Rosemount™ 3051SFC Compact Orifice Flow Meter
Featuring multivariable measurements in a single device, the Rosemount 3051SFC Compact Orifice Flow Meter delivers accurate flow measurements.
Built with either a compact orifice plate, a patented 4-hole conditioning plate, or averaging pitot tube, this flow meter provides measurements for closed loop control, general purpose monitoring and custody transfer applications. Available in line sizes up to 12 in. (300 mm), this primary element is designed for gas, liquid and steam service and operates well in harsh process conditions. 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®.
