SSL-Classical Design (Hershel) Product Data Sheets

Venturi Flow InstrumentationModel SSLVEN-DS-00792-EN-02 (May 2014) Product Data SheetDESCRIPTIONThe Venturi Model SSL (Classical Venturi Design) is a Hershel/Classical design differential pressure flow device.CONFIGURATIONThe Venturi inlet section is cylindrical with a pressure sensing tap the same diameter as the incoming pipe section. The tap is followed by a precise convergent section that causes a uniform change in fluid velocity. The cylindrical throat section with a pressure sensing tap, straight section and the exit cone has a precise angle in order to prevent permanent pressure loss that does not exceed 12% of the generated differential pressure. The beta ratio is determined by the manufacturer according to recognized standards and formulas. The discharge coefficient (Cd) is linear and stable in the operating flow range, has a value above 0.985 and is achieved by adhering to the ASME standards.MATERIALSThe construction material, instrument connections, instrument valves and end connections are selected to meet the intended service conditions. Identification tag is provided as required.QUALITYAll Venturi meters are manufactured under an ISO 9001:2008 certified quality program. Certification documentation is available for inspection. The manufacturer will provide a Flow Calculation Data Sheet with standard data and formulas for approval by the design engineer.APPLICABLE FLUIDSLiquids, gases and steam.ACCURACY & REPEATABILITYThe accuracy of the flow element is within ±1.0% uncalibrated (±0.5% calibrated) with a repeatability of ±0.1% and turndown of 10:1 in the corresponding and appropriate range of Reynolds’ Numbers. For custody transfer applications, the Venturi is wet flow tested by an independent NIST certified laboratory under the design operating conditions and piping configurations.www.badgermeter.comPRESO is a registered trademark of Badger Meter, Inc.
