Abstract
A meter calibration system and apparatus capable of calibrating meters devoid of process connections. The apparatus are a calibration system and process connection adapters, where in the system is operable for calibrating both linear and nonlinear meters at multiple flow rates, and is suitable for use with both gravimetric and master meter standard references.
Claims31
A meter calibration system configured to calibrate a meter devoid of process connections, comprising:
- process connection adapters for connecting the meter under test to the calibration system;
- a source for flowing a process material through the calibration system and meter;
- an apparatus that generates measurement signals in response to said material flow;
- and
- a controller configured to process measurement signals derived from the calibration system and the meter to derive calibration information.
A method of calibrating a meter under test devoid of process connections, the method comprising the steps of:
- connecting a first process connection adapter to an input of said meter and a second process connection adapter to an output of said meter to form a series connection with said meter;
- flowing serially through said first process connection adapter, said meter, and said second process connection adapter;
- generating measurement signals in response to said flow;
- and
- processing measurement signals to derive calibration information for the meter.
A process connection adapter, comprising
- a first end portion configured to connect to a meter devoid of process connections;
- a second end portion configured to connect to a calibration system;
- and
- an intermediate portion for transitioning said first end portion to said second end portion.
A method of fulfilling an order placed by a customer, the method comprising the steps of:
- producing a meter devoid of process connections;
- calibrating said meter in a calibration system capable of calibrating a meter devoid of process connection;
- processing a customer order;
- and
- attaching process connections based on customer order.
