Flow limit The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.
The optimum flow velocity is between 2 to 3 m/s (6.56 to 9.84 ft/s). Also match the
velocity of flow (v) to the physical properties of the fluid:
• v < 2 m/s (6.56 ft/s): for abrasive fluids (e.g. potter's clay, lime milk, ore slurry)
• v > 2 m/s (6.56 ft/s): for fluids producing buildup (e.g. wastewater sludge)
A necessary increase in the flow velocity can be achieved by reducing the sensor
nominal diameter.
For an overview of the full scale values for the measuring range, see the "Measuring
range" section →  147
For custody transfer, the applicable approval determines the permitted measuring
range.
Pressure loss • No pressure loss occurs if the sensor is installed in a pipe with the same nominal
diameter.
• Pressure losses for configurations incorporating adapters according to DIN EN 545
