Features

1. Built-in pressure, temperature and flow sensors with high safety, compact structure and exquisite shape.

2. Local indication of temperature, pressure, instantaneous flow and accumulative flow.

3. Use new signal processing amplifier and unique filtration technology, effectively eliminate interfering signal generated by pressure fluctuation and pipeline vibration, greatly improve anti-interference ability of flowmeter, and make good stability of little flow.

4. Special time indication and real-time data storage function; under no circumstance will the internal data be missing and will be stored forever.

5. Password protection

6. Low power consumption, internal battery supply, no need for external power supply.
