8705 — Rosemount 8705 Electromagnetic Flow Transmitter
The Rosemount 8705 Electromagnetic Flow Transmitter paired with the 8711/8712 sensor forms Emerson's highest-accuracy electromagnetic flowmeter system for water and conductive liquid measurement across Saudi Arabia's utility and industrial sectors. Certified to OIML R49 and Saudi SASO standards for fiscal water metering, the 8705/8711 combination achieves ±0.2% accuracy for NWC water supply custody transfer and SWCC desalination product distribution measurement. The system's dual-frequency excitation at 11.75 Hz and 75 Hz eliminates flow noise from slurry and coating conditions without compromising signal strength in Saudi Arabia's low-conductivity water sources.
The 8705's Multivariable Digital output simultaneously transmits flow velocity, totalizer, and conductivity readings to NWC's SCADA system, enabling real-time water quality verification alongside flow measurement without separate conductivity analyzers. Smart Meter Verification (SMV) technology performs automated in-situ meter health checks without process interruption, generating calibration confidence records that satisfy Saudi water authority audit requirements without meter removal. The transmitter's sealed aluminum housing with corrosion-resistant coating withstands the humid coastal conditions at SWCC's Red Sea and Arabian Gulf desalination plants.
For NEOM smart city water infrastructure, the 8705's WirelessHART option connects to IoT-enabled metering networks without dedicated cable infrastructure, reducing NEOM city installation costs. The flowmeter's HART-enabled multivariable output connects to NEOM's centralized city management platform for predictive infrastructure maintenance analytics. Emerson's AMS (Asset Management Suite) software integration tracks meter performance trends over time, enabling NEOM utility operators to plan maintenance before meter failure occurs.
Razz Middle East provides complete 8705/8711 electromagnetic flowmeter systems including sensor conditioning units, grounding rings, and installation hardware for Saudi utility project packages. Our flow measurement specialists support NWC and Marafiq procurement teams with meter selection, hydraulic sizing, and installation drawing preparation for smart meter district replacements across Saudi cities.
