Endress+Hauser Promass F300 Coriolis Mass Flowmeter

Overview

The Endress+Hauser Promass F300 is a premium-accuracy Coriolis mass flowmeter built for process industries where measurement integrity directly affects product quality, custody transfer accounting, and regulatory compliance. It simultaneously measures mass flow, volume flow, density, concentration, and temperature from a single sensor, a hallmark of the Endress+Hauser Promass F300 design, removing the need for separate instruments at the same measuring point and reducing both installation cost and potential leak paths.

As the official authorized partner and exclusive regional representative for Endress+Hauser, Seven Star LLC proudly supplies the Promass F300 to process plants, refineries, and manufacturing 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 F300 operates on the Coriolis effect: process fluid is split and directed through a pair of curved measuring tubes that are driven into oscillation at their natural frequency. As mass flows through the vibrating tubes, the Coriolis force induces a measurable phase shift between the inlet and outlet legs of each tube that is directly proportional to mass flow rate, while the resonant frequency of oscillation shifts in proportion to fluid density.

Because the measurement is derived from the fundamental physics of moving mass rather than an inferred or volumetric relationship, it is inherently immune to changes in pressure, temperature, viscosity, or fluid conductivity. There are no moving parts to wear, no obstruction to create pressure drop, and no dependency on upstream or downstream straight-run piping, which keeps installation compact and measurement uncertainty low even in demanding process conditions.

Engineering Design of the Endress+Hauser Promass F300

The sensor houses a symmetrical dual-tube measuring system in stainless steel 1.4539 (904L), 1.4404, or corrosion-resistant Alloy C22 (2.4602 / UNS N06022), selected to match the process medium and covering nominal diameters from DN 8 to DN 250 (3/8 inch to 10 inch). The rugged sensor housing is rated for the harshest ambient conditions typically found on process plants and offshore platforms in the Gulf region.

The transmitter is a compact, easily accessible unit that can be mounted directly on the sensor or remotely on a wall or panel, with a backlit local display for on-site diagnostics and configuration. Communication options include HART, PROFIBUS, Modbus, EtherNet/IP, and Ethernet-APL, and every unit ships with Heartbeat Technology for continuous self-verification and predictive diagnostics without process interruption.

Key Features

The Endress+Hauser Promass F300 combines premium accuracy with engineering robustness in a single compact package:

• Delivers mass flow measurement error as low as ±0.05% with the PremiumCal calibration option, among the tightest tolerances available in Coriolis metering.
• Measures up to seven process variables simultaneously – mass flow, volume flow, corrected volume flow, density, reference density, concentration, and temperature.
• Requires no inlet or outlet straight-run piping, saving space in tightly packed skid and pipe-rack installations.
• Handles medium temperatures from –196°C to 350°C, suiting both cryogenic and high-temperature process duties.
• Includes Heartbeat Technology for continuous device self-verification traceable to national standards.
• Available in measuring tube materials rated for corrosive and hygienic service, including 904L stainless steel and Alloy C22.
• Supports HART, PROFIBUS, Modbus, EtherNet/IP, and Ethernet-APL for direct integration into modern process control systems.
• Immune to fluctuating pressure, temperature, and viscosity, maintaining accuracy through upset and transient process conditions.

Industrial Applications

The Endress+Hauser Promass F300 is specified wherever mass-based accounting and product quality depend on precise flow data: custody transfer skids, chemical dosing and blending lines, refinery and petrochemical units, cryogenic LNG handling, and food, beverage, and pharmaceutical production where hygienic accuracy and traceability are non-negotiable. The Endress+Hauser Promass F300’s multivariable output also makes it a natural fit for concentration monitoring in liquid analytics and density-critical batching processes.

As the officially authorized partner for Endress+Hauser, Seven Star LLC distributes the Promass F300 to industrial and process facilities throughout Oman and the GCC, including projects in the Sohar and Salalah economic zones, district cooling and desalination plants, and the oil and gas sector’s upstream and downstream operations, all supported by regional stock availability and factory-trained technical staff.
