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 media (e.g. cleaning agents)
• v > 2 m/s (6.56 ft/s): For media that produce buildup (e.g. liquids containing oil and
sugar)
A necessary increase in the flow velocity can be achieved by reducing the sensor
nominal diameter.

range" section → 59
Pressure loss
• For DN 8 (5/16"), DN 15 (½") and DN 25 (1") 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
