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 LogTrans-field data logger.

Application areas

  • Customized weir to calculate the water flow with the water level
  • Water level probe available with measuring ranges from 30 cm water column on and up to 0.1 mm resolution
  • can be used in spring captures and other small surface waters


  • Applicable under difficult hydraulic conditions
  • Water level sensors with 0.1 mm resolution available and thus even applicable for very low discharges
  • Can be combined with Camera K1 for visual observation of the current situation
  • Energy self-sufficient by accumulator service
