Intelligent Gas Roots (Waist Wheel) Flow Meter
The Intelligent Gas Roots (Waist Wheel) Flow Meter is a volumetric flow meter designed for precise measurement of gases (e.g., natural gas, inert gases). It utilizes a dual-rotor (waist wheel) mechanism to calculate flow by counting rotations proportional to gas volume. Key features include:
1. Smart Compensation: Integrated temperature and pressure sensors automatically correct volume to standard conditions (e.g., Nm³), ensuring accuracy under varying conditions.
2. IoT Connectivity: Supports RS485 communication, pulse output, and remote data transmission for real-time monitoring and prepaid management systems.
3. Display: Shows instantaneous flow, cumulative flow, temperature, pressure, and battery status.
