Fluid temperature
Conductivity ≥ 5 μS/cm for liquids in general. Stronger filter damping is required for very low
conductivity values.

The necessary minimum conductivity also depends on the cable length .

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 low conductivity values
• v > 2 m/s (6.56 ft/s): for fluids producing buildup (e.g. milk with a high fat content)
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 →  207
Pressure loss • No pressure loss occurs as of nominal diameter DN 8 (5/16") if the sensor is installed in
a pipe with the same nominal diameter.
• Pressure losses for configurations incorporating adapters according to DIN EN 545
