Smart Dn15 Water Meter Wired Mbus 16 Bar Fully Sealed Register Clear Reading

DN15 wired mbus smart water meter, fully sealed register clear reading

General introduction

This new smart water meter, is one type of AMR water meter. Communicaiton is through wired Mbus, CJ188 protocol, easily for remote reading. The base water meter is multi jet impeller type water meter, fully sealed register. The type of water meter can work in the environment of high humidity, but no fog inside the register, so it can keep clearly reading.

Work logic

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

Applications:

Industrial and commercial water supply, volumetric water flow metering and automatic meter reading for utility, irrigation.

FUNCTIONS

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.

Product data sheet

Installation

• The installation of water meter meets the installation requirements of ISO4064-2:2005
• The caliber of water meter shall correspond with caliber of pipes and the used flow rate is less than or close to the permanent flowrate. The installation place should avoid exposure, flooding, freeze and pollution, and convenient for installing, removing and reading data.
• The water meter shall be installed horizontally (display surface is upward).
• The sands and stones and other sundries in the pipelines shall be cleared.
• The arrow on the water meter should be the same as the water flow in the pipeline.
• If the water meter is installed on the inlet of the boiler, it is better to install inverted valve on the outlet of water to prevent the return current of hot water and steam will damage the water meter.

Competitive Advantage:

• Compliance to international standards: ISO4064 / GBT778 / Q/320700JR05-2003
• Strict process control
• Advanced calibration equipment
• Engineer team
