Features
Performance Specifications
Features
• For Liquid and Gas flow measurements.
Pipe sizes from: 1/2”(13MM) to 2-1/2″(64MM)
• Integral Transmitter Mount 3 or 5 valve manifold
(IT3V-Option)
• Mass Flow Measurement with dynamic process
compensation for pressure, temperature and DP with
multivariable transmitter
• End connections:
– Threaded and Flanged Type
(150#, 300#, 600#, & 900#) or Higher Ratings
• Low pressure losses (High energy savings),
low pumping costs (1/3 of orifice plate)
• Design Standards: ASME/MFC-3M, ISO-5167,
ANSI B31.1 and B31.3
• Materials: Standard 316SS
Others: Per request
