GE AT868-2-1-1 Ultrasonic Flow Transmitter AquaTrans AT868 Dual Channel Industrial Flow Meter

Product Overview

The GE AT868-2-1-1 is a dual-channel ultrasonic flow transmitter designed for accurate and reliable liquid flow measurement in industrial and municipal environments. As part of the AquaTrans AT868 series, this instrument is built to deliver stable long-term performance using advanced transit-time ultrasonic technology. It is widely used in water treatment systems, distribution networks, and industrial process control applications where precise flow monitoring is required.

Measurement Principle

This flow transmitter operates using the transit-time ultrasonic measurement principle. Ultrasonic signals are transmitted both upstream and downstream through the fluid. The difference in travel time between these signals is used to calculate the flow velocity. This method ensures high accuracy and stability, especially in clean or lightly contaminated liquids such as water and water-based solutions.

Dual Channel Configuration

The AT868-2-1-1 features a dual-channel architecture, allowing simultaneous measurement of two separate flow paths or the averaging of two signal paths within a single pipeline. This improves measurement reliability and reduces uncertainty in demanding industrial environments. Dual-channel processing also enhances diagnostic capabilities and system redundancy.

System Integration and Output

The device is designed for flexible integration into industrial control systems. It supports multiple output options including analog current signals and pulse outputs for flow totalization. Communication capabilities allow it to interface with monitoring systems and automation platforms, making it suitable for modern SCADA and process control environments.

Performance and Reliability

The GE AT868-2-1-1 is engineered for continuous operation in industrial environments. Its ultrasonic measurement technology eliminates the need for moving mechanical parts, reducing wear and long-term maintenance requirements. The system maintains stable performance even under varying flow conditions, ensuring consistent measurement accuracy over time.

Applications

This ultrasonic flow transmitter is commonly used in water-related industrial processes, including municipal water supply systems, wastewater treatment plants, cooling water circulation systems, and general process water monitoring. It is suitable for environments requiring non-intrusive and reliable flow measurement technology.

Installation Flexibility

The system supports flexible installation configurations depending on pipeline conditions and application requirements. It can be adapted to different pipe sizes and materials, making it a versatile solution for both retrofit and new installations. Proper installation ensures optimal signal transmission and measurement accuracy.

Operational Advantages

One of the key advantages of the AT868 series is its non-intrusive measurement method, which allows flow monitoring without disrupting the pipeline. This reduces downtime during installation and maintenance. Additionally, the absence of moving parts contributes to long service life and consistent performance in demanding environments.

Industrial Use Cases

In industrial water management systems, the GE AT868-2-1-1 provides accurate flow data that supports process optimization, energy efficiency, and resource management. It is particularly valuable in systems where precise flow measurement is required for operational control and reporting.

Conclusion

The GE AT868-2-1-1 ultrasonic flow transmitter is a reliable and efficient solution for modern flow measurement applications. With its dual-channel design, transit-time measurement technology, and flexible integration capabilities, it is well suited for a wide range of industrial and municipal water flow monitoring systems.
