Rosemount™ 3051SFP Integral Orifice Flow Meter
The Rosemount 3051SFP Integral Orifice Flow Meter is a no-equal multivariable device customized with an integral orifice primary element.
This meter run assembly provides easy installation and is engineered to facilitate highly accurate flow measurement in small line sizes (0.5 - 1.5 in. or 15 - 40 mm). This device is also engineered with built-in flow calculations for fully compensated mass flow measurements and is offered with multiple communication protocols including WirelessHART®.
