Gas turbine flow meters are velocity-type flow instruments, often referred to as the “high-performance speedometer” of gas measurement. Their operating principle is as follows: as fluid flows through the meter, it drives a precision turbine rotor to rotate.

Deskripsi
Product Advantages:
The core value of gas turbine flowmeters lies in their unquestionable precision, exceptional reliability, and cost-effectiveness for large-scale flow measurement.
- Trade-grade high accuracy: With accuracy classes as high as ±1.0% R or even higher, it serves as one of the legal metering instruments for natural gas trade settlement, ensuring fair transactions while minimizing measurement disputes and economic losses.
- Wide Turndown Ratio: Features an exceptionally wide turndown ratio, typically reaching 1:20 or even 1:30, maintaining accuracy across extremely low to high flow ranges. This makes it ideal for applications with significant fluctuations in gas demand.
- Excellent Repeatability: Exhibits minimal repeatability error (typically better than ±0.2%), ensuring consistent results under identical conditions. This delivers reliable and trustworthy data.
- Rapid Response: Responds swiftly to flow changes, accurately capturing pulsating gas flows and rapid flow variations, making it suitable for process control requiring fast response.
- Integrated Intelligent Temperature and Pressure Compensation: Built-in temperature and pressure sensors enable direct output of volumetric or mass flow at standard conditions (20°C, 101.325 kPa), eliminating the need for external transmitters and simplifying system architecture.
- Digital Communication and Diagnostics: Supports pulse and 4-20mA outputs while integrating protocols like HART and MODBUS. Enables remote data retrieval, instrument self-diagnostics, and condition monitoring for predictive maintenance.
Core Application Areas:
- Natural Gas Trade Settlement: Trade metering at city gas gate stations, transmission and distribution networks, and industrial energy entry points (compliant with international standards such as OIML R137 and EN12261).
- Industrial Gas Monitoring: Cost accounting and energy consumption management for plant utility gases including compressed air (CFA), nitrogen (N₂), oxygen (O₂), and argon (Ar).
- Gas Pressure Regulation & Metering Stations: Core instrumentation for regional metering or large-user measurement.
- Energy Management & Carbon Accounting: Provides precise gas consumption data for ISO 50001 energy management systems and carbon footprint calculations.
Laboratories & Test Facilities: Serves as a standard meter for calibrating other gas flow meters.
