If possible, install the sensor well clear of assemblies such as valves, T-pieces, elbows etc.
The following inlet and outlet runs must be observed in order to meet accuracy specifications:
• Inlet run ≥ 5 × DN
• Outlet run ≥ 2 × DN
Inlet and outlet run
Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor Promag D
as wafer version in larger-diameter pipes. The resultant increase in the rate of flow improves
measuring accuracy with very slow-moving fluids. The nomogram shown here can be used to calculate
the pressure loss caused by reducers and expanders.
Note!
• Adapters can not be used for Promag D with threaded connection.
• The nomogram only applies to liquids of viscosity similar to water.
The pressure loss is calculated as follows:
1. Calculate the diameter ratio: d/D
2. Read off the pressure loss (as a function of flow velocity (downstream from the reduction) and
the d/D ratio from the nomogram)
