Promass 83F / 84F Coriolis Mass Flowmeter

Overview

The Promass 83F / 84F is Endress+Hauser’s flowmeter with premium accuracy, robustness, and extended transmitter functionality, delivering the highest measurement performance for liquids and gases under varying, demanding process conditions. The Promass 84F variant is specifically designed for custody transfer applications, featuring worldwide-recognized metrological approvals, while the 83F offers extended transmitter functionality with software for filling and dosing, density and concentration measurement, and advanced diagnostics.

As an authorized supplier of Endress+Hauser instrumentation, Seven Star LLC proudly offers the Promass 83F / 84F to oil and gas, chemical, and custody transfer facilities across the Sultanate of Oman, Muscat, and the wider GCC. Its multivariable measurement capability—simultaneously capturing mass flow, density, and temperature—reduces the number of process measuring points required at any given installation.

Measurement Principle

The Promass 83F / 84F operates on the Coriolis measuring principle, which functions independently of physical fluid properties such as viscosity and density. Mass flow measurement error reaches ±0.05% with PremiumCal calibration, with standard accuracy of ±0.1% for liquid mass flow and volume flow, and ±0.35% for gas mass flow, while density measurement achieves ±0.0005 g/cm³ accuracy.

The balanced two-tube measuring system provides insensitivity to vibrations, while the robust design remains immune from external piping forces, allowing installation without accounting for inlet and outlet straight-run requirements—a significant space-saving advantage over other flow measurement technologies. Measuring ranges extend up to 2,200,000 kg/h (80,840 lb/min), covering everything from precision dosing applications to high-volume custody transfer metering.

Engineering Design of the Promass 83F / 84F

The Promass 83F / 84F covers nominal diameters from DN 8 to 250 (3/8″ to 10″), with high-temperature versions available in DN 25 (1″), DN 50 (2″), and DN 80 (3″). Standard medium temperature range spans -50°C to +200°C, extending to -50°C to +350°C in high-temperature configurations, with pressure ratings up to PN 100, Class 600, or 63K depending on the connection standard.

The transmitter features a 4-line backlit display with touch control, operable from outside the enclosure, and is available in compact or remote versions with IP67, Type 4X protection. Four modular outputs (0/4-20mA, pulse/frequency/switch, relay) and two modular inputs support flexible system integration, with digital communication available via HART, PROFIBUS PA/DP, FOUNDATION Fieldbus, Modbus RS485, and EtherNet/IP.
