Measurement of capacity and intensity of drainage water

Figuring out how to continuously measure the capacity of drainage water that run out from ameliorative tubing was very interesting for us. The problem was that the measurement should be in several shaft rings in which were not any sharp crested weirs ever. So, our company developed special kind of sharp crested weirs which is customised for each measured place. In some shaft rings are sometimes placed two of this sharp crested weirs.
