Product Introduction

HD-DLW120 series drainage network level meter, is the sensor, RTU, communication, power supply system, etc. integrated together, with high-performance low-power micro-controller as the core, with multiple sensor interfaces and multi-channel reporting function, is the collection of data acquisition, storage, communication and remote management and other functions in one of the intelligent telemetry digital sensors. The product adopts high-performance industrial-grade 32-bit communication processor and industrial-grade wireless module, with embedded real-time operating system as the software support platform, regularly collects the water level and transmits the information to the platform, which can meet the needs of a variety of different industry applications.
Drainage pipe network level meter, internal integration of dual redundant sensors: radar water level meter and pressure type water level meter. It can be used for network communication through 4G/GPRS, etc. It is especially suitable for monitoring sites without utility power supply conditions and with high waterproof/dustproof requirements, and is mainly used in monitoring scenarios such as water level monitoring of deep underground wells, water level monitoring of rainwater pipeline networks, and water level monitoring of drainage pipeline networks.
Functional features
※ Integration of water level sensor, RTU, housing and battery to realize water level measurement, data storage and transmission.
※ Redundant design of two water level sensors, compatible with a variety of complex manhole conditions, to ensure the normal operation of the equipment.
※ 4G (full network) remote communication, downward compatible with 3G/2G.
※ Abnormal automatic warning, timely detection of potential accidents.
※ The working mode supports two modes: timed wake-up and real-time online.
