Measures to avoid device vibrations (L > 10 m (33 ft))
Adapters
Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor
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.
The nomogram only applies to liquids with a viscosity similar to that of water.
1. Calculate the ratio of the diameters d/D.
2. From the nomogram read off the pressure loss as a function of flow velocity
(downstream from the reduction) and the d/D ratio.

Length of connecting cable
To ensure correct measuring results when using the remote version,
observe the maximum permitted length of the connecting cable L
max
. This length is
determined by the conductivity of the fluid.
If measuring liquids in general: 5 µS/cm
