Install WP-L80 flow totalizer (DTU)
The NB-IoT Internet of Things signal collector is integrated with the sending circuit to form a small dedicated NB-IoT Internet of Things signal collector. Its appearance is small and exquisite. It uses RS485 port to communicate with the flow totalizer, which has high measurement accuracy and good reliability. Features such as integrated circuit. It can work as long as it is connected to the communication line and power supply, avoiding unnecessary wiring and tedious installation and debugging work. The built-in circuit can communicate and store data to the flow totalizer, and send the stored data to the platform regularly. The whole machine is powered by battery or city power, the circuit is designed with low power consumption, the structure is compact, and it is easy to install. It only needs to be connected to the communication line to work. This collector is installed in the box of the flow totalizer, or installed separately in the aluminum alloy shell, and is integrated or separated with the flow totalizer, and generally does not require maintenance.
Performance indicators Flow totalizer NB data collector consists of flow totalizer and NB data collector. The flow totalizer is responsible for flow signal acquisition, calculation, display and storage. At the same time, the flow data can be output through the RS485 port. The NB data collector collects the internal data of the flow totalizer flowmeter through the RS485 port, and the data is transmitted wirelessly through the NB communication module. To the cloud platform, upload data can be accepted through the customer's application platform to achieve the purpose of remote data transmission and remote monitoring.
Flow detection, pressure detection (optional), temperature detection (optional), data passes through the NB-IoT Internet of Things wireless remote cloud server, and the user directly reads the meter data through the network computer or mobile phone using software.
