Brass Ball Valve Potable Water Flow Meter 4 Channels For Cold Water Dry Dial

AMR water meter with control valve, dry dial for cold potable water flow metering DN15-DN25

Work principle

This multi jet water meter, is with built in control ball valve, through automatic meter reading system consists of M-BUS water meter, collector, concentrator and management software.

1. Basic communication device: M-BUS collector and measurement meter transmit data by M-BUS line with 4 channels, and can connect the meter according to any topological structure. Build in backup battery, could works for 48 hours normally, and the data can be saved for 10 years if power is cut off.

2. Relay communication: Middle layer communication means the communication between the concentrator and collector. This communication is by wireless RF way, no need of communication line. The wireless communication distance between the concentrator and collector can be about 3km at open environment.

3. Upper transfer communication: Communication methods indicate below can be selected between concentrator and management center.

(a) GPRS Communication Mode

(b)Telephone Line Communication Mode

(c) RS232 Communication Mode

(d) Ethernet Communication Mode

FUNCTIONS

1. Monitor all the meters in a control center remotely, no need to read meter house by house.

2. Automatically meter-reading of all the meters or any one of them, including original data, present used amount or historical data.

3. Automatically valve control of any meter.

4. Automatically monitor unexpected illegal use, like disconnection, short circuit, being attacked or meter remove.

5. Smart software guarantees data storage, meter-reading, reports print and alarming for power deficiency.

Features

1.Totally sealed design, waterproof.

2. Automatically memorize the wheel code position and no need initiation.

3. Avoiding external strong magnetic attack, high performance of anti-interference.

4. Effectively solve the phenomenon of reversing and hammering.

5. Adopting M-BUS communication port, which with long distance communication.

6. No need power supply for daily work.

7. With remote valve control function that can stop water supply remotely.
