Abstract
A flowmeter method and system. In an implementation, a signal is received from a flowmeter and a value is determined based on the signal. The value is compared to a threshold. A heartbeat value is provided when the value is greater than a threshold value. In some implementations, a flow rate of a fluid is based on the heartbeat value. In some implementations, the heartbeat value is monitored and an alarm is selectively generated based on the monitoring.
Claims36
A method, comprising:
- receiving a signal from a flowmeter, the flowmeter being responsive to a fluid flow through the conduit;
- determining a value based on the signal;
- comparing the value to a threshold;
- providing a heartbeat value when the value is greater than the threshold;
- and
- determining a flow rate of the fluid flow based on the heartbeat value;
- wherein the threshold is indicative of a boundary between a liquid region and a gas region of the fluid flow.

A system, comprising:
- a flowmeter;
- one or more processors in communication with the flowmeter;
- and
- a computer-readable storage medium coupled to the one or more processors having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations, comprising:
- receiving a signal from a flowmeter, the flowmeter being responsive to a fluid flow through the conduit;
- determining a value based on the signal;
- comparing the value to a threshold;
- providing a heartbeat value when the value is greater than the threshold;
- and
- determining a flow rate of the fluid flow based on the heartbeat value;
- wherein the threshold is indicative of a boundary between a liquid region and a gas region of the fluid flow.
