Venturi Meters • Classical - Insert - Short Form ASME/ISO Standards
Performance Specifications
• Suitable for pipe sizes from:
1/2"(13mm) to 48"(1200mm)

• Integral transmitter mount 3 or 5 valve manifold
(Option - IT3V)

• Mass flow measurements with dynamic process
compensation for pressure, temperature and DP with
multivariable transmitter

• End connections:
- Threaded (1/2" to 3")
- Insert Types (4" to 30")
- Butt-weld and flanged
(up to 2500psi/165 Bar)

• Insert styles are designed to be installed between
existing flanges (Series 200)

• Low Permanent Pressure Loss (PPL). High energy
savings, low pumping costs (1/3 of orifice plate)

• Design Standards: ASME/MFC-3M,ISO-5167,
ANSI B31.1 and BS-7045

• Materials: CS, SS, Alloy 20, Chrome Moly, Monel,
Hastelloy, Duplex SS, etc.
