Wireless Remote Valve Control Water Meter

Wireless remote reading water meter is for measuring volume of cold (hot) water which passing through pipeline

Application:

Wireless remote transmission water meter and the AMR(automatic meter reading) system were designed for the Water Supply Department ,Which is new accounting management system. The system consists of 4 lever components: water meter, zone collector, GPRS concentrator and master point(management center). It adopt Zig-Bee with GPRS communication way to achieve a automatic and intelligent charge management.

 

FEATURE:

1. low-consumption design. only consume when meter need read.

2. valve control remote switch, No need battery.

3. combining with meter-reading system to realization the automatic meter reading.

MAIN TECHNICAL DATA: Water meter temperature grade: T30,T50,T70,T90

                                          Pressure grade:MAP10

                                          Pressure loss grade: P63

                                          Upstream disturbance grade:U5

                                          Downstream disturbance grade:D0

MAXIMUM PERMISSIBLE ERROR:

a) In the lower zone from Q1 inclusive up to but excluding Q2 is ±5%  

b) If the temperature≤30°C, In the upper zone from Q2 inclusive up to and including Q4 is ±2%

c) If the temperature>30°C, In the upper zone from Q2 inclusive up to and including Q4 is ±3%
