    2151P Area Velocity Flow System Section 3 Programming 3.3.4 Flow Conversion The 2151P is capable of determining flow rates using either area velocity conversion or level-to-flow rate conversion. Table 3-1 lists the available flow conversion methods. The 2151P is capable of calculating and storing any two con- version methods simultaneously.
