Endress+Hauser Promass 80F Coriolis Mass Flowmeter

Overview

The Endress+Hauser Promass 80F is a robust Coriolis mass flowmeter engineered for demanding applications where process fluids swing in temperature, pressure, or composition. It delivers highest-performance measurement of liquids, gases, and steam from a single sensor, combining mass flow, density, and temperature output with a pressure-rated sensor housing built to handle the harshest conditions found in process plants.

As the official authorized partner and exclusive regional representative for Endress+Hauser, Seven Star LLC proudly supplies the Endress+Hauser Promass 80F to industrial facilities across the Sultanate of Oman and the wider GCC, backed by genuine factory calibration, full documentation, and local technical support.

Measurement Principle

The Endress+Hauser Promass 80F operates on the Coriolis measuring principle. Process fluid is directed through a pair of curved measuring tubes driven into oscillation at their natural resonant frequency; as mass flows through the vibrating tubes, the Coriolis force creates a measurable phase shift between the tube legs that is directly proportional to mass flow rate, while the resonant frequency itself shifts in proportion to fluid density.

Because this measurement derives from the physical inertia of moving mass rather than an inferred volumetric relationship, it remains stable under fluctuating pressure, temperature, and viscosity. There are no moving parts to wear, no flow obstruction to create pressure drop, and no requirement for upstream or downstream straight-run piping, which keeps the Promass 80F accurate even through the process upsets common on aging or high-throughput plant assets.

Engineering Design of the Endress+Hauser Promass 80F

The sensor uses a pressure-rated housing certified to PN 100 / Class 600 / 63K and a measuring tube available in 1.4539 (904L), 1.4404 (316/316L), or corrosion-resistant Alloy C22 (2.4602 / UNS N06022), covering nominal diameters from DN 8 to DN 250 (3/8 inch to 10 inch), with dedicated high-temperature variants at DN 25, DN 50, and DN 80. The sensor housing itself is built from corrosion-resistant 1.4301/1.4307 (304L) stainless steel.

The transmitter is available in compact (sensor-mounted) or remote configurations, with a 2-line backlit local display and push-button interface for on-site diagnostics and configuration, fully compliant with IEC/EN/NAMUR standards. This flexibility allows the Promass 80F to be installed where vibration, heat, or access constraints make a sensor-mounted transmitter impractical.

Key Features

The Endress+Hauser Promass 80F is built for demanding process duty where accuracy has to hold under stress, and the Endress+Hauser Promass 80F remains a proven workhorse across upstream and downstream applications:

• Delivers mass flow accuracy of ±0.15% standard, improving to ±0.1% with the calibration option.
• Withstands process pressures up to PN 100 / Class 600 / 63K with a pressure-rated sensor housing to 40 bar.
• Measures mass flow, density, temperature, volume flow, corrected volume flow, and reference density from one device.
• Covers a measuring range from 0 to 2,200,000 kg/h across its DN 8 to DN 250 nominal diameter range.
• Handles medium temperatures from –50°C to +350°C in the high-temperature variant.
• Available with compact or remote transmitter mounting to suit site access and vibration constraints.
• Requires no inlet or outlet straight-run piping, saving space on tightly packed skids.
• Offered in corrosion-resistant wetted materials including 904L stainless steel and Alloy C22 for aggressive media.

Industrial Applications

The Endress+Hauser Promass 80F is specified for refineries, petrochemical plants, gas processing facilities, and steam metering applications where process conditions vary widely and mass-based accuracy is critical to custody transfer and mass balance accounting. Its pressure-rated housing and wide temperature range also suit upstream oil and gas duties, high-pressure chemical dosing, and heavy industrial processing lines.
