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.

Pressure loss
• No pressure loss occurs as of nominal diameter DN 8 (3/8") if the sensor is installed in a pipe with
the same nominal diameter.
• Pressure losses for configurations incorporating adapters according to DIN EN 545 →  39
System pressure
A0028777
Never install the sensor on the pump suction side in order to avoid the risk of low pressure, and thus
damage to the liner.
Furthermore, install pulse dampers if reciprocating, diaphragm or peristaltic pumps are used.

Vibrations
In the event of very strong vibrations, the pipe and sensor must be supported and fixed.
