Product Introduction
The HD-DPS420 series drainage network flow monitoring station integrates Doppler flow meters, telemetry terminals, solar energy, and poles, with a high-performance low-power microcontroller as the core. It has multiple sensor interfaces and multi-channel reporting functions, and is an intelligent telemetry digital sensor that integrates data acquisition, storage, communication, and remote management functions.
This product adopts high-performance industrial grade 32-bit communication processors and industrial grade wireless modules, with an embedded real-time operating system as the software support platform. It regularly collects flow rate, water level, and transmits information to the platform, which can meet the needs of various industry applications.
Ultrasonic Doppler flow meter is a water level, velocity, and flow monitoring instrument used in rivers, open channels, and pipelines. It adopts ultrasonic detection technology, which has high measurement accuracy, high stability, little influence from environmental factors, no rotating parts, low maintenance frequency, and high work reliability. It is the preferred product for online and portable measurement.
The HD-DPS420 series drainage network flow monitoring station can communicate through GPRS/4G and other methods, and is particularly suitable for monitoring sites without mains power supply conditions and high waterproof requirements. It is mainly used for monitoring water levels in agricultural irrigation areas, drainage network water levels, reservoir and surface runoff water levels, tank liquid levels, and other monitoring scenarios.
