Calibration of Flow Meters
Almost each type of flow meter application requires its own calibration procedure. Therefore quite a lot of information is needed before running a calibration. Examples of questions we would like to ask before calibrating your meter are;
- What type of meter is it?
- What liquid is it operating in?
- How is it used (continuous, batching, installation)?
- What accuracy is needed?
On instruments with multiple output signals we also prefer to know what signal (like frequency, mA or field bus) is used during normal operation. This is of course due to the fact that different outputs have different measuring errors.
Calibration interval
"How often do we need to recalibrate" is a very common question. There are really no general answers, but among factors that have to be considered are operating environment, media, meter type, requested uncertainty and how the meter is used.
SP calibration capabilities
In our flow laboratory we have a number of different liquids available, including cold and hot water, petroleum products and alcohol. Flow rates range from droplets to approximately 720 cubic meter per hour. Our laboratory resources in detail are listed under the links "in laboratory" and "in field" below.
