Dosch - Model MBL 500 - Meter Runs Inlet and Outlet Piping
Meter runs combine inlet and outlet piping with a flow element which is used for flow measurement of single phase aggressive and non-aggressive gases, steam or liquids, especially for small pipe diameters up to DN 50 (2'). Due to the integrated in- and outlet pipes flow disturbances can be reduced.
For steam and gas measurements we can include additional taps in the inlet and outlet for pressure and temperature compensation.
In small pipelines the influence of flow disturbances on the measurement is significant. Our inlet and outlet pipes are manufactured to fulfill all requirements which are defined in the calculation standards. This ensures minimum measurement uncertainties. Additionally, the major part of the necessary inlet and outlet pipe length is already included in our design.
Ranges from 0,5% -1,5% of the discharge coefficient C, depending on the application
The pressure loss depends on the diameter ratio p (d/D) and ranges from 30 - 80% of the differentia pressure.
