The intelligent gas waist wheel (Roots) flow meter is a new generation of flow meter that integrates the detection functions of flow, temperature and pressure, and can automatically compensate for temperature and pressure. Gas is a compressible fluid, and its volume value is closely related to temperature and pressure.
Working principle
Intelligent gas waist wheel (Roots) flowmeter is mainly composed of shell, conjugate rotor, counter and intelligent flow totalizer and other components. A pair of conjugate rotors installed in the metering chamber keep the correct relative position of the rotors through precision-machined adjustment gears under the action of the inlet and outlet pressure difference (P in > P out) of the circulating gas.
Features
High-performance Hardware
Built with advanced microcomputer technology and high-performance integrated chips, using SMT circuits for strong anti-interference, high reliability, and compliance with international standards. All units undergo high/low temperature aging and vibration testing.
Compact Integrated Design
Pressure, temperature, and flow sensors are all built-in, ensuring a compact and highly integrated structure.
Ultra-low Power Consumption & Long Battery Life
Micro-power design supports both built-in battery (over 5 years of operation) and external power supply, adapting to various power scenarios.
Comprehensive Intelligent Functions
Equipped with self-diagnosis and alarm functions, plus a clear, intuitive LCD display. Supports RS485 communication to form remote meter reading networks for centralized data collection and real-time management.
Reliable Data Security
Uses E2PROM storage to prevent data loss during battery replacement or sudden power outages; internal parameters are permanently saved under power failure.
Rich Display & Signal Output
High-contrast 3-line LCD shows date, standard cumulative/instantaneous flow, medium temperature, pressure, and battery voltage. Multiple signal outputs meet different site and system requirements.
Automatic Temperature & Pressure Compensation (Intelligent Model Only)
Detects gas temperature, pressure, and flow rate in real time, automatically compensates flow and corrects compression factors, and displays cumulative flow under standard conditions (Rs=101.325kPa, Ts=293.15K).
