Ⅰ. Product Features
Combines flow measurement, CPU card operation, volume adjustment, and control into a compact structure with high reliability, accurate calculation, and quick and timely control.
Flow compensation controller features an external digital temperature and pressure sensor, high accuracy, and easy maintenance and calibration.
■Mature计量Base Tables: Utilizing our company's manufactured and market-proven计量Base Tables with stable performance, reliable operation, and accurate measurement.
■ Reliable control ball valve: zero pressure loss structural design, valve passage diameter equal to pipe diameter, reliable operation of valve opening and closing.
■ Utilizing a primary and auxiliary battery power supply, featuring a low-power consumption circuit design. The built-in battery can last for over three years, and an external power source can be connected for long-term supply. It ensures reliable opening and closing of the valve.
■LCD displays total cumulative, instantaneous flow rate, temperature, pressure, remaining gas volume, battery status, valve status, etc., with clear and intuitive display, easy to read numbers;
■Utilizes EEPROM data storage technology, featuring historical data storage and query functions;
■ Utilizes CPU card and embeds an ESAM security module; every operation on the card requires security authentication, ensuring high security.
■ The card can store the reading information of each meter, allowing the gas company to read all the information within the card through the user management system during gas sales, facilitating user management.
■ Features pulse signal output and RS485 communication interface, convenient for connecting to a host computer, and can be paired with data collectors to achieve wireless data collection.
II. Features
Pre-paid management through IC cards, one meter with one card, featuring different user passwords for enhanced security and reliability.
2. LCD display of gas volume information and valve control, along with low volume, fault, low power, and other related information and status.
3. Powered by a high-capacity lithium battery, extending the service life; the battery life is typically over 3 years under normal use.
4. The controller features battery power detection. When the battery power is low, the system will automatically display "Low Power" and sound an alarm, and the valve will shut off automatically within the preset time.
5. The controller features multiple protective functions. In the event of opening the box, wire breakage, power failure, or magnetic dryness, the controller will automatically close the valve and shut off the gas supply. Simultaneously, the LCD will display prompts such as "Fault" and "Close Valve."
6. Press to view remaining gas volume, cumulative gas usage, and status information.
7. The controller features an external power detection function. When the flowmeter's base battery or external power is low, the controller will automatically close the valve and display the corresponding fault information.
8. The controller features flow signal monitoring capabilities. If the controller does not receive the flow meter's signal within the set time, it will close the valve and display the corresponding fault information.
9. Press to view remaining gas volume, cumulative gas usage, and status information.
10. Compatible with 485 communication interface for flow meters, real-time verification of cumulative data.
11. Features a large LCD screen to display gas volume and status information, clear and intuitive.
12. The controller header can rotate 180 degrees for easy installation and use.

VII. Cautionary Notes
After removing the IC card, the card slot must be sealed to prevent dirt from entering.
2. This product operates on a one-account-one-meter-one-card system. The IC card must be kept safely, not damaged, and cannot be borrowed among individuals.
3. When replacing the external battery, ensure there are no flammable gases present at the installation site before proceeding; for internal battery replacement, please contact the local gas company.
4. To ensure normal operation of the IC card gas products, please use 5号alkaline batteries, and strictly prohibit the use of AC power to replace battery power.
5. Do not place magnetic materials near IC gas products; otherwise, you may not be able to use them.
6. When connecting to the flow meter, install it in the direction indicated by the controller arrow, aligning with the arrow on the flow meter, and do not reverse it to avoid inconvenience.
