Pressure monitor optimization of fluid path utilization
First Claim
1. A device for monitoring pressure in a fluid system 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; and
a control means for receiving said signal representative of said measured pressure and comparing said measured pressure to a reference,wherein the control means is configured to determine a viscosity of a fluid flowing in the fluid system by multiplying the measured pressure by a 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 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.
