Requirements for the use of pipe measurement sections
Flanges have to be welded from the outside and possibly existing weld seams on the inside must be smoothened.
Flanges and sealings must not reach into the inside of the pipe measurement section.
The nominal inside dimensions of the used pipes and slide valves must correspond exactly.
Please observe the minimum distance between sensor surface and maximum water level if external ultrasonic measurement is used. This distance is 30 cm (11.8 in) for the P06/P10 and 12.5 cm (4.9 in) for the P03 depending on the sensor used. Pipe measurement sections with dome top available from NIVUS are designed for these requirements up to a preliminary pressure of 10 m (30 ft) water column.
In case of higher preliminary pressures we recommend to use a pipe measurement section completely made of stainless steel (please request separately).If you use pipe measurement sections not supplied by NIVUS we recommend a technical inspection by our expert personnel prior to use. Please submit revealing drawings or dimensioned sketches with your request.

In case of existing applications with large pipes (e.g. concrete or plastic) we often are able to offer low-cost special solutions in order to minimize constructional expenses so that there is no need to install a separate pipe measurement section. Please ask for our experiences and special solutions while you are planning your application.
