Features
Product Introduction
The device has a 4G Cat-1 wireless transmission module, 2G+4G network and GNSS positioning, which can be modified to 2G+4G network according to the requirements and the frequency bands of different countries and regions around the world, thus allowing data to be acquired and transmitted remotely where the power supply to the device is not available.
The device uses a built-in high-capacity battery that eliminates the use of external power supply and does not require additional power to operate, ensuring that the device is able to be used to acquire and transmit data remotely.
Strong Compatibility
Accommodates several photoelectric ports in addition to accommodating different communication interfaces of on-site meters.
Available Range
All the Protocols of Water Meters, Electricity Meters, Gas Meters and Heat Meters are all supported to plug and play without extra development. DTU is able to attain Remote Control and Environmental Data Collection.
Multi-Mode All Network Connectivity
Different Countries Using Different Communication Cards states that the User has the freedom to select 2G/3G/4G and various data packets.
Communication Cards that Tespro Provides Can be Used all over the world.Multiple-Mode Full Network is supported, it is appropriate to work in the global communication network but just buy a new communication card and insert it then put it to work.
Supported Protocols and Methods
We are aware of the existence of numerous protocols, and corresponding equipment to various protocols could be irritating. But HHT works with any protocols.

Case
Product Case
22 October 2024 - LONDON - A significant British utility has ordered 320 TD-DTU systems through our direct supply to modernise its metering systems.
The equipment will facilitate the implementation of nationwide smart meter in England, Scotland and Wales, gathering information on residential/commercial electricity, water and gas meters and following the UK Smart Metering Specification.
The primary capabilities of the TD-DTUs: the integrated data storage eliminates the use of laptops by field personnel, and high-speed transmission transmits data to the cloud without any problems-reduced equipment load and delays.
The units have transformed the way things used to be done: manual and error prone logging and cumbersome gears are a thing of the past. Online gathering increases the precision, putting the verified data into the billing/analytics and hours of administration.
The team of the client refers to the TD-DTU rollout as the largest efficiency change they have had in 10 years, whereby no further revisions to the same sites and illegible field notes.
The devices will facilitate the national deployment of smart meters all in England, Scotland and Wales and will gather data on domestic/corporate electricity, water and gas meters and will adhere to the UK Smart Metering Specification.
