KM06-05
Dry magnetic transmission structure ensures a clean and clear display of the counter.
 
            
           
 
          Description
1. Application
Measuring, memorizing and displaying the volume of cold(hot) water passing through the pipeline.
2. Feature
● Directly read word wheel data, basically achieving "zero" error copy.
● Low power consumption, power supply only when reading.
● Electronic unit completely sealed in the counter, no erosion from external water.
● Advanced data coding and verification, high communication reliability.
● Using bus mode, easy installation, less maintenance, cost saving.
● Meet EMC, ESD, EMI and other electronic products EMC design requirements.
● Use fault diagnosis and shutdown technology to ensure the whole network's safety.
● Networking with upper computer system, can remote automatic meter reading, and manual centralized meter reading.
