GSM/GPRS Wireless Transmission Data Logger (3G/4G)
Industry type:Electronics and communication
Product model number:GTI
award 3

The advanced multi-channel wireless datalogger, GTI model is the most powerful meter reading datalogger. Equipped with LCD display panel, GTI can let user verify the flow and pressure data on site. In addition, user can configure the parameters setting via IR technology and monitor flow, pressure and quality with the cloud-based application software. In the past, users all need to visit site and collect data which is time-consuming task, but with the development of GTI, users can monitor water data via mobile device, like smartphones or tablets (available in iOS / Android System). Moreover, in the era of IOT, GTI can connect various sensors and provide user real-time information. With the advancement of GTI model, we can monitor assets, deliver data and bring control seamlessly.

Founded in 1991, Energy Management System Company (EMS) is a dedicated smart water metering solutions provider based in Southern Taiwan Science Park, Taiwan. The smart water network solutions have been developed and installed for more than 90% of the water supply networks in Taiwan. From smart water meters (hardware) to the software (water supply monitoring platform), all have been designed and developed by EMS company in Taiwan.
Our innovative smart water management solutions have received various recognitions, such as “EU Smart Water Meter Applications” in 2011, “USA Pittsburgh INPEX Awards” in 2013, and “Taiwan Excellence” for 7 years.
From the past decade, due to climate changes, raining and typhoon seasons have occurred unexpectedly. We hope to bring the importance of the water awareness to the water utilities, industrial and commercial sectors. Implementing “TAIWAN WATER METER & SMART WATER MANAGEMENT” is our goal and promote Taiwan Water Technology on the world stage.


The founder of EMS, Mr. Ma Chuan, has attended AWWA annual meeting in 1989 and attracted by the advanced electronic water meter due to its accurate measurement and smart functions from the exhibition. At that time, water shortage is a big challenge in Taiwan. If we have Taiwan-made electronic water meter, Mr. Ma believe we can find out leakage effectively and reduce water loss.
In 1991, EMS has been created from a group of engineers. In 1993, the 1st Taiwan-made electronic water meter has been released on the market. People always said that the history of EMS company just like the historical development of the Taiwan electronic water meter.
EMS dedicated to developing smart water meter, IoT dataloggers and software systems as the total solutions for our customers from water utilities, industrial and commercial applications. Not only in Taiwan, but also from Vietnam, Thailand, Indonesia and South Africa, we have successfully installed our smart water metering solutions.
