iDroset CSD Factory Testing and Calibration

Every iDroset CSD is 100% factory tested to a minimum accuracy of +/- 10% as per industry standard. Using the master meter method of flow measurement calibration, two Model ASAMG signal converters (+/- 0.5% accuracy) are used to establish the reference flow on the test stand to which the iDroset direct read-out is compared. The flow accuracy is measured at four points within the flow range rating of the model being tested.

Samples that do not pass the test are recalibrated by a factory technician and tested again. No iDroset leaves the factory until it meets the +/- 10% accuracy standard.
