Product Description
Introducing the exceptional High-Performance Gas Turbine Flow Meter, engineered for precise and reliable measurements that ensure accuracy in every application.
Our products are meticulously produced and certified, adhering strictly to the JG 1037-2008 Turbine Flowmeter Verification Procedure and the GB/T21391-2008 National Standard for measuring natural gas with gas turbine flowmeters, guaranteeing you the highest standards of quality and compliance.
Discover the next generation of precision metering with our newly developed gas turbine flowmeter. This state-of-the-art instrument combines the best of aviation technology with principles of fluid mechanics and electromagnetism to deliver unmatched accuracy and reliability. Featuring integrated temperature, pressure, and flow sensors, along with an intelligent flow integrator, it excels in both low and high-pressure environments. With diverse signal output options and minimal fluid disturbance sensitivity, it is perfect for natural gas, coal-to-gas, liquefied gas, and hydrocarbon gas applications. Crafted with cutting-edge CNC processing, it boasts a robust structure, exceptional durability, superior repeatability, and effortless installation.
At Jiangsu Hualiu Instrument Co., Ltd., we are committed to delivering high-reliability products. During R&D, we performed extensive durability tests in collaboration with leading bearing manufacturers to ensure the utmost reliability of bearings and structural components. Our integrated movement design ensures top-tier product reliability, reducing your after-sales concerns and providing peace of mind.
1. Experience minimal pressure loss, typically ranging from 0.1 to 2.5kPa under standard conditions, to ensure efficient operation.
2. Benefit from our high-accuracy measures across the full range at 1% - 2.0%, with high-precision options offering 0.5% - 1.0% accuracy, positioning us as a leader in precision measurement.
3. With its compact design and lightweight build, our flowmeter guarantees easy installation and handling, while offering substantial circulation capacity.
4. Enjoy superior repeatability, ranging from 0.05% to 0.2%, making it an ideal choice for trade settlements due to its consistent performance.
5. Achieve a wide range with large calibers reaching 20:1 or more, and small calibers at 10:1, coupled with a low starting flow rate for versatile application.
6. Customize your display with multiple options, from a simple mechanical counter to a sophisticated flow totalizer with temperature and pressure compensation. Long-term lithium battery power ensures convenient, uninterrupted use.
7. The pulse frequency signal output is perfect for total quantity measurement and seamless computer connectivity, offering zero drift and strong seismic resistance. High-frequency signal output options provide excellent signal resolution, reaching 3-4kHz.
8. Our flow meter's strong reliability stems from using magnetic induction or photoelectric sensors for signal detection, featuring rapid response times and built-in self-inspection for stability across various challenging environments.
As fluid enters, it is expertly rectified and accelerated by a dedicated rectifier at the air inlet. The turbine, angled against the flow, generates torque, overcoming friction and resistance to rotate. This rotation speed is directly proportional to the fluid's volume flow rate. Using electromagnetic induction, a magnetic sensor detects a pulse signal matching the flow rate, which is processed by our intelligent flow totalizer. The results are clearly displayed on the LCD screen, offering real-time volume flow rate and total gas measurement.
