Project Description
STS IP68 Plastic Smart Prepayment Water Meter
ISW1598 STS Split Plastic Smart Prepayment Water Meter consists of basic plastic water meter and remote customer interface unit(CIU). Firstly, the basic plastic water meter includes an electronic PCBA part for measurement, valve controlling, battery & LCD dispayer. Additionally, the communication between water meter and CIU is Lora module. What’s more, it has advantages of low power consumption, high reliability, high accuracy, multi-function, automatic valve maintenance and easily installment & use.
Function&Feature
| Comply with Directive 2014/32/EU, OMIL R-49:2013(E)& EN14154. |
| Wet dial or dry dial register for water meter is selectable. |
| Prepayment and post-paid mode is switchable. |
| Low credit warning is programmable. |
| Charging water amount by 20-digit TOKEN from POS point or direct charging from vending system. |
| Anti-return valve to be against reverse-flow. |
| RF Lora communication: Wireless communication operation frequency band is 433MHz, which will be adjustable as per client’s requirement. |
| CIU supports to match freely with different water meters |
| Low battery detection: water meter will detect battery capacity when valve opens or closes. |
