  RBC flumes are used to measure quantities of water. Compared to familiar flumes such as the WSC or Parshall flumes, RBC flumes give the most accurate results. The RPC flume has been especially designed for use in small streams (irrigation, inflows and discharges, furrows etc.). It is a simple and reliable instrument for measuring water volume that flows onto a field as irrigation. The standard range includes flumes with different measurement ranges of between 0.1–8.7 l/s and 2.0–145 l/s.
  Larger measurement ranges can also be covered on request. The essential condition for obtaining precise measurement results is that the flume be erected absolutely horizontally and that water can flow onto the flume and out of the flume without obstruction. The value of the increased water level can be read off on the measurement equipment (measuring cylinder) at the end of the measurement flume. The flow rate (discharge rate) is calculated using standard formulae. A pressure sensor can also be installed and connected to a data logger instead of reading measurements off the measuring cylinders. This enables automatic measurement (and activation), storing and reading. In the case of an automated flume, the threshold value of the water level is recorded using an extremely accurate pressure sensor connected to a data logger.
