1.项目概述  Project Overview

中国香港某项目需要一批物联网电力仪表且具备远程抄表功能更换原先的指针表，经推荐我司APM810多功能仪表和AWT100/4GH网关以及物联网平台。中国香港客户多方面对比后，认可我们的仪表安装方便，功能强大，且结合我们的网关(AWT系列)，具备远程抄表功能，客户通过手机APP或网页登录即可随时随地监控用电情况。

A project in Hong Kong requires a batch of Internet of Things power meters with remotely reading function to replace the original pointer meter. We have recommended our APM810 multi-function power meter, AWT100/4GHW gateway and IoT Cloud Platform.After comparing in various aspects, Hong Kong customer recognize that our power meter is convenient to install with rich functions.Using with our gateway(AWT series), it could connect with our IoT Cloud Platform and check the data remotely. Customers can monitor the electricity situation anytime and anywhere through mobile phone APP or web login.
