3051SFC with unique serial number 5000339 is an integrated compact orifice flow transmitter under Emerson Rosemount 3051S high-performance platform. This all-in-one assembly combines premium 3051S high precision differential pressure sensing module with pre-calibrated integral orifice primary element, eliminating separate field installation of orifice plate and impulse piping. It is specially designed for inline flow measurement of liquid, gas and steam media, widely applied in petrochemical, thermal power and oil & gas industries for small-bore pipeline flow custody measurement and process flow control.

Adopting SuperModule high-stability sensing core, the unit converts differential pressure generated by throttling effect into standard electrical signal with digital communication function. Factory pre-assembly and overall calibration effectively reduce field installation error and leakage points caused by on-site piping work. Built-in comprehensive intelligent diagnostic system continuously monitors sensor status, internal flow passage blockage and electrical loop fault to cut unplanned maintenance and unexpected production shutdown. Each finished unit completes strict factory hydraulic calibration and tightness inspection for direct onsite startup after pipeline mounting.

Reference accuracy reaches up to ±0.025% of full calibrated span; overall installed flow performance is controlled within ±0.10% full scale. Maximum adjustable turndown ratio hits 200:1 for flexible onsite range modification without hardware replacement. Five-year long-term stability is kept within ±0.0625% of calibrated span under continuous long-cycle operating condition.

Standard output is 4–20mA analog signal superimposed with HART7 digital communication protocol, supporting remote parameter configuration via handheld communicator or DeltaV DCS control system. Optional communication selections include FOUNDATION Fieldbus H1, PROFIBUS PA and WirelessHART based on customized order requirement. Conventional loop-powered HART transmitter runs on supply voltage ranging from 10.5VDC to 42.4VDC.

Default process-contacting components including integral orifice and isolating diaphragm adopt 316L stainless steel. Alternative corrosion-resistant options such as Hastelloy C-276, Monel alloy are available for corrosive medium and NACE sour service working environment. Transmitter housing is die-cast aluminum with anti-corrosion epoxy coating, and high-performance dedicated fill fluid is equipped inside sensing module.

Ambient operating and storage temperature both range from -40℃ to +85℃; applicable relative humidity is between 5% and 95% under non-condensing surroundings. Allowable process medium temperature is subject to fill fluid and body material configuration.

Optional backlit local LCD supports on-site real-time instantaneous flow reading and zero & span trimming operations. Body-mounted push buttons enable field calibration without extra auxiliary testing instruments. Advanced onboard diagnostics cover flow passage clogging detection, signal loop integrity monitoring and sensor drift early warning.

This compact flow transmitter obtains SIL2/SIL3 functional safety certification complying with IEC61508 standard, together with ATEX and FM explosion-proof approvals for installation in classified hazardous locations, covered under Emerson five-year limited factory warranty.

Inline flow measurement of small-diameter process pipelines, feed flow control for chemical reactor auxiliary lines, water and compressed air flow monitoring for power plant auxiliary system, and gas pipeline small-bore flow metering for oil & gas production facilities.
