2 Product Summary Venturi F L O W M E T E R I N G E Q U I P M E N T ® Racine Flow Meter Group SSL – Classical (Herschel) Design The Classical Venturi Flow Meter is designed in accordance to ISO 5167. Process Connections: NPT, Flanged, Butt Weld, Socket Weld, Grooved Instrument Connections: NPT, Socket Weld, Flanged Accuracy: ±1% of reading uncalibrated Available as an insert design; model VISSL Standard beta ratios: 0.35, 0.49, 0.63 and 0.70; exact sizing available to provide custom beta ratios SSM – Hydraulic Shape Design (Nozzle Type) The hydraulic pure static design utilizes the proven ASME-MFC-3M standard for the highest accuracy, predictability, and repeatability. The flow conditioning generated by the unique hydraulic shape will provide an extremely stable signal in a wide range of flows. Process Connections: NPT, Flanged, Butt Weld, Socket Weld, Grooved Instrument Connections: NPT, Socket Weld, Flanged Accuracy: ±1-2% of reading uncalibrated Available as an insert design; model VISSM Standard beta ratios: 0.35, 0.49, 0.63 and 0.70; exact sizing available to provide custom beta ratios LPL – Low-Loss Design (Short Form) The low permanent pressure loss design with over 35 years of proven field performance in a wide variety of applications provides reduced operating costs. Low installation costs due to short laying length and the wide range of sizes and material of construction make the LPL the right choice for many flow applications. Process Connections: NPT, Flanged, Butt Weld, Socket Weld, Grooved Instrument Connections: NPT, Socket Weld Accuracy: ±3-5% of reading uncalibrated Available as an insert design; model VILP PRESO, ELLIPSE and COIN are registered trademarks of Racine Federated Inc. © 2008 Racine Federated Inc., all rights reserved Form No. 4-25-33 5/08 Printed in USA 8635 Washington Avenue Racine, WI 53406-3738 USA Tel: 262-639-6770 Fax: 262-417-1148 Toll Free: 800-632-7337 E-mail: info@preso.com Preso Venturi flow meters are differential pressure flow devices providing highly accurate (up to ±1% of reading uncalibrated, ±0.5% calibrated) and repeatable (±0.1% of reading) measurements of liquids, gases, and steam. The Venturi restricts the flow at its throat and measures the pressure difference of the unrestricted flow and restricted flow. The Venturi's throat can be designed to meet the flow measurement application optimizing the Venturi's accuracy and permanent pressure loss. The Preso Venturi's design provides longer lasting accuracy and lower permanent pressure loss than orifice type meters, reducing maintenance and operating costs. The Preso Venturi can be built to meet the highest pressure and temperature specifications often limited in other flow meter technologies. All models can also be supplied with RTDs and transmitters to provide an economical mass flow measurement solution.
