No. It is a recommended practice. However, OSHA’s Process Safety Management (29 CFR 1910.119) requires that equipment be built to “recognized and generally accepted good engineering practices” (RAGAGEP). API RP 551 is frequently cited as RAGAGEP in court and during incident investigations. In practice, it functions as mandatory for liability protection.

If you are building a complete engineering library, you will need all four. But for field instrumentation, is the starting point.

Proper mounting on absorbers, regenerators, and storage tanks to prevent operational hazards like overfilling.

Best practices for Coriolis meters, focusing on mounting stability to minimize external vibrational interference. 2. Level Measurement But for field instrumentation, is the starting point

API RP 551 serves as a comprehensive guide that bridges the gap between theoretical instrument engineering and practical, on-site application. It focuses on ensuring that devices—such as flow meters, pressure transmitters, and temperature sensors—deliver consistent, accurate, and reliable data. The primary objectives of this document are:

API RP 551, or "Process Measurement Instrumentation," is a foundational document for engineers, technicians, and designers working in the oil and gas industry. This Recommended Practice (RP) provides comprehensive guidance on the selection, installation, and configuration of instruments to ensure safety and reliability. 🏗️ What is API RP 551?

Operational guidance includes:
