Product Description
Company Profile
Topscomm Communication was founded in 2008 and listed on the Shanghai Stock Exchange in October 2016 (stock code 603421). The company has a 220000 square meter automated production base, a 37000 square meter research and development center, and a 22000 square meter CNAS accredited laboratory. It is a group enterprise based on independent research and development platforms,independent IC design, independent embedded software, independent engineering design, and independent automated production.
The company relies on two original technologies in power electronics and signal processing to build three basic platforms: independent original chips, a full value chain intelligent manufacturing platform, and a CNAS certified full process quality control system. These platforms support five business segments: AMI, IDS smart distribution network, IES smart new energy, smart streetlights, and smart water management. They provide efficient, intelligent, and sustainable full range solutions, providing high-quality technology supply for "carbon peak and carbon neutrality". The company adheres to the concept of "ecological cooperation and open innovation", actively seeks partners, introduces external innovation resources, builds a business ecosystem, achieves mutual benefit and win-win results, and jointly promotes new technological innovation and industrial upgrading.
Our Advantages

FAQ
1：What are the advantages of Dingxin water meter for leak control？ |
From the perspective of measurement, using high-precision water meters can reduce measurement leakage. The range ratio of Dingxin water meter can reach up to R800, and the starting flow rate can reach as low as 1L/h, with a wider measurement range. Mechanical meters have high starting flow rates, and compared to mechanical meters, we can accurately measure small flow rates that cannot be measured by mechanical meters. Although the reduction in leakage water from each terminal is not significant, the number of terminal measurements is too large, resulting in a large total. |
2：Is there a rotation issue? Will there be a measurement if there is no water in the pipeline, just air flow? |
This problem often occurs in mechanical water meters, and ultrasonic water meters do not have this situation. From the principle of ultrasonic measurement, the propagation speed of sound waves in water (about 1500m/s) is approximately 4.4 times that in air (about 340m/s). Ultrasonic water meters can detect the presence of water in pipelines through the transmission time of sound waves. If there is no water, no measurement will be generated and an "air traffic control" alarm will be reported. |
3：What is the frequency of measurement? |
It is measured once per second, that is, the frequency is 1Hz, and the measurement error can meet the requirements at this measurement frequency. At the same time, the metering frequency can be configured, but increasing the metering frequency will affect the battery life and shorten the service life of the meter. |
4：Does the desiccant need to be changed regularly? |
No need. After calculation, we equipped with desiccant metering, can ensure the product life cycle (16 years) moisture absorption effect. |
5：What is the storage density of the data? |
Data can be frozen by minute, hour, day, and month. |
6：Is internal metering data affected after a water meter failure? |
The "triple backup" data storage component is used to store data in three locations: chip (on-chip FRAM), off-chip EEPROM, and off-chip NFC EEPROM to ensure data storage security. If the ultrasonic water meter fails, such as power failure, crash, etc., the data can be read by mobile phone APP or NFC maintenance tool. |
