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.

Approvals, Functional Safety, and Hazardous-Area Certification
The Endress+Hauser Promass F300 carries an unusually broad certification portfolio for a single device family, with explosion-protection approvals under ATEX, IECEx, cCSAus, NEPSI, INMETRO, EAC, and UK Ex, which allows a single instrument standard to be applied across multinational project scopes without re-engineering the hazardous-area design for each jurisdiction. Functional safety is addressed through compliance with IEC 61508, making the device applicable in safety instrumented functions designed to IEC 61511 – relevant for overfill protection, burner management fuel metering, and emergency shutdown interlocks common in Omani refining and gas processing facilities.
For commercial measurement, the flowmeter is available with custody transfer approvals including MI-005 and MI-002 under the European Measuring Instruments Directive, PTB certification, and NTEP for North American loading applications, with factory calibration carried out to ISO/IEC 17025. Hygienic variants are certified to 3-A and EHEDG and are supplied in line with cGMP expectations, covering dairy, beverage, and pharmaceutical duties. Process pressure ratings extend to PN 100, Class 600, and 63K, and the sensor housing is supplied in 1.4301 (304) as standard or 1.4404 (316/316L) as an option, with the transmitter housing available in coated AlSi10Mg, cast 1.4409 (CF3M), or stainless steel for aggressive plant atmospheres.
Transmitter Interface, Outputs, and Commissioning
The transmitter of the Endress+Hauser Promass F300 presents a four-line backlit display with touch control that can be operated through the closed cover, so a technician does not have to open the enclosure – and therefore does not have to obtain a hot-work or gas-test permit – simply to read a totaliser or acknowledge a diagnostic message. An optional WLAN interface allows the same menu structure to be reached from a laptop, tablet, or phone through a standard web browser, which is a practical benefit when the meter is installed at height on a pipe rack or inside a congested skid. A remote display version is available where the sensor location is genuinely inaccessible.
The device provides up to three configurable outputs, selectable between 4–20 mA HART, WirelessHART, passive 4–20 mA, pulse/frequency/switch, double pulse for phase-shifted counting, and relay, together with status and 4–20 mA inputs for bringing in an external pressure or temperature signal for live compensation. Supply options cover 24 V DC and 100 to 230 V AC, and the enclosure is rated IP66/67 Type 4X with IP69 available for high-pressure washdown areas. Ambient operation is specified from −40°C to +60°C as standard, with a −50°C low-temperature option; the upper limit should be respected when siting the transmitter in direct Gulf sunlight, and Seven Star LLC routinely recommends a sunshade or the remote-mount version for unshaded outdoor installations in Oman.
