Product Description

Endress+Hauser Proline Prowirl 72F DN25 Vortex Flow Meter

The Endress+Hauser Proline ProWirl 72F DN25 is a high-performance vortex flowmeter engineered for precise and reliable measurement of gas, vapor, and liquid flow in industrial applications. Designed with advanced sensor technology and robust construction, this device delivers accurate volumetric flow data across a wide range of process conditions, making it ideal for use in energy management, chemical processing, oil and gas, and steam distribution systems. Its versatility, combined with minimal maintenance requirements, ensures long-term operational efficiency while reducing lifecycle costs.

Measurement Principle and Performance The ProWirl 72F operates on the vortex shedding principle, leveraging the Karman vortex street effect to determine flow velocity. As process media passes a bluff body in the flowmeter, vortices are generated at a frequency proportional to the flow rate. A piezoelectric sensor detects these vortices, converting them into a digital signal for highly accurate measurements. The DN25 (1-inch) model is optimized for applications requiring precise monitoring of low to mid-range flow rates, with turndown ratios up to 30:1 and repeatability of ±0.1%. It maintains accuracy even under fluctuating process conditions, such as varying temperatures (-40°C to +250°C) and pressures (up to 16 bar), ensuring dependable performance in demanding environments.

Material and Construction Crafted from high-grade stainless steel (1.4404/SS316L), the ProWirl 72F offers exceptional corrosion resistance and mechanical durability, suitable for aggressive media like steam and hydrocarbons. The device features a compact, spool-piece design with no moving parts, minimizing pressure loss and eliminating wear-related issues. Its IP67-rated housing ensures protection against dust and water ingress, while optional hazardous area certifications (ATEX, IECEx, FM) enable safe deployment in explosive atmospheres. The sensor's integrated digital signal processing enhances stability in vibrating environments, common in industrial piping systems.

Communication and Integration The ProWirl 72F supports multiple communication protocols, including HART, PROFIBUS PA, and FOUNDATION Fieldbus, enabling seamless integration into modern control systems. Real-time flow data, diagnostics, and configuration parameters can be accessed via Endress+Hauser's FieldCare software or local display modules. Advanced diagnostic functions provide early detection of process anomalies, such as cavitation, vibration, or media changes, reducing unplanned downtime. The device also supports partial stroke testing and NAMUR-compliant alarms for proactive maintenance.

Installation and Maintenance Designed for ease of installation, the DN25 model fits standard ANSI, DIN, and JIS piping configurations. The lack of moving parts minimizes the need for routine calibration or component replacement, lowering total cost of ownership. Its self-cleaning design prevents media buildup, ensuring consistent performance in liquid or gas applications. For steam measurement, the meter complies with EN 1434-1 standards, making it suitable for energy billing and boiler efficiency monitoring.

Applications The ProWirl 72F DN25 is widely used in industries requiring precise flow measurement of saturated or superheated steam, natural gas, liquefied petroleum gas (LPG), water, solvents, and light hydrocarbons. Key applications include custody transfer, boiler feedwater monitoring, flare gas measurement, and process optimization in refineries and chemical plants. Its ability to operate without straight pipe inlet runs (with optional flow conditioners) simplifies retrofitting into existing systems.
