The CAW-15/20/25-C series is an STS (Standard Transfer Specification) compliant, electronic valve controlled, water meter. With CAW-C series you are assured of continuously good metrology and revenue protection at the same time.The electronic part of the meter is sealed away from the water, which makes the meter high reliable.
The meter uses a Smart RFID token Card to handle credit and monitor water use. Customers purchase credit at vending points, providing an opportunity to download new tariff data. Simultaneously, data from the meter, stored on the Smart Card, is uploaded and sent to the utility headquarters. Credit is top-up to the meter by a simple tap on the counter lid.
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.
