Your data is only as good as it is calibrated. Below is a link to a video that shows the calibration methods use for open-channel sensors. We perform regular calibration of all sensing equipment, including pipe flow and climatic sensors.
It is part of SWIIM’s quality assurance process – once delivery and water balance reports are received, data is crossed-checked again to be sure that anomalies are non-existent – as data is processed near-real-time. Finally, as the conclusion of the season, an audited report is produced. Data credibility is key when it comes to tracking crop water usage, especially today.
