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.
Technical Parameters
Applicable Environments
1. Industries: Urban gas distribution, industrial boilers, chemical plants, and
commercial gas billing (e.g., restaurants, hotels).
2. Gases: Natural gas, biogas, propane, nitrogen, and other non-corrosive
gases
Conditions:
Temperature: -30°C to +60°C (environmental), -10°C to +60°C (gas media).
Humidity: 5%–90% RH (non-condensing).
No straight pipe requirements for installation, suitable for compact spaces.
Key Advantages
1. High Accuracy & Wide Rangeability: Maintains ±1.5% accuracy across a 20:1 to 243:1 flow range.
2. Low Startup Flow: Starts measuring at 0.03–0.1 m³/h (minimal flow detection).
3. Energy-Efficient: Micro-power design with 3.6V battery (5-year operation).
4. Smart Features: IoT integration for remote monitoring, prepaid systems, and leak
detection.
