Tamper and Fraud Proof STS Prepaid Water Meter With a CIU in Home
RF Communication
The CA568 is a multi-jet dry dial type, cold water prepaid meter.
The meter is designed for metering application in grit particle
water meter environment. As multi-jet type, CA568 never gets
clogged or lose accuracy during its life time. Double strainers
protect the counter piece from damaged by small particles in water.
The ball valve inside is driven by a low energy motor and turns off
when water credits finish or tamper is detected, or battery is low.
The meter operates with latest STS prepayment standard and can be
topup with 20 digits' token codes. It supports all mainstream third
party payment platforms such as mobile money, EasyPay, Direct Pay
Online (DPO), credit card, etc. It offers fast money recovery and
24x7 non-watch vending.
CA568-S is offered with a handy remote keypad as "CIU", customer
interface unit. It is mounted within customers house and in radio
connection with the meter installed out side. Customer can input
recharge token and toggle info check on CIU with no touch with the
meter. This split mechanism vastly prevents tamper.
Water meter is being a great market in Africa, we have provided it
to Nigeria, Ethiopia, Kenya and so on
Calinmeter is so far the only manufacturer in China who has applied
STS technology not only electricity meter but also water meter. I
believe that Calinmeter can make your metering business better and
better
