PRESSURE RANGE CODE SELECTOR (IMPORTANT: READ BEFORE ORDERING)
Examine the pressure application and determine what is the Highest System Line Pressure.
Determine what is the Differential Pressure being measured.
Find the MAX. Line Pressure in the table on the right that is > to your Highest System Line Pressure.
Verify that your DP falls within the selectable ranges in that row.
Follow that row to the left and select that range code.
Example:
Highest System Line Pressure:
Differential Pressure Measured:
"Max Line Pressure" ≥ to System Line Pressure:
