Abstract
A method and apparatus is disclosed that guides a user through a sequence of steps that will allow the user to complete a predefined task using the flow meter. The steps include: selecting a predefined task, displaying a sequence of steps that directs the user through a process for using the Coriolis flow meter to complete the predefined task, and operating the Coriolis flow meter in response to the sequence of steps to complete the predefined task.
Claims15
A method, comprising:
- selecting a predefined task to be completed using a Coriolis flow meter, wherein the predefined task is verification of a flow calibration factor for the Coriolis flow meter;
- prompting a user to select a material with a known density;
- prompting the user to select a required accuracy for the Coriolis flow meter;
- determining a density deviation from the known density that corresponds to the required accuracy;
- directing the user to introduce the material into the Coriolis flow meter;
- measuring the density of the material using the Coriolis flow meter;
- comparing the measured density with the known density;
- and
- when the measured density is different than the known density by more than the density deviation, alerting the user that an error condition exists.

A system, comprising:
- a Coriolis flow meter;
- a computer system, including a display, connected to the Coriolis flow meter;
- a Coriolis control module, running on the computer system, where the Coriolis control module is configured to control the Coriolis flow meter;
- a Coriolis guru module, running on the computer system, configured to communicate with the Coriolis control module;
- the Coriolis guru module configured to prompt a user to select a predefined task to be completed using the Coriolis flow meter, wherein the predefined task is verification of a flow calibration factor of the Coriolis flow meter, and display a sequence of steps that directs the user through a process for using the Coriolis flow meter to complete the predefined task, wherein the sequence of steps comprise:
- prompting a user to select a material with a known density;
- prompting the user to select a required accuracy for the Coriolis flow meter;
- determining a density deviation from the known density that corresponds to the required accuracy;
- directing the user to flow the material through the Coriolis flow meter;
- measuring a density of the material using the Coriolis flow meter;
- comparing the measured density with the known density;
- and
- when the measured density is different than the known density by more than the density deviation, alerting the user that an error condition exists.
