Proline Promag 55 FOUNDATION Fieldbus
108
Hauser
Pressure tightness Promag S in US units [psia = pounds/inch²]
Pressure tightness Promag H (Measuring tube lining: PFA)
Limiting flow
Further information can be found in the "Nominal diameter and flow rate" section
Pressure loss
• No pressure loss if the sensor is installed in piping with the same nominal diameter (for Promag H
only from DN8).
• Pressure losses for configurations incorporating adapters according to DIN EN 545
