Product Description

E+H Promag W300

In the dynamic landscape of industrial process control, accurate and reliable flow measurement is the cornerstone of efficient operations, quality assurance, and resource management. Endress+Hauser, a globally recognized leader in industrial automation and measurement technology, has been at the forefront of developing innovative solutions to meet the diverse and evolving needs of various industries. Among its extensive range of cutting - edge flow measurement instruments, the Proline Promag W300 electromagnetic flowmeter stands out as a high - performance device designed to address the complex challenges of modern industrial processes.
The Promag W300 is engineered with precision and built to endure harsh industrial environments while delivering accurate and stable measurements of conductive fluid flow. Whether it is deployed in water and wastewater treatment plants, chemical processing facilities, or food and beverage manufacturing lines, this electromagnetic flowmeter has proven to be a reliable and versatile solution. This in - depth technical article will explore the working principle, key features, performance specifications, installation and maintenance requirements, as well as the wide range of applications of the Endress+Hauser Proline Promag W300 electromagnetic flowmeter.

1. Key Feature

1.1 High Accuracy and Precisio
The Promag W300 is renowned for its exceptional measurement accuracy, which is essential for critical process control and quality management. It typically achieves an accuracy of ±0.2% of the measured value, ensuring that the volumetric flow rate of the fluid is determined with a high degree of precision. This accuracy is maintained over a wide range of flow rates, from low - flow applications where precise dosing is required to high - flow scenarios in large - scale industrial pipelines.
The high precision of the Promag W300 is the result of a combination of advanced manufacturing techniques, high - quality components, and sophisticated signal processing algorithms. The precise calibration of the measuring tube, magnetic coils, and electrodes, along with the use of advanced digital signal processing in the transmitter, enables the flowmeter to deliver accurate and repeatable measurements, even in the presence of varying process conditions.
1.2 Wide Rangeability
One of the significant advantages of the Promag W300 is its wide rangeability, allowing it to accurately measure flows over a broad spectrum of values. With a typical rangeability of up to 1000:1, the flowmeter can handle both very low - flow rates, such as those encountered in laboratory experiments or the injection of small amounts of additives, and high - flow rates in large - scale industrial processes.
This wide rangeability eliminates the need for multiple flowmeters in applications where the flow rate varies significantly, simplifying the process design and reducing installation and maintenance costs. It also provides flexibility in process operation, enabling seamless adaptation to changing production demands without sacrificing measurement accuracy.
1.3 Low Pressure Drop
The Promag W300 features a streamlined and obstruction - free design of the measuring tube, resulting in a very low pressure drop across the flowmeter. This is a crucial advantage, especially in applications where energy efficiency is a priority and where the fluid is pumped through the system. A low pressure drop means that less energy is required to move the fluid through the flowmeter, leading to reduced operating costs, lower wear and tear on pumping equipment, and improved overall process efficiency.

2. Performance Specifications

2.1 Measuring Ranges
Volumetric Flow: The volumetric flow measurement range of the Promag W300 varies depending on the size of the measuring tube. It can measure volumetric flows from as low as a few liters per hour to several thousand cubic meters per hour. For example, in smaller - sized models with a tube diameter of 10 mm, the volumetric flow range may be 0 - 0.2 m³/h, while in larger models with a tube diameter of 1200 mm, the range can reach up to 0 - 6785 m³/h. This wide range of measurement capabilities makes the Promag W300 suitable for applications across various industries, from small - scale laboratory setups to large - scale industrial production and distribution systems.
Flow Velocity: The flowmeter can accurately measure flow velocities in the range of 0.01 m/s to 15 m/s. This broad velocity range allows it to handle different fluid flow conditions, whether it is slow - moving fluids in mixing tanks or high - velocity flows in pipelines, ensuring accurate measurement across a wide variety of industrial processes.
2.2 Pressure and Temperature Ratings
Process Pressure: The Promag W300 is designed to operate at different process pressures, depending on the model and application requirements. The maximum process pressure rating can be up to PN 400, Class 2500, or 400 bar. This high - pressure capability makes it suitable for use in high - pressure applications such as high - pressure chemical reactions, oil and gas pipelines, and industrial steam systems, where the ability to withstand high pressures is essential for reliable operation.
Media Temperature: The standard media temperature range for the Promag W300 is typically - 20 °C to +180 °C (- 4 °F to +356 °F). However, for applications involving extreme temperatures, special versions of the flowmeter can be configured with appropriate materials and insulation to extend the temperature range. In high - temperature applications in the petrochemical industry, for example, the flowmeter can be designed to handle media temperatures up to +250 °C (+482 °F), while in low - temperature applications such as cryogenic fluid measurement, it can be adapted to operate at lower temperatures as well.
