In industrial settings where precise monitoring of gas flow is critical—such as in energy management, chemical processing, or environmental reporting—accuracy is paramount. The Actual Mass Flow Meter has become an essential instrument for providing reliable, direct measurement without the need for complex corrections. This article provides a detailed look at the LEOMI-587, a prominent example of this technology, explaining its operation, key features, and suitable applications based on its technical specifications.
What is an Actual Mass Flow Meter?
A mass flow meter is a precision instrument designed to measure the mass flow rate of a gas or liquid moving through a system. Unlike volumetric flow meters, an Actual Mass Flow Meter measures the mass rate directly. This is crucial because mass, unlike volume, does not change with temperature or pressure. This direct measurement provides highly reliable data for process control, safety, and custody transfer, making it a cornerstone tool in industries like manufacturing, chemicals, and pharmaceuticals.
Introducing the LEOMI-587 Actual Mass Flow Meter
The LEOMI-587 is a recent innovation in thermal mass flow technology. It is an insertion-style meter designed as a reliable solution for measuring both mass and volumetric flow in various applications.
Core Technical Features and Specifications
The design and capabilities of the LEOMI-587 are defined by several features:
⭐ Direct Measurement: It measures the actual mass flow (and volumetric flow), with a high turndown ratio of 100:1 or greater.
⭐ High Accuracy and Range: It offers an accuracy of better than ±2% of reading and is suitable for pipe sizes ranging from 15 mm to 10,000 mm.
⭐ Durable Construction: The sensor probe is available in materials like Stainless Steel and Hastelloy C276, with options for coatings like HALAR® or PFA for corrosive environments. Probe lengths can extend up to 2000mm.
⭐ High-Temperature Operation: This Actual Mass Flow Meter is trusted for precise measurement in temperatures up to 400°C.
⭐ Smart Functionality: It includes a built-in auto-cleaning system for the sensor and data logging capabilities via USB 2.0, storing parameters in CSV format.
⭐ Flexible Integration: The device supports up to 4 user-configurable analog inputs for parameters like pressure or temperature and is well-suited for custom flow control applications via PC software.
Primary Industrial Applications
Due to its reliability and adaptability, the LEOMI-587 serves multiple core sectors:
✔️ Power Generation: Monitoring combustion air and flue gases in thermal power plants.
✔️ Heavy Industry: Process control in steel, cement, and textile plants.
✔️ Automotive & Manufacturing: Managing ventilation and oven processes in paint shops.
✔️ Chemical & Pharmaceutical: Precise measurement of process and reaction gases, critical for safety and quality in chemical, fertilizer, and drug manufacturing.
How It Works: The Thermal Measurement Principle
The LEOMI-587 operates on the thermal dispersion principle. It has a heated sensor and a temperature sensor. As gas flows past, it carries heat away from the heated sensor. The amount of cooling is directly proportional to the actual mass flow of the gas. This method allows for a direct mass flow reading without needing separate sensors for pressure and temperature.
Conclusion
The LEOMI-587 Actual Mass Flow Meter represents a significant tool for industrial efficiency and control. By offering direct mass flow measurement, high accuracy, durability in harsh conditions, and intelligent features, it provides a dependable solution for complex industrial challenges. Selecting such an instrument is an investment in process reliability, safety, and operational data integrity.
