Abstract
A method can include receiving, at a control module, first pump characteristic data from a data source associated with a pump, sensing second pump characteristic data from a flow system using one or more sensors, comparing the first pump characteristic data to the second pump characteristic data sensed in the flow system, and determining a health of the pump based on the comparison of the first pump characteristic data to the second pump characteristic data.
Claims15
A non-transitory computer readable medium comprising computer executable instructions to cause a computerized device to perform a method, the method comprising:
- receiving, at a control module, first pump characteristic data from a data source associated with a pump;
- sensing actual first pump characteristic data from a flow system using one or more sensors;
- comparing the first pump characteristic data to second pump characteristic data;
- determining a health of the pump based on the comparison of the first pump characteristic data to the second pump characteristic data;
- and
- storing the first pump characteristic data until shut down or reset of the flow system to allow an update of the first pump characteristic data at each start-up;
- wherein receiving the first pump characteristic data includes receiving the first pump characteristic data at start-up and/or initialization of the control module, wherein receiving the first pump characteristic data includes receiving the first pump characteristic data only at start-up and/or initialization of the control module.
A system, comprising:
- a control module for a flow system, the control module configured to perform a control module method, the control module method comprising:
- receiving first pump characteristic data from a data source associated with a pump, wherein receiving the first pump characteristic data includes receiving the first pump characteristic data at start-up and/or initialization of the control module;
- sensing second pump characteristic data from a flow system using one or more sensors;
- comparing the first pump characteristic data to the second pump characteristic data sensed in the flow system;
- determining a health of the pump based on the comparison of the first pump characteristic data to the second pump characteristic data;
- and
- storing the first pump characteristic data until shut down or reset of the flow system to allow an update of the first pump characteristic data at each start-up.
A pump, comprising:
- a pump housing containing one or more pump components;
- and
- a data source mounted on or in the pump housing, the data source comprising first pump characteristic data configured to be read from the data source to provide a control module with the first pump characteristic data at start-up and/or initialization of the control module, wherein the control module is configured to store the first pump characteristic data until shut down or reset of the flow system to allow an update of the first pump characteristic data at each start-up.
