Pressure monitor optimization of fluid path utilization
First Claim
1. A method of determining viscosity of a fluid in a calibrated fluid system having a viscosity calibration factor, said fluid system comprising a controllable pressure source responsive to a pressure command signal to create a source pressure on said fluid, at least one fluid path section having an open end and a second end, and said controllable pressure source connected to said second end of said at least one fluid path section, said method comprising:
- providing a device comprising;
a pressure monitor in fluid communication with a fluid in said calibrated 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;
placing said pressure monitor in communication with said fluid in said at least one fluid path section at a known position on said fluid path section;
issuing a pressure command signal from said control means to said controllable pressure source to create said source pressure, said source pressure causing said fluid to flow; and
calculating a viscosity of said fluid using said measured pressure and said viscosity calibration factor.

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 falling 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.
