| Measurement accuracy | Level 1.0 |
| Repeatability | 0.2%. |
| Flow rate range | Below DN200 (inclusive) 0.3- 4m/S; above DN200 0.3-6m/s |
| Measurement principle | Principle of ultrasonic propagation time difference, dual CPUs working in parallel, 4-byte floating point operation |
| Measurement period | 500mS (2 times per second) |
| Working power supply | Isolated DC8-36V or AC85-264V |
| Signal input | 3 channels of 4-20mA analog input, which can input pressure, liquid level, temperature and other signals; 2 channels of three-wire platinum resistors |
| Signal output | 1 isolated RS485 output; 1 isolated 4 20mA or 0 20mA output (active or passive optional) |
| Optional HART protocol; dual isolated OCT outputs | |
| 1 bidirectional serial interface, universal interface for peripherals, connects 4-20mA, frequency signals, thermal printers, data loggers, etc. | |
| Protocol | Modbus RTU protocol |
| Power consumption | Working current 50mA (when the keyboard is not connected and the buzzer does not sound) |

| Other functions | Automatically memorizes the previous 512 days, the previous 128 months, and the previous 10 years. The positive and negative net accumulated flow rates can be automatically remembered for the previous 30 times. The power-on and power-off times and flow rates can be automatically or manually added, and can be read out through the Modbus protocol. |
| Sensor | External application, insertion and tube type |
