Flow measurements are absolutely necessary when it comes to assess the hydraulic conditions of sewage networks or special constructions.
The importance of portable, power-independent flow meters for determination of infiltration, channel efficiency, sewerage master planning or influent control is hence continuously rising. Reliable and significant data representing typical operational conditions of the measurement places are to be gained with the help of these data.
It is very often required to carry out the measurements only for a few weeks or months to obtain representative data.
A measurement system for portable flow measurements basically consists of a transmitter Type PCM for power supply, data entry, indication and data storage plus a sensor for the recording of measurement data.
Sensor construction as well as the built-in pickups may be customised individually according to the conditions prevailing on site.
For flow velocity measurement starting at flow levels as low as 3 cm up to several meters there is a wide selection of sensors available.
