This ultrasonic flow meter utilizes dedicated TI chips and clog-resistant sensors, delivering Class 1 accuracy, ultra-low start flow, and over 9-year battery life. With multi-protocol communication and horizontal/vertical installation, it is suitable for complex industrial environments.
1. Employs an ultrasonic flow sensor, preventing clogging and interference from metallic impurities, resulting in low resistance to the pipeline system and high metering accuracy.
2. Utilizes a dedicated control chip from Texas Instruments (TI) MSP430 series and a time control chip from Acam (Acam), offering a wide measurement range, large range ratio, low starting flow rate, high sensitivity, and more accurate metering.
3. Uses a high-performance lithium-ion battery and ultra-low power consumption design, with a working life of over 9 years.
4. Non-volatile memory stores data, ensuring data integrity even during power outages. Metering function automatically resumes upon power restoration, and it can store historical data for the past 24 months.
5. Isolated RS485 connection. The interface supports multiple commonly used communication protocols simultaneously, including MODBUS and M-BUS extended protocols, enabling remote data transmission and centralized control.
6. The LCD screen can cycle through various parameters such as flow rate, working time, fluid temperature, date, instantaneous flow rate, meter number, and voltage, providing a clear and intuitive display.
7. Adopting an integrated structural design, it is compact and space-saving; it can be installed horizontally or vertically, suitable for harsh working environments such as confined pipe shafts.
