The ultrasonic metering instrument has achieved "domestic production," featuring a fully independently developed "ultrasonic metering module." This breakthrough has resulted in multiple patents across key areas such as flow channel design, transducer packaging, the core circuit board, and embedded software algorithms—placing the technology at an advanced level both domestically and internationally in this field.
Commercial Ultrasonic Gas Meter
The industrial ultrasonic gas meter is a fully intelligent measuring device that employs highly sensitive ultrasonic sensors. It uses the time-difference method to measure gas flow velocity, converting the time difference into a velocity reading. This value is then processed by an onboard microcontroller to calculate the actual gas flow rate, which is ultimately displayed. The meter is ideally suited for accurately measuring the flow of various types of natural gas.
Ultrasonic Gas Metering Module
The Hangyu Xing Ultrasonic Gas Metering Module is a newly developed, fully in-house-designed electronic metering module that boasts numerous advantages, including its compact size, simple yet robust design, high measurement accuracy, wide flow range, and ultra-low power consumption. It also features advanced functionalities such as wireless NB-IoT communication, real-time temperature and pressure compensation, reverse-flow detection, and gas quality monitoring. This product complies with both the GB/T 39841-2021 standard for "Ultrasonic Gas Meters" and the JB/T 12958-2016 standard for "Household Ultrasonic Gas Meters."
Far-Transmitting Diaphragm Gas Meter (NB-IoT)
The FarEasTone Membrane Gas Meter (NB-IoT) is built on a dedicated IoT network provided by a telecommunications operator and consists of a base meter, an intelligent control unit, and an NB-IoT communication module. This smart IoT membrane gas meter periodically transmits metering data, operational status, and other relevant information to a monitoring platform via the operator’s NB-IoT network. The platform’s data center then analyzes this information to perform tasks such as billing, settlement, real-time monitoring of meter status, and issuing commands directly to the meter—enabling features like intelligent metering, remote meter surveillance, online payment, and automated anomaly alerts.
By installing an "intelligent module," we’ve enhanced both software and hardware with advanced safety control features, enabling real-time monitoring of issues such as gas flow overload, abnormal flow rates, excessively low gas pressure, and prolonged constant-current operation timeouts—effectively creating a robust protective barrier to safeguard users’ lives and property.
Smart Electronic Gas Meter with Temperature and Pressure Compensation
By applying temperature and pressure corrections to compensate for errors in gas metering, the accuracy of gas measurements is improved, creating a truly fair, transparent, and equitable trading platform for both users and gas suppliers.
The IC card-based membrane gas meter features prepaid functionality and tiered pricing, with the option to add a gas-leak detection and automatic valve-shutoff feature. Users can set multiple billing thresholds and customize various tiered rates, allowing the meter to automatically calculate the appropriate discount based on the month’s actual consumption. This next-generation smart gas flow meter utilizes an IC card for prepaid payment and incorporates advanced automatic billing capabilities. It is compatible with a wide range of combustible gases, including natural gas, liquefied petroleum gas (LPG), and city gas, making it the ideal metering device for modernizing gas management systems. Inside the meter, a low-power 16-bit MCU ensures seamless operation, handling all program functions and data processing automatically. Gas distribution authorities can remotely manage user accounts via computer—enabling features like pre-selling gas credits, setting secure IC card passwords, and retrieving real-time data on remaining gas levels and cumulative usage. Additionally, dedicated management software allows operators to create comprehensive user profiles, storing essential customer information for efficient record-keeping.
Commercial and Industrial Diaphragm Gas Meters
Suitable for measuring large-diameter pipelines carrying coal gas, liquefied petroleum gas, natural gas, biogas, air, and other non-corrosive gases, this meter boasts high sensitivity, accurate and reliable measurement. It also features advanced functionalities such as prepaid gas billing, tiered pricing, and wireless communication, making it an intelligent metering device perfectly tailored for modern gas management systems. The industrial gas meter utilizes a microcomputer to automatically measure and store gas consumption data, while continuously monitoring the meter's operational status, battery level, and other critical parameters. In case of anomalies, the system triggers automatic alerts and uploads the information in real time. Additionally, through an application server, users can remotely manage pricing adjustments, implement tiered pricing models with multiple rate structures, and oversee various administrative tasks—including instrument status tracking and valve control—ensuring seamless and efficient operation.
Steel-cased diaphragm gas meter
The independent metering movement design primarily consists of a diaphragm, a diaphragm housing, a unidirectional rotary valve distribution system, and a transmission mechanism. The steel casing has undergone a rigorous 500-hour salt-spray corrosion resistance test, ensuring it forms an airtight and fire-resistant protective enclosure. The metering movement’s diaphragm housing is precision-molded from corrosion-resistant engineering plastic. Advanced manufacturing techniques such as ultrasonic bonding and friction welding are employed to securely integrate components like the diaphragm cover bracket into a highly airtight assembly, significantly enhancing both reliability and long-term stability. The synthetic diaphragm is crafted by coating polyester fibers on both sides with adhesive, followed by vulcanization—a process that delivers exceptional flexural performance, enduring up to 3 million cycles without puncture. Additionally, the unit can withstand a total ventilation capacity of up to 4,500 m³ during extended lifespan testing. Meanwhile, the valve seat and valve cover are manufactured using phenolic thermoset plastic molded under high pressure, offering superior wear resistance, minimal water absorption, and consistently low friction coefficients over time. Finally, the transmission system features a unidirectional rotary distribution valve, which simplifies the mechanical structure while boosting overall reliability. To further ensure accuracy, the movement incorporates an anti-reverse device that prevents the counter from reversing unexpectedly.
Aluminum-Shell Diaphragm Gas Meter
The Hangyu Xing aluminum-cased series of base meters is designed for measuring gases such as liquefied petroleum gas, natural gas, city gas, and chemical gases. This product boasts several key features: compact size, elegant aesthetics, high sensitivity, exceptional accuracy in measurement, excellent stability, robust reliability, superior resistance to high pressure and corrosion, and an extended service life—all coupled with convenient maintenance. The upper housing and main body of the mechanical aluminum gas meter are both precision-molded from high-quality aluminum alloy, ensuring durability and performance. The exterior and interior surfaces of the housing undergo advanced anti-corrosion treatment using pure polyester powder coatings specifically formulated for outdoor applications, fully compliant with the stringent European RoHS environmental standards. Equipped with a 360-degree rotating valve mechanism, this meter minimizes friction while maintaining strong resistance against gas impurities and contaminants—a hallmark of its exceptional sensitivity. Additionally, cutting-edge visual processing technology ensures clear, easy-to-read meter readings at a glance. With a wide measurement range, the meter accurately captures flow rates spanning from a minimal 0.016 m³/h up to a maximum of 6 m³/h. The valve seat and cover are crafted from advanced synthetic resins like phenolic compounds, offering enhanced wear resistance and improved long-term stability. Imported from Europe, the diaphragm material exhibits outstanding quality, passing rigorous flexural testing over 3 million cycles.
