Abstract

Apparatus for performing diagnostics through a regulator is disclosed. The pressure regulator is disposed in a fluid flow passage and has a throttling element (32) moveable in the flow passage. A
stem (30) is attached to the throttling element. The apparatus includes a first pressure sensor (34) for measuring pressure upstream of the throttling element, a second pressure sensor (35) for measuring pressure downstream of the throttling element, and a travel sensor (44) for detecting the position of the throttling element. A processor is provided which includes a stored algorithm for determining flow rate based on the measured pressure and travel values, and an alarm routine for generating logic alarms based on the measured operating parameters.
