1.Product Overview
The intelligent gas Roots flowmeter is a positive displacement metering instrument that measures gas volume by counting the revolutions of a pair of figure-eight Roots rotors within the metering chamber. It features high measurement accuracy and excellent stability, making it suitable for trade measurement of medium-to-high pressure gases such as natural gas, coal gas, and propane. It is widely applied in high-precision metering scenarios across urban gas transmission and distribution, petrochemical industries, and other fields.
2.Product Advantages
Exceptionally high measurement accuracy (±1% R) with outstanding repeatability (≤ 0.2%), meeting trade measurement requirements;
Wide turndown ratio with exceptional low-flow measurement performance;
Built-in high-precision temperature and pressure sensors support online compensation for standard-condition volume/energy measurement;
High-precision synchronous gear-driven rotor with non-contact operation, minimal wear, and extended service life;
Features data power-off protection and self-diagnostic fault detection;
IP67 protection rating for harsh outdoor environments;
Supports pulse signal and 4-20mA analog signal outputs, compatible with Modbus communication protocol for smart pipeline network integration.
Dual power supply design with 3.6V lithium battery and DC 12–24V, offering up to 5 years of battery life;
Features low-voltage alarm and data loss protection, permanently storing up to 12 months of historical data;
Integrated self-diagnostic function automatically identifies temperature/pressure sensor failures with real-time alerts;
When paired with dedicated management software, generates data reports and trend curves to support flow data analysis and energy consumption control;
Features real-time data storage, recording start/stop events and daily data while enabling historical data queries.
Optional GSM wireless transmission module available; when paired with dedicated management software, generates data reports and trend curves to support flow data analysis and energy consumption control.
