Abstract:A liquid level measurement and multi-point inspection tour system for oil tanks based on magnetostriction effect were developed. The system was composed of a liquid level gauge, an inspection tour instrument and an application computer program. The design principle was introduced. Factors affecting the measuring accuracy were discussed. The EIA-485 field bus of the system's topology, the communication model and the protocol were also introduced. The system has the advantages of a simple and practical design, stable operation and comparative high accuracy.
Keywords:magnetostriction liquid level inspection tour
