Main technical parameters

Shape dimension & figure

1．Battery life: Power consumption < 2.7 Ah / yr, 1 battery can be used continuously for more than 6 years.

2．Accurate metering : The pipe is designed for fluid stratified dual-channel measurement.

3．The Wide measure range, initiating flow is less than 0.01 m / s.

4．Lowest pressure loss.

Functions:

1．Digital display: 9 bits cumulative double lines display, 4 bit instantaneous flow display, as well as status prompt and unit.

2．Power supply: Built-in lithium battery (3.6V, 19Ah) / External 5V DC /4-20mA 2-wire power supply

3．Measuring period: 1 t/s (or 2~4times/s); calibrated state: 4 times / s.

4．GPRS remote transmission function.

5．Communication interface: RS485 / USARTIR
