A fluid flow monitoring, evaluation, and control system providing accurate
dispensing of fluids in low volume, high pressure systems. The system
includes one or more fluid flow sensors mounted on positive displacement
dispensing valves and a processor that receives cycle signals from the
fluid flow sensors to determine fluid flow information. If the fluid flow
is not within specified limits, a signal is sent to a pump control device
to adjust the pump to return the fluid flow to desired level. A
dispensing valve can include a display to show cycle time or other fluid
flow measurement. The system can include dispensing valves having single
inputs and single outputs for measuring fluid dispensed at a point of
use, which measurement can be compared to measurements taken at a divider
block earlier in the hydraulic path to verify that fluid sent into the
path was actually dispensed.
