Abstract

See full text

A fluid supply system and method is provided that includes a fluid pump, a pressure sensor, a pressure relief valve (PRV), and a fluid monitoring device. The fluid pump receives fluid from a first conduit and discharges fluid into a second conduit. The pressure sensor produces sensed fluid pressure signals. The PRV is in signal communication with the pressure sensor. The fluid monitoring device includes a control orifice in fluid communication with second and third conduits. 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 the first and second inner diameters. The pressure sensor senses fluid pressure in the third conduit at a position in close proximity to the control orifice. The fluid monitoring device may be in a lead or a lag domain configuration.
