry, curve real-time display, and SMS submitting of alarm were all achieved. The results show that this system can well realize remote monitoring of the liquid ammonia tank.
