The CA568-A series is our newest design with R160 accuracy and IP68 protection. High they can be used in a very harsh and humid environment, even work well under the water. The high level accuracy bring better metrology. Up to 10 years battery life, data storge all the meter's lifetime.
The CA568-A have the reading remotely based on RF- Lora communication and CALIN's AMR/AMI management software. 1 DCU( data concentrator) can collect the data from 600 meters in 1KM range. At the same time, the CIU (Customer Interface Unit) connect the wate rmeter though RF-Lora communication, will working well in 300 m range, the user can stay the house to realize recharging and checking the information for the meter.
