CashWater STS Compliant Brass body Prepaid Water meter

The CA568 series CashWater is a multi-jet wet type, STS compliant prepaid water meter.  As a counterpart to Cashpower electric prepaid meter, CA568 works in the same principle, and it is equipped with a motor driven ball valve that shuts off water when the credit drains .
 
The meter works with a customer interface unit(CIU) through Radio communication.The CIU is installed indoor away from the meter. Consumers buy 20 digits' credit token from the point of sales and input it to the CIU to topup credit to the meter. 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.

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. 
 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.
