LCD Display Wireless Water Meter , Battery Driven Water Prepaid Meters split CIU RF communication

LCD Display Wireless Water Meter , Battery Driven Water Prepaid Meters split CIU RF communication 

The CAW-RL  is a multi-jet wet type, STS compliant prepaid water meter.  The meter works with a low power  bistable latched valve driven by battery that is able to open and shut for 4 million times during battery lifetime.  CAW-RL series assure you of continuously good metrology and revenue protection at the same time.The electronic part of the meter is potted and sealed above on the metering chamber, away from the water, which makes the meter water proof and adaptable to humid and tropical environments.

The meter works with a customer interface unit(CIU) through Radio wireless communication. The CIU is installed within customer’s premise when the meter is installed in a meter cabinet or kiosk on pavement away from the customer. The STS decryption takes place with the meter and the CIU provides a convenient interface to the customer. Information like token acceptance and rejection, credit status, historical usage data can be displayed with the LCD of the CIU.This split design makes the meter immune to any tamper and fraud on CIU side.The meter is reinforced in its wireless communication with LoRa technology, allowing the meter to communicate with a Customer Interface Unit (CIU) or a head-end Server (HES) from a visual distance up to 1 mile. This split type makes the water meter immune to whatever tamper or fraud with the CIUs.

To top-up or recharge the water meter, a consumer just need to purchase 20 digits'  credit token from the vendor and punch in the code with the CIU. With our broad range of prepaid vending solutions, a utility or service provider can manage CAW series water meter along with STS prepaid electricity meters in one vending system.
