Abstract
The present disclosure provides a method for predicting a fluid type, comprising sensing, by a first sensor, mass flow data of a fluid in an engine, wherein the first sensor operates based on a first fluid property; sensing, by a second sensor, mass flow data of the fluid, wherein the second sensor operates based on a second fluid property; and detecting, by a logic circuit of a controller, a percent difference in the mass flow data provided by the first and second sensors, the percent difference indicating that the fluid is comprised of at least a first fluid type.
Claims27
A fluid type prediction system, comprising:
- a first sensor that provides a first mass flow measurement of a fluid in an engine, wherein the first sensor is sensitive to at least a first property of the fluid;
- a second sensor that provides a second mass flow measurement of the fluid, wherein the second sensor is sensitive to at least a second property of the fluid;
- and
- a controller configured to detect a percentage difference between the first and second mass flow measurements indicating a presence of at least a first fluid type in the fluid, and to adjust a performance characteristic of the engine in response to detecting the percentage difference between the first and second mass flow measurements.
A fluid type prediction system, comprising:
- a controller comprising at least one processor and memory;
- and
- a first interface coupled to the controller, the first interface configured to receive parameter signals corresponding to a mass flow measurement of a fluid in an engine, the parameter signals being provided by at least a first sensor and a second sensor;
- wherein the memory comprises instructions that when executed by the at least one processor causes the controller to detect a percentage difference between the mass flow measurement provided by the first sensor and the mass flow measurement provided by the second sensor, the percentage difference indicating the presence of at least a first fluid type in the fluid, and to adjust a performance characteristic of the engine in response to detecting the percentage difference between the mass flow measurements provided by the first and second sensors.
