A common process instrumentation application measures differential pressure in a steam line, with the final output being a flowrate measurement. The process instrument engineers or technicians who manage this application are concerned with accuracy and, typically, are focused on the transmitter, which is a critical piece of equipment and very important in providing an accurate output. However, the transmitter is only as accurate as the inputs provided to it. The process instrumentation loop (PIL) is just as important. The role of this loop is to present a set of process conditions to the transmitter. These conditions must be precisely the same as those in the process. If they are not, the
