Abstract
Apparatus and method for monitoring flow meter operation. In one embodiment, a flow metering system includes a flow meter and a condition monitor. The flow meter is configured to measure the volume of fluid flowing through the flow meter. The condition monitor is coupled to the flow meter is and configured to monitor a parameter of operation of the flow meter, and to record values of the parameter over a predetermined time interval. The condition monitor is further configured to determine reference values for the parameter based on the recorded values, and to apply the reference values to values of the parameter acquired after the predetermined time interval to validate operation of the flow metering system.
Claims21
A flow metering system, comprising:
- a flow meter configured to measure volume of fluid flowing through the flow meter;
- and
- a condition monitor coupled to the flow meter and configured to:
- monitor a parameter of operation of the flow meter;
- record values of the parameter over a predetermined time interval;
- determine reference values for the parameter based on the recorded values;
- and
- apply the reference values to values of the parameter acquired after the predetermined time interval to validate operation of the flow metering system.
A method for monitoring operation of a flow metering system, comprising:
- acquiring and recording, by a monitoring system, values of a parameter of operation of the flow metering system during a predetermined reference initialization interval of operation of the flow metering system;
- determining reference values for the parameter based on the recorded values of the parameter;
- validating the operation of the flow metering system by applying the reference values to values of the parameter acquired after the reference initialization interval.
A condition monitoring system for monitoring operation of a flow metering system, comprising:
- a reference initialization engine configured to:
- record values of a parameter of operation of the flow metering system over a predetermined initialization time interval of operation of the flow metering system;
- determine reference values for the parameter based on the recorded values;
- a parameter verification engine configured to:
- apply the reference values to values of the parameter acquired after the initialization time interval to validate operation of the flow metering system.
