Process Flow Calculations

The square-edged concentric orifice plate, along with a differential pressure transmitter, is a commonly used flow measuring device for liquid, steam, and gas services. Implementing or modifying a flow loop that utilizes an orifice plate and differential pressure transmitter can be complicated and time consuming. One must first gather a large amount of data and then perform some fairly complex calculations. This Web utility is my attempt to put all the necessary information into one convenient location and provide easy to use flow calculators. Flow measurement engineering is a very broad and complicated subject.  For a single source very exhaustive handbook, I recommend Flow Measurement Engineering Handbook by Richard W. Miller.
