Flow recording in an open channel using the Parshall flume according to iso 9826

The use of the DL2/DL7 data logger, Parshall flume and ultrasonic probe enables measurement of volumetric flow in an open channel. The datalogger calculates the flow based on the height of the medium (measured by the probe) and entered math formula. The data recorded by the DL2/DL7 data logger enable analysis of the system operation and are a confirmation of the operating conditions. In application note is a description of using the DL2 data logger to calculate and monitor flow in an open channel.
