2.3.4Flow range limits

The reference condition flow range limits for SeniorSonicTM Meters (pipe sizes from 100 mm to 900 mm) are listed in the appendix tables (see Appendix F).

Daniel should be consulted before establishing the actual meter capacity for a particular application.

The meter capacity at reference (base) conditions of pressure and temperature may be calculated as shown in Equation 2-1.
