Roots Flowmeter: High-Precision Gas Flow Measurement
The Roots Flowmeter is a positive displacement meter renowned for its exceptional accuracy and reliability in measuring the flow of clean, dry gases. Operating on the principle of two precisely machined, counter-rotating "Roots" impellers, it traps and displaces a fixed volume of gas with each revolution. This mechanical action is translated into a precise digital pulse output, providing highly repeatable and accurate flow data. As a cornerstone technology in gas flow measurement, it is the preferred choice for critical applications in fiscal metering, custody transfer, and process control where measurement integrity is paramount.
Key Features & Advantages
Unmatched Accuracy: Delivers exceptionally high measurement accuracy (e.g., ±0.5% to ±1.0%) across a wide flow range, making it ideal for custody transfer and fiscal metering where every unit of gas counts.
Wide Flow Rangeability: Offers an excellent turndown ratio (e.g., 10:1 or higher), ensuring precise measurement from low to high flow rates within a single meter.
Proven Durability & Long Service Life: Constructed with robust materials and a simple, mechanical design with no metal-to-metal contact, ensuring long-term stability and reduced wear.
Minimal Pressure Drop: The impellers are designed to rotate freely, creating a very low permanent pressure loss, which enhances overall system efficiency.
Pulse Output for Direct Reading: Generates a precise pulse signal directly proportional to the displaced gas volume, enabling easy integration with flow computers, PLCs, and SCADA systems for direct totalization and flow rate calculation.
Excellent Repeatability: The positive displacement principle guarantees that the same volume of gas is displaced for each revolution, providing highly consistent and repeatable results.
