Wired Remote Reading Water Meter

Wired remote reading water meter is for measuring, memorizing and displaying volume of cold (hot) water passing through pipeline

This series of water meter is used for family or a resident's measuring the gross volume of water flow which passed through pipeline. It has strong anti-jamming and high reliability, energy saving and have long lifetime. The system consists of water meter, zone collector, concentrator and terminal processor (administration center).

It adopt RS-485 or MBUS with GPRS communication way to achieve automatic and intelligent calculation and charging management.

Feature:

1. Accurate reading .

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

3. It’s not the pulse accumulation type measurement, don’t need initialization .

4. Mechanical reading and electronic reading will keep exactly the same

5. Numeral transmission.It can keep the measurement stable, accurate and reliable in complex environment.

6.The sensor is non-magnetic and non-contact ,This ensures the reading keep in high precision.
