Determination of reference values for ultrasonic flow metering systems

摘要

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.
