Abstract
A diagnostic method for verifying the proper functioning of flow devices of a fluid system including at least one of at least one fluid heater, a bypass conductor connected in parallel to the at least one fluid heater, a bypass valve configured to control flow through the bypass conductor, at least one flow valve for controlling a fluid flow through the fluid system, at least one pump, at least one pressure sensor for obtaining a pressure of the fluid flow and at least one flow sensor for obtaining a flowrate of the fluid flow. The method includes selectively turning on and off the bypass valve and the at least one pump and obtaining pressure measurements at various times during the execution of the diagnostic method to identify the health of the at least one pressure sensor and the at least one pump.
