Flow limit The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.
The optimum velocity of flow 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.

range" section →  176
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
