Although Agilent offers a handful of different flow meters ranging from single use meters to standard flow meters, each model has a common requirement: calibration. No matter what Agilent meter you own, it is crucial to re-calibrate your meter on a frequent basis. Regular calibration ensures the overall accuracy of the instrument.
Many individuals ask “when is the right time to calibrate my flow meter?” The answer to this question is not exactly simple, however, in this article we will discuss what causes flow meters to drift and how to incorporate these factors into a calibration schedule.
CAUSES OF FLOW METER DRIFT
Common reasons flow meter drift include:
- The presence of deposits on internal surfaces of the meter.
- Wearing from chemicals.
- Misuse and negligent care of the flow meter.
- The age of the flow meter itself.
- Fluid property changes within the flow meter.
- Incorrect installation of the meter.
- Using the wrong meter for a particular job.
- External influences such as, temperature, pressure and vibration
These factors, along with periodic use, are what determine how frequently a flow meter should be calibrated. A calibration schedule should be based on Agilent’s manufacturer recommendation (varies for model type), the amount you use the instrument and if any of the above factors apply to the meter.
When cared for properly, Agilent flow meters are known to be highly accurate and reliable instruments. This is why it is important to ensure the instrument is always living up to its great reputation. Frequent calibration of this instrument reaps many benefits and can provide optimized performance and longevity!
