Digital M-Bus Remote Reading Water Meter

Specifications

1. Dry Type Keep Clear Dial For Long Time; 2. Remote Reading save manager cost; 3. efficient Meter Reading

M-Bus is especially applied as the Bus structure of public utilities' meters, called as Meter-Bus, short for M-Bus. M-Bus meter bus line pertains to LAN (Local Area Network), is a special network for the same residential building, campus or a certain region within several kilometers that being applied in connecting long distance monitor computer and workstation and the measuring instruments etc.

Product Features:
1>Confirms to EN13757-2 2004 international standard, with a favorable compatibility and openness, meanwhile supports various meter types, such as water/electricity/gas/heat meters etc.
2>Adopt two wire connection mode, enables a long communication distance and bus power supply
3>Non-polar of the transmission line, willfully branch of the network topology, easy network, shooting the problem of meter breakdown and failure of meter reading caused by Bus line misconnection
4>Double power supply modes: Lithium battery and Bus line power supply
5>Real-time reading of the current meter data and monthly data within a year
6>Low power dissipation, quiescent operation current below 5 μ A, guarantee battery of a long service life

Product Advantages:
*M-Bus is the common international standard of consumer instruments, whose topology structure is the Bus line that applies the most common two wires connection and offers/fulfills the function of metering power supply & data communication.
*Non-polar of the Bus line in connecting, willfully wiring construction of the topology network, thus hugely cuts the construction cost & difficulty.
*Bus Line enjoys a perfect compatibility and openness.
*Strong compatibility/generality of its topology structure, allow liner/loop/star or various mixed types.
