Product Description
Product Description
E+H 84F Coriolis Mass Flowmeter
In the landscape of industrial process measurement, the demand for accurate, reliable, and durable flow measurement solutions has never been more critical. Industries ranging from oil and gas to pharmaceuticals, food and beverage, and chemical processing rely on precise flow data to optimize processes, ensure product quality, and comply with stringent regulatory standards. Endress+Hauser (E+H), a global leader in measurement instrumentation, automation, and solutions for industrial process engineering, has consistently addressed this demand with innovative products. Among its flagship offerings, the E+H 84F Series Coriolis Mass Flowmeter stands out as a benchmark for precision, versatility, and robustness.
Before delving into the specifics of the E+H 84F, it is essential to grasp the fundamental principle underlying Coriolis mass flowmeters—one of the most accurate technologies for direct mass flow measurement.
The Coriolis effect, named after the French mathematician Gaspard-Gustave de Coriolis, describes the apparent deflection of a moving object in a rotating reference frame. In the context of flow measurement, this effect is harnessed by inducing vibration in a flexible measuring tube through which the fluid flows.
When no fluid is flowing, the tube vibrates symmetrically around its natural frequency. As fluid enters the vibrating tube, it is forced to accelerate toward the point of maximum vibration (antinode) and decelerate as it moves away. This acceleration and deceleration create opposing Coriolis forces on either side of the tube's vibration axis, causing the tube to twist. The degree of twist is directly proportional to the mass flow rate of the fluid: higher flow rates result in greater twist, while lower flow rates produce minimal deflection.

1. Product Overview of the E+H 84F Series
The E+H 84F Series is a family of Coriolis mass flowmeters engineered for industrial applications requiring high precision, reliability, and adaptability. Developed based on decades of E+H's expertise in flow measurement, the 84F Series combines advanced sensor technology with intuitive electronics to deliver consistent performance in harsh and demanding environments.
1.1 Positioning and Design Philosophy
The 84F Series is positioned as a mid-to-high-range industrial flowmeter targeting applications where accuracy and durability are non-negotiable. Its design philosophy centers on three core principles
Precision by Design: Every component, from the measuring tube to the signal processing unit, is optimized to minimize measurement error.
Robustness for Harsh Environments: Constructed with materials resistant to corrosion, abrasion, and extreme temperatures/pressures.
1.2 Core Components
The E+H 84F Series comprises three integral components: the sensor unit, the transmitter, and the auxiliary accessories.
1.2.1 Sensor Unit
The sensor is the "heart" of the 84F Series, responsible for generating the Coriolis effect and detecting tube deflection. Key features include:
Measuring Tube: Available in stainless steel 316L (for general applications), Hastelloy C-276 (for corrosive fluids), or titanium (for high-purity or aggressive media). The tube is precision-machined to ensure consistent vibration characteristics and minimal hysteresis.
Detectors: Two piezoelectric sensors mounted on either side of the measuring tube to detect vibration and measure the phase shift caused by Coriolis forces.
1.2.2 Transmitter
The transmitter processes signals from the sensor, calculates mass flow rate, density, and temperature, and presents the data to the user or integrates it with control systems. The 84F Series offers two transmitter options:
Integrated Transmitter: Mounted directly on the sensor for space-constrained applications. Features a backlit LCD display, four-button keypad, and local configuration capabilities.
Remote Transmitter: Installed up to 100 meters from the sensor (using shielded cables) for applications where the sensor is in a harsh or inaccessible location. Offers enhanced connectivity and advanced diagnostics.

2. Structural Design and Material Selection
The durability and performance of the E+H 84F Series are heavily influenced by its structural design and material choices, which are tailored to withstand the challenges of industrial environments.
2.1 Measuring Tube Design
The measuring tube is the most critical component of the sensor, as its vibration characteristics directly impact measurement accuracy. The 84F Series uses a single-tube or dual-tube design (depending on the model):
Dual-Tube Design: Common in mid-to-high flow models (84F30, 84F40), this design uses two parallel tubes that vibrate in opposite directions. The dual-tube configuration minimizes external vibration interference and provides greater mechanical stability.
Single-Tube Design: Used in low-flow models (84F10, 84F20) to optimize sensitivity for small flow rates. The tube is reinforced with a support structure to maintain vibration consistency.
Both designs feature a U-shape or straight-tube geometry. U-shaped tubes offer higher sensitivity (ideal for low flow rates), while straight-tube designs provide minimal pressure loss (suitable for high-flow, high-pressure applications).
2.2 Material Selection for Harsh Environments
E+H selects materials for the 84F Series based on the fluid compatibility and process conditions:
Measuring Tube:
Hastelloy C-276: Used for corrosive media (e.g., acids, alkalis, seawater). Resistant to pitting, crevice corrosion, and stress corrosion cracking.
Titanium: Ideal for high-purity applications (e.g., pharmaceuticals, semiconductor manufacturing) and aggressive fluids (e.g., chlorine, bromine). Provides superior corrosion resistance and biocompatibility.
Housing:
Aluminum Alloy: Used for standard enclosures, offering a balance of strength and weight.
Seals and Gaskets:
2.3 Hygienic and Sanitary Design (Optional)
For food, beverage, pharmaceutical, and biotech applications, the 84F Series offers a hygienic variant designed to meet 3-A Sanitary Standards and FDA requirements:
Smooth Internal Surfaces: Ra < 0.8 μm (32 μin) finish on the measuring tube to prevent product buildup and facilitate cleaning.
Tri-Clamp Connections: Easy-to-disassemble connections for rapid cleaning-in-place (CIP) and sterilization-in-place (SIP) procedures.
