Field test systems

For the flow measurement in sewer systems there is a wide variety of measuring systems available. These enable us to record flow velocity as well as water level with the help of ultrasound, radar, bubbling, pressure probes and magnetic-inductive methods.

• continuous logging of precipitation as point measurements
• Recording of duration, time and intesity of the rain events

These probes are used for simultaneous, continuous recording of up to seven parameters in bodies of water. The data is stored in a data logger.

The record the basic data for dirt freight calculations, the COD (chemical oygen demand) is required as the primary input variable. With our COD probes it is possible to record continuous hydrographs of COD using the UV measuring method. Alternatively, samplers in combination with analysis in the laboratory are available.

For the design of infiltration systems, precise knowledge of the kf value is required. With the help of a double ring infiltrometer or an open-end-test, the infiltration capacity of the subsoil can be determined.
