Measuring weir – Discharge measurements in spring captures

This measurement system, with a high-precision water level probe, allows the determination of the discharge in spring captures. For this purpose, the water level in the weir is measured with high accuracy and the discharge is calculated. The measurement system is compatible with the LogTrans6-digi-GPRS data logger.
