Pressure monitor optimizaiton of fluid path utilization
First Claim
1. A method of monitoring pressure in a fluid system comprised of at least one fluid path section having a first end and a second end and at least one controllable pressure source connected to said first end of at least one fluid path section and responsive to a pressure command signal to create a source pressure in said at least one fluid path section, said method comprising:
- providing a device comprising;
a pressure monitor for placement in communication with a fluid in said fluid system, said pressure monitor generating a signal representative of a measured pressure;
a control means for receiving said signal representative of said measured pressure and for sending signals to said fluid system;
providing said control means with a library having entries comprising sets of command signals and sets of normal pressure values;
comparing said measured pressures to said normal pressure values;
reporting differences that exceed a preset threshold;
placing said pressure monitor in communication with a fluid in said at least one fluid path section;
issuing a pressure command signal from said control means to one of said controllable pressure sources to generate said source pressure in said at least one fluid path section; and
comparing said measured pressure to a reference said normal pressure values and reporting differences that exceed a preset threshold to identify errors in said fluid system.

Abstract
A device comprising a pressure monitor and a control means that receives a signal representing measured pressure at the pressure monitor and controls the controllable elements of a fluid system is utilized to monitor a fluid system for error conditions, to optimize operations and to diagnose the fluid system. By following a testing protocol that selectively enables parts of the system, the control means narrows the list of possible failing components. Comparing the measured pressure against normal pressures allows the device to identify error conditions. Determining the volume of fluid being transported and controlling the duration of the flow optimizes operation of the fluid system.
