👉 The index fluid, also known as the index liquid or index oil, is a critical component in the operation of an index fluid system, often used in industrial and laboratory settings. It serves as a reference medium to calibrate and standardize measurements of pressure, flow rate, and temperature. The fluid typically has a stable and well-defined physical state, ensuring consistent performance across various applications. By comparing the fluid's properties to known standards, operators can accurately monitor and control processes, making it indispensable for precision in industries ranging from chemical processing to scientific research.
