The Endress+Hauser Proline I300 Thermal Mass Flowmeter stands at the forefront of gas flow measurement technology, offering unparalleled accuracy, reliability, and versatility for industrial applications. Designed by Endress+Hauser-a global leader in process automation and instrumentation-the Proline I300 combines advanced thermal mass flow sensing with intelligent signal processing to deliver precise, real-time measurements of gas flow rates, even in challenging environments. With its robust construction, innovative features, and comprehensive communication capabilities, this flowmeter is engineered to optimize processes, reduce energy consumption, and ensure compliance with strict industry standards across diverse sectors, including chemical, pharmaceutical, food and beverage, power generation, and environmental monitoring.
At the heart of the Proline I300 lies thermal dispersion technology, which measures gas mass flow based on the principle that heat transfer from a heated sensor to a flowing gas is proportional to the mass flow rate. Unlike volumetric flow meters that require temperature and pressure compensation, the Proline I300 provides direct mass flow measurement, eliminating the need for additional sensors and complex calculations. This results in simplified system design, reduced installation costs, and enhanced measurement accuracy (up to ±0.5% of reading + 0.2% of full scale).The flowmeter's sensor consists of two platinum resistance temperature detectors (RTDs): one is heated, while the other measures the gas temperature. The power required to maintain a constant temperature difference between the two sensors is directly proportional to the mass flow rate. This technology enables highly sensitive measurements, even for low-flow or low-pressure applications, making the Proline I300 ideal for monitoring gas consumption, leak detection, and process control.
Features
Insertion or Inline Configurations: The Proline I300 is available in both insertion-style (for large pipes or ducts) and inline-style (for smaller pipes) versions, offering flexibility for various installation requirements.Wide Measuring Range: With a turndown ratio of up to 100:1, the flowmeter accurately measures gas flows from near-zero to maximum rates, accommodating dynamic process conditions.High-Temperature Resistance: The sensor can withstand process temperatures up to 400°C (752°F), making it suitable for applications involving hot gases or steam.Corrosion-Resistant Materials: Options include stainless steel, Hastelloy, or titanium sensors, ensuring compatibility with corrosive gases such as hydrogen sulfide or chlorine.Multi-Variable Output: In addition to mass flow, the Proline I300 provides temperature and pressure outputs (when equipped with optional sensors), enabling comprehensive process monitoring.
Digital Signal Processing (DSP): Advanced algorithms filter out noise and fluctuations, ensuring stable and reliable measurements even in turbulent flow conditions.
Product Overview
The Endress+Hauser Proline I300 Thermal Mass Flowmeter combines cutting-edge thermal technology with intelligent design to deliver precise, reliable gas flow measurements across diverse industrial applications.
