BJJL-2171 system includes: stainless steel water distribution system, tipping bucket rain gauge, electromagnetic flowmeter, turbidity meter, CR300 data collection, solar battery 
Principle: It is mainly used in the case of natural rainfall or artificial simulated rainfall, real-time online observation of small runoff residential soil and water conservation monitoring data. In the case of natural or artificial rainfall, the rain gauge starts to record the amount of rainfall and sends a signal to the CR300. The electromagnetic relay switch is then activated to supply power to the turbidity meter and the electromagnetic flowmeter. The system began to record runoff and sediment turbidity, real-time discharge and runoff accumulation. If there is no rain within 1h, the system will stop supplying power to the electromagnetic flowmeter and turbidity meter in order to save power.
Features:
Unattended 24/7
Simple operation
Save power through rain control circuit
Freely set sampling frequency and adjust clock data

Location: Zhongzhuang Ecological Observation Field, Pengyang County, Ningxia
Pengyang County is located in the hilly and gully region in the middle of the Loess Plateau and has a typical continental monsoon climate. Winter cold long, summer hot short, the daily temperature difference is large, sufficient light. Drought and little rain, but in summer, the sudden rainstorm is more frequent, fierce and concentrated. The study of runoff is of great significance to vegetation restoration and soil and water conservation in this area. In the traditional research, it is mainly carried out by placing buckets in the runoff test area to collect the runoff on the slope, which can not realize the real-time monitoring of runoff. On this basis, the runoff and sediment system developed by our company can realize real-time monitoring of rainfall, runoff turbidity, instantaneous discharge and cumulative discharge, save a lot of manpower and material resources, and also provide more detailed data for runoff research, and provide data support for ecological restoration and improvement in Pengyang area.
