FMC Technologies Venturi Tubes are manufactured to comply with the exact needs of the client. Venturi Tubes are available in long and short form, depending upon accuracy requirements. Venturi Tubes are virtually maintenance free as there have no internal seals or moving parts. They can be used to measure a wide variety of applications such as air, gas, vapor, liquid, steam, sludge and slurry.

FMC Technologies Venturi meters are the right choice when specialized flow measurement is required. Custom designed and engineered to cover a wide range of applications and measurement needs, FMC's Venturi Tubes provide accurate, economical and efficient flow measurement with minimal permanent pressure loss. While they are primarily used in low static line pressure applications where high-pressure recovery is essential, FMC's Venturi Tubes are ideal for measurement of viscous flows and flows containing suspended solids.

Benefits:

• Maintenance free - no moving parts
• Mounted through any angle (vertical or horizontal)
• Can be used to measure a variety of mediums
• High-pressure recovery and low permanent pressure loss
• Available in 2" to 60" sizes (larger sizes available upon request)
• Available in a variety of standard and exotic materials
• Meets all ISO 5167-4 and ASME MFC-3M industry specifications and tolerances
• Short and long form (15° or 7° convergent cone) options
• Cast, machine bar or rolled plate versions available
• Discharge accuracy of ±1%

Accuracy:

Each FMC Venturi Tube has a coefficient of discharge accuracy of ±1% though greater accuracy can be obtained by calibrating the Venturi Tubes in a test laboratory. FMC Technologies Measurement Solutions will calibrate the Venturi meters at the customer's request. 

FMC's Venturi Tubes have wide range capability and will operate down to 200,000 pipe Reynolds number. Laboratory flow calibrations below 200,000 pipe Reynolds number are recommended

Measurement Standards:

FMC Ventruri Tubes are manufactured in strict accordance with the latest editions of:

• ISO 5167-4.2003
• ASME MFC-3M:2004
