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.
