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).
A necessary increase in the flow velocity can be achieved by reducing the sensor
nominal diameter.
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
