Claim 5:
6. A fluid supply system, comprising:
a fluid pump configured to receive a fluid from a first conduit disposed upstream of the fluid pump and to discharge fluid into a second conduit downstream of the fluid pump;
a pressure sensor configured to produce signals representative of a sensed fluid pressure;
a pressure relief valve (PRV) having an inlet and an outlet and a fluid passage therethrough, wherein the PRV is controllable to be in a closed configuration, or a fully open configuration, or a plurality of partially open configurations, wherein the PRV is in signal communication with the pressure sensor; and
a fluid monitoring device having an upstream orifice (UO) in fluid communication with the second conduit, a downstream orifice (DO) in fluid communication with a third conduit, and a sensing chamber (SC) in fluid communication with both the UO and the DO, wherein the SC includes a sensing orifice;
wherein the pressure sensor is disposed to sense fluid pressure at the sensing orifice of the SC.
