Classification: CPC F  G | IPC F  G

Claim 0:
1. 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 a control orifice in fluid communication with the second conduit disposed upstream of the control orifice and a third conduit disposed downstream of the control orifice, wherein the second conduit has a first inner diameter, the third conduit has a second inner diameter, and the control orifice has an orifice inner diameter, and the orifice inner diameter is less than both the first inner diameter and the second inner diameter;
wherein the pressure sensor is disposed to sense fluid pressure in the third conduit at a position downstream of the control orifice in close proximity to the control orifice.
