Abstract
A fluid flow system for continuously monitoring the flow of fluid including fluid flow conduit with an upstream side and a downstream side, sensors and fluid flow elements, with the method for analyzing the operation of a fluid flow system by determining whether the fluid flow subsystem of the main system is operating properly, inputting a sensor reading of the parameter in the fluid flow of the main system and outputting an error indication of the main system.
Claims19
A method for analyzing an operation of a fluid flow element of a fluid flow subsystem of a main system, comprising:
- inputting at least one sensor reading from at least one sensor of the fluid flow subsystem, the at least one sensor reading indicative of a value of at least one parameter of the fluid flow subsystem;
- analyzing the at least one sensor reading to determine a value of at least one of the at least one parameter;
- comparing the at least one determined value to at least one corresponding value;
- outputting an error indication of the fluid flow subsystem based on the comparison.
A method for analyzing an operation of a fluid flow element of a fluid flow subsystem, comprising:
- determining a deterioration rate of a reading measured by a sensor of the fluid flow system;
- determining a rate of use of a main system;
- and
- determining an amount of remaining use of the main system before the sensor reading will drop below a first value.
A method for analyzing the operation of a fluid flow system, comprising:
- polling at least one sensor value;
- polling at least one machine metric;
- comparing the polled at least one sensor value with the polled at least one machine metric;
- determining whether the polled at least one sensor value and the polled at least one machine metric correlate;
- and
- tracking down a source of the discrepancy between the polled at least one sensor value and the polled at least one machine metric.
A fluid flow system for continuously monitoring the flow of fluid, comprising:
- a sensor reading analyzing circuit, routine or application;
- an indication determining circuit, routine or application;
- and
- a main system shutdown determining circuit, routine or application.
