8 CAUSES OF DWYER FLOW METER CALIBRATION DRIFT

8 CAUSES OF DWYER FLOW METER CALIBRATION DRIFT

Like most flow meters, Dwyer flow meters have one major requirement: calibration. It is vital to ensure you re-calibrate your meter on a frequent basis – this will ensure your flow meter is functioning accurately. Without frequent calibration, it is likely that you will face the consequences of calibration drift.

Dwyer flow meter calibration drift causes your instrument to improperly read measurements; therefore, causing a domino effect of negative risks. These risks could include inaccuracy, unreliability, and a loss in finances. To avoid these risks, frequent calibration of a Dwyer flow meter is highly encouraged.

CAUSES OF FLOW METER CALIBRATION DRIFT

When a regular calibration schedule has been created and followed, causes of Dwyer flow meter calibration drift minimize. Common causes of calibration drift include:

  • Deposits on internal surfaces of the Dwyer flow meter
  • Flow meter wearing due to chemicals
  • Negligence and misuse of a Dwyer flow meter
  • The age of the flow meter
  • Changes of fluid properties within the Dwyer flow meter
  • Improper installation of the flow meter
  • Improper usage of a Dwyer flow meter for a particular job
  • Environmental influences, including temperature and humidity

These factors, along with periodic use, also help to determine how frequently your Dwyer flow meter should be calibrated. A calibration schedule should be based on a Dwyer flow meter’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, Dwyer flow meters are known to be highly accurate and reliable instruments. To uphold its reputation, it is important to ensure you have set a regular calibration interval you’re your instrument. Not only does frequent calibration of a Dwyer flow meter reap many benefits, but it can also provide optimized performance and longevity!
