Rosemount 4088 MultiVariable Transmitter

The Rosemount 4088 MultiVariable Transmitter is Emerson's solution for comprehensive flow measurement in a single field device, simultaneously measuring differential pressure, static pressure, and process temperature to calculate mass flow rate without a flow computer. For Saudi Aramco gas custody transfer applications regulated by Saudi OGRA (Oil and Gas Regulatory Authority) and Saudi Aramco's Revenue Accounting System, the 4088 reduces the instrument count per flow measurement point from three separate transmitters plus a flow computer to a single device, cutting installation and calibration costs. The transmitter achieves AGA-7 and AGA-3 gas flow calculation accuracy for Saudi Arabia's natural gas allocation metering applications.

The 4088's three-variable measurement capability enables accurate mass flow calculation for Saudi Aramco's gas gathering systems where pressure and temperature conditions vary significantly across different collection points. The transmitter corrects differential pressure for static pressure and temperature effects in real-time, eliminating the systematic errors that occur when separate instruments provide asynchronous measurements. For SABIC's steam metering applications, the 4088 calculates quality-corrected steam mass flow using simultaneous temperature and pressure measurement, enabling accurate energy billing in Jubail's central utilities.

With WirelessHART communication, the 4088 enables retrofit gas flow measurement at Saudi Aramco remote gathering points where cable installation would be prohibitively expensive. The transmitter's battery-powered wireless option provides 5 years of operation without maintenance, ideal for Saudi Aramco's unmanned wellhead measurement and remote pipeline offtake points in the Rub' al Khali desert. WirelessHART gateway integration connects field measurements directly to Saudi Aramco's central data historians in Dhahran for real-time gas allocation accounting.

Razz Middle East supplies 4088 MultiVariable transmitters with gas flow calculation coefficients pre-programmed for Saudi Arabia's dominant gas compositions — methane-rich pipeline gas, heavier gas liquids-rich separator gas, and sour gas streams. Our metrology engineers support Saudi Aramco's gas measurement group with orifice plate sizing, Reynolds number correction verification, and AGA-3/AGA-7 compliance documentation for OGRA submission.
