How does an oil flow meter work ?
How to calibrate oil flow meter ?
Flow meter calibration is the process of comparing the pre-set scale or metering of a flow meter to a standard scale of measurement. And adjusting its metering to conform to the standard. Calibration is an essential aspect of instrumentation in a broad range of industries that require high-accuracy measurements with a negligible percentage of error.
E.g. in Oil & Gas, Petrochemical, and manufacturing.
Generally, there are two types of flowmeter calibration: online calibration and offline calibration.
On-line calibration does not need to remove the flow meter to achieve the calibration under the online flow state. This method is not very accurate, but calibration can probably be performed with an ultrasonic flow meter.
The other is off-line calibration. This method has high accuracy, but the flowmeter must be removed for calibration by the manufacturer, or brought to the metrology institute for calibration.
Flow meters are calibrated by comparing and adjusting their metering to correspond with a predefined standard. Flow meter manufacturers typically calibrate their products in-house after production or send them to an independent calibration facility for adjustment.
