Photoelectric direct reading remote water meter

• Accurately meter reading
  
• Directly reading the "window value" of the meter by using advanced photoelectric technology, it just transfer the numbers shown on digit rollers to digit data as you see it by your eyes ,not like pulse output which adopts cumulative pulse ,so there is no cumulative error
• The electronic part of the direct reading water meter not contacted with the counter in the water meter, and is not affected by the jitter;
• The meter adopts infrared photoelectric direct reading mode, which is not affected by electromagnetic interference and light interference.
• Special circuit processing method, which reliably solves the carry-over problem of common direct-flow water meters (such as 200, 399, 209, 290, 390, 309 when carrying between 299 and 300) and water metering The reliability of meter reading data.
  
  
• Stable long term function
• Using Mbus wire,no wireless signal problems
  
  
• Convenient to read the AMR water meters
  
• No need to set the parameters, no need to store data
  
  

• Low power consumption "energy saving"
• The electronic device only be powered by the concentrator and through Mbus wire once the instantaneous reading is needed,so the power consumption is greatly reduced.
  
  
• Lightning protection and other safety features
• the direct reading water meter equiped with the lightning protection circuit and the reliability is further enhanced.
  
  
• Long service life
• Since electronic parts does not need long-term work,so most of time ,it’s just in state of silent watting. which avoids various kinds of interference damage (such as lightning, static electricity, etc.)
• during the operation hereby greatly prolonging the service life of the meter reading system.
• Installation is simple and convenient, less maintenance, low cost Adopt M-BUS bus mode, no polarity, so wiring is simple and convenient;
• direct reading meter reading system has no reading error, system does not need long-term power supply, no backup battery is needed so maintenance is low and costs are low.

• Nominal diameter: DN15,DN20,DN25,DN40
• Working water pressure: 0.03MPa-1.0 MPa
• Pressure loss: ≤0.1Mpar Pressure: 1.6MPar
• Measurement Class:B
• Temperature: 0.1 ° C - 30 ° C

1. connect the Mbus wires to the meters on the one end ,and Mbus master station on the other end
2. connect Mbus master station to data concentrator which collecting the water consumption date in bundle ,then the concentrator wirelessly transmit the data to cloud server.the user’s platform/software obtains the data from the water meters Other instructions: The water meter and the M-BUS master station are connected by twisted pair shielded wires. The M-BUS interface of each M-BUS master station can be connected to 50-100 water meters
   The maximum distance between the data collector and the M-BUS master station is up to 1.2KM, and the distance between the M-BUS master station and the water meter is up to 1KM. The reading command triggered by the software management system, the M-BUS master station transmits the command to the direct reading water meter connected , each water meter has a unique identity (the AMR Water meter can be distinguished by the id number), the electronic parts reads the number of the digit rollers optically and encoded to the readable digits ,feedback the data to server and platform .
   

Network building options

• This system is a set of modern, automated and scientific management system. It has fast processing speed, high safety performance, large storage capacity, high efficiency and stability, and convenient management Features.
• Since a large amount of data information is stored in the microcomputer, it facilitates the retrieval, aggregation, and transmission of data, thereby liberating relevant managers from heavy labor and providing a basis for scientific decision-making of management.
