Ideal for applications involving natural gas, city gas, propane, nitrogen, and various industrial inert gases, the Intelligent Gas Roots Flowmeter is engineered to provide unparalleled measurement precision and operational excellence.CHARACTERISTIC 1. Expansive Measurement Range:Depending on the selected specifications, the flowmeter offers a staggering maximum range of 1:216, with a remarkably low starting flow: 2. The minimum starting flow can be as low as 0.04m3/h, tailored to specific specifications. 3. Superior Precision and Consistency:Achieving long-term measurement stability, this flowmeter maintains its accuracy regardless of the medium, ensuring consistent performance over prolonged usage periods.Minimal Pressure Loss: 4. Engineered with precision, the pressure loss remains between 0.08kPa and 0.58kPa across different specifications. The flowmeter boasts high integration and low power consumption, harnessing advanced microcomputer technology and top-tier integrated chips to deliver robust performance and exceptional capabilities.Compact and Efficient Design: 5. Integrating pressure, temperature, and flow sensors within a singular unit, the flowmeter's design is markedly compact. The inclusion of digital pressure and temperature sensors ensures seamless functionality. 6. The digital temperature and pressure sensors come equipped with independent calibration and verification features, simplifying replacement, maintenance, and operational processes. 7. Advanced Sectional Correction:Utilizing the flow frequency signal, the instrument's coefficient is segmented into nine distinct sections for automatic linear correction, significantly enhancing the instrument's accuracy across a broad range. 8. Comprehensive Data Storage Capacity:Equipped with an E2PROM data storage chip, this flowmeter preserves both user and manufacturer parameters. Its timely data-saving function safeguards against data loss during unexpected power outages, ensuring that internal parameters remain permanently intact even when power is lost. 9. Extensive Output Options:The intelligent flow meter is equipped with a comprehensive array of outputs, including base meter pulse output, working or standard condition pulse signal output, and calibration pulse output. Additionally, it can deliver a 4~20mA analog signal and RS485 communication to meet user-specific requirements, facilitating efficient data management and traceability. 10. Real-Time Database Access:Through an RS-485 communication interface, a real-time database is accessible for in-depth analysis and query. 11. The B-type meter in this series features a GPRS transmission capability, enabling seamless online, scheduled, and fixed-point data transmission. It allows for comprehensive monitoring of instrument data, valve control, pipeline pressure, gas alarms, and more, simplifying the construction of a GPRS wireless network system.PRINCIPLEThe Intelligent Gas Roots Flowmeter is meticulously constructed from a robust housing, conjugate rotor, and an advanced flow integrator. The conjugate rotors within the metering chamber are maintained in precise alignment through expertly machined calibration gears, driven by the pressure differential between the inlet and outlet (P_in > P_out). This design ensures optimal working clearances are preserved between all components, facilitating continuous, non-contact sealing. Each complete rotation of the rotor results in the output of four times the effective volume of gas from the metering chamber.TECHNICAL PARAMETERNominal diameter(mm)range ratioFlow range(m3/h)starting flow(m3/h)Pressure loss Pa at QmaxMaximum working pressure MPaNominal pressure MPamaterial2520:11-200.071100.41.6aluminum cast iron4040:11-400.061405030:12-600.071205040:12-800.071608035:13-1000.061708050:13-1500.051508050:14-2000.151800.40.610080:14-3000.1220010090:15-4500.1140015080:18-6500.6556015090:111-11000.8600Complete QualificationsFully QualifiedOur distinguished certifications underscore our commitment to excellence and reliability.
