Sierra instruments are known for being robust and reliable, but is important to remember that even the most robust instruments, especially flow meters, can fall out of calibration and drift. Drifting of Sierra instruments can occur for many reasons, but flow meters are especially prone to drifting caused by their environmental surroundings. Corrosion and dirt are known to be the number one cause of flow meter calibration drift. Because it is not possible to control the environment in which you place a flow meter, it is of utter importance to ensure you are calibrating your flow meter regularly and properly. Proper calibration is needed to ensure accuracy and reliability.
Watch the brief video below to assist you in best practices for Sierra flow meter calibration.
