The Flow Error Curve:

a. In the lower zone (Q 1 ≤Q≤Q2): maximum permission error is ±5%
b. In the upper zone (Q2 ≤Q≤Q4): maximum permission error is ±2%( T≤30˚C), maximum permission error is ±3% (30˚C <T≤50˚C)
The Pressure Loss Curve:


We use NB-IOT module for the remote wirless transmission. NB-IoT refers to Narrow Band-Internet of Things technology.Focusing on the Low Power Wide Coverage (LPWA)Internet of Things (loT)market,NBIOT is an emerging technology that can be
widely used around the world. NB-IOT uses the license frequency band,and can be deployed in three ways: in-band,guard band,
or independent carrier to coexist with the existing network.
