- User-Friendly Interface: Supports Chinese and English menu displays for ease of operation.
- High Reliability: Utilizes low voltage, multi-pulse technology to enhance accuracy, lifespan, and overall reliability.
- Strong Anti-interference: Features a dual-balance signal differential receiver/driver circuit to minimize interference from external sources like converters, TV towers, and high voltage lines.
- Powerful Recording Function: Automatically records:
- Totalizer data for the last 512 days, 128 months, and 10 years.
- Time and corresponding flow meter data for the last 64 power on/off events.
- Working status for the last 32 days.

4. Setup and Installation
Proper installation is crucial for accurate measurements. Follow these general steps:
- Select Installation Location: Choose a straight section of pipe, free from bends, valves, or pumps that could cause turbulence. Ensure sufficient upstream and downstream straight pipe lengths as recommended in the full installation guide (refer to product documentation for specific requirements).
- Prepare the Pipe Surface: Clean the outer surface of the pipe where the transducers will be mounted. Remove any paint, rust, or debris to ensure good contact.
- Apply Coupling Agent: Apply a generous amount of ultrasonic coupling agent to the contact surfaces of both the transducers and the pipe. This agent is critical for transmitting ultrasonic signals.
- Mount Transducers: Attach the TS-2 transducers to the pipe using the provided clamp fixture. Ensure they are positioned correctly according to the flow direction and the specified distance for your pipe diameter. The transducers should be firmly secured to prevent movement.
- Connect Cables: Connect the transducer cables to the appropriate ports on the main transmitter unit. Ensure all connections are secure.
- Power On: Connect the DC8-36V power supply to the transmitter unit. The unit should power on and display the initial screen.
- Initial Configuration: Access the menu to input pipe parameters (material, outer diameter, wall thickness) and liquid parameters (type of liquid). These settings are vital for accurate flow calculation.
Note: For detailed installation diagrams and specific transducer spacing, please consult the comprehensive technical manual provided with your device.
5. Operating Instructions
